## v1.0 beta 3 [2016-07-18]
### Release Notes
**Breaking Change** The SNMP plugin is being deprecated in it's current form.
There is a [new SNMP plugin](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/snmp)
which fixes many of the issues and confusions
of it's predecessor. For users wanting to continue to use the deprecated SNMP
plugin, you will need to change your config file from `[[inputs.snmp]]` to
`[[inputs.snmp_legacy]]`. The configuration of the new SNMP plugin is _not_
backwards-compatible.
- Telegraf now supports being installed as an official windows service,
which can be installed via
`> C:\Program Files\Telegraf\telegraf.exe --service install`
**Breaking Change**: Aerospike main server node measurements have been renamed
aerospike_node. Aerospike namespace measurements have been renamed to
aerospike_namespace. They will also now be tagged with the node_name

- `flush_jitter` behavior has been changed. The random jitter will now be
evaluated at every flush interval, rather than once at startup. This makes it
consistent with the behavior of `collection_jitter`.

## v1.0 beta 1 [2016-06-07]
### Release Notes
- `flush_jitter` behavior has been changed. The random jitter will now be
evaluated at every flush interval, rather than once at startup. This makes it
consistent with the behavior of `collection_jitter`.
- All AWS plugins now utilize a standard mechanism for evaluating credentials.
This allows all AWS plugins to support environment variables, shared credential
files & profiles, and role assumptions. See the specific plugin README for
details.
- The AWS CloudWatch input plugin can now declare a wildcard value for a metric
dimension. This causes the plugin to read all metrics that contain the specified
dimension key regardless of value. This is used to export collections of metrics
without having to know the dimension values ahead of time.
- The AWS CloudWatch input plugin can now be configured with the `cache_ttl`
attribute. This configures the TTL of the internal metric cache. This is useful
in conjunction with wildcard dimension values as it will control the amount of
time before a new metric is included by the plugin.

# Running Telegraf as a Windows Service
If you have tried to install Go binaries as Windows Services with the **sc.exe**
tool you may have seen that the service errors and stops running after a while.
Telegraf natively supports running as a Windows Service. Outlined below is are
the general steps to set it up.
**NSSM** (the Non-Sucking Service Manager) is a tool that helps you in a
[number of scenarios](http://nssm.cc/scenarios) including running Go binaries
that were not specifically designed to run only in Windows platforms.
1. Obtain the telegraf windows distribution
2. Create the directory `C:\Program Files\Telegraf` (if you install in a different
location simply specify the `-config` parameter with the desired location)
3. Place the telegraf.exe and the config file into `C:\Program Files\Telegraf`
4. To install the service into the Windows Service Manager, run (as an
administrator):
## NSSM Installation via Chocolatey
```
> C:\Program Files\Telegraf\telegraf.exe --service install
```
You can install [Chocolatey](https://chocolatey.org/) and [NSSM](http://nssm.cc/)
with these commands
5. Edit the configuration file to meet your needs
6. To check that it works, run:
```powershell
iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
choco install -y nssm
```
```
> C:\Program Files\Telegraf\telegraf.exe --config C:\Program Files\Telegraf\telegraf.conf --test
```
## Installing Telegraf as a Windows Service with NSSM
7. To start collecting data, run:
You can download the latest Telegraf Windows binaries (still Experimental at
the moment) from [the Telegraf Github repo](https://github.com/influxdata/telegraf).
```
> net start telegraf
```
Then you can create a C:\telegraf folder, unzip the binary there and modify the
**telegraf.conf** sample to allocate the metrics you want to send to **InfluxDB**.
## Other supported operations
Once you have NSSM installed in your system, the process is quite straightforward.
You only need to type this command in your Windows shell
Telegraf can manage its own service through the --service flag:
```powershell
nssm install Telegraf c:\telegraf\telegraf.exe -config c:\telegraf\telegraf.config
```
| Command | Effect |
|------------------------------------|-------------------------------|
| `telegraf.exe --service install` | Install telegraf as a service |
| `telegraf.exe --service uninstall` | Remove the telegraf service |
| `telegraf.exe --service start` | Start the telegraf service |
| `telegraf.exe --service stop` | Stop the telegraf service |
And now your service will be installed in Windows and you will be able to start and
stop it gracefully

# Ping input plugin
This input plugin will measures the round-trip
## Windows:
### Configration:
```
## urls to ping
urls = ["www.google.com"] # required
## number of pings to send per collection (ping -n <COUNT>)
count = 4 # required
## Ping timeout, in seconds. 0 means default timeout (ping -w <TIMEOUT>)
Timeout = 0
```
### Measurements & Fields:
- packets_transmitted ( from ping output )
- reply_received ( increasing only on valid metric from echo replay, eg. 'Destination net unreachable' reply will increment packets_received but not reply_received )
- packets_received ( from ping output )
- percent_reply_loss ( compute from packets_transmitted and reply_received )
- percent_packets_loss ( compute from packets_transmitted and packets_received )
- errors ( when host can not be found or wrong prameters is passed to application )
- response time
- average_response_ms ( compute from minimum_response_ms and maximum_response_ms )
- minimum_response_ms ( from ping output )
- maximum_response_ms ( from ping output )
### Tags:
- server
### Example Output:

# sensors Input Plugin
Collect [lm-sensors](https://en.wikipedia.org/wiki/Lm_sensors) metrics - requires the lm-sensors
package installed.
This plugin collects sensor metrics with the `sensors` executable from the lm-sensor package.
### Configuration:
```
# Monitor sensors, requires lm-sensors package
[[inputs.sensors]]
## Remove numbers from field names.
## If true, a field name like 'temp1_input' will be changed to 'temp_input'.
# remove_numbers = true
```
### Measurements & Fields:
Fields are created dynamicaly depending on the sensors. All fields are float.
### Tags:
- All measurements have the following tags:
- chip
- feature
### Example Output:
#### Default
```
$ telegraf -config telegraf.conf -input-filter sensors -test

# SNMP Input Plugin
# SNMP Plugin
The SNMP input plugin gathers metrics from SNMP agents
The SNMP input plugin gathers metrics from SNMP agents.
### Configuration:
## Configuration:
### Example:
#### Very simple example
In this example, the plugin will gather value of OIDS:
- `.1.3.6.1.2.1.2.2.1.4.1`
```toml
# Very Simple Example
[[inputs.snmp]]
[[inputs.snmp.host]]
address = "127.0.0.1:161"
# SNMP community
community = "public" # default public
# SNMP version (1, 2 or 3)
# Version 3 not supported yet
version = 2 # default 2
# Simple list of OIDs to get, in addition to "collect"
get_oids = [".1.3.6.1.2.1.2.2.1.4.1"]
SNMP data:
```
.1.0.0.0.1.1.0 octet_str "foo"
.1.0.0.0.1.1.1 octet_str "bar"
.1.0.0.0.1.102 octet_str "bad"
.1.0.0.0.1.2.0 integer 1
.1.0.0.0.1.2.1 integer 2
.1.0.0.0.1.3.0 octet_str "0.123"
.1.0.0.0.1.3.1 octet_str "0.456"
.1.0.0.0.1.3.2 octet_str "9.999"
.1.0.0.1.1 octet_str "baz"
.1.0.0.1.2 uinteger 54321
.1.0.0.1.3 uinteger 234
```
#### Simple example
In this example, Telegraf gathers value of OIDS:
- named **ifnumber**
- named **interface_speed**
With **inputs.snmp.get** section the plugin gets the oid number:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed*
As you can see *ifSpeed* is not a valid OID. In order to get
the valid OID, the plugin uses `snmptranslate_file` to match the OID:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed* => `.1.3.6.1.2.1.2.2.1.5`
Also as the plugin will append `instance` to the corresponding OID:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed* => `.1.3.6.1.2.1.2.2.1.5.1`
In this example, the plugin will gather value of OIDS:
- `.1.3.6.1.2.1.2.1.0`
- `.1.3.6.1.2.1.2.2.1.5.1`
Telegraf config:

#### Simple bulk example
In this example, Telegraf gathers value of OIDS:
- named **ifnumber**
- named **interface_speed**
- named **if_out_octets**
With **inputs.snmp.get** section the plugin gets oid number:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed*
With **inputs.snmp.bulk** section the plugin gets the oid number:
- **if_out_octets** => *ifOutOctets*
As you can see *ifSpeed* and *ifOutOctets* are not a valid OID.
In order to get the valid OID, the plugin uses `snmptranslate_file`
to match the OID:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed* => `.1.3.6.1.2.1.2.2.1.5`
- **if_out_octets** => *ifOutOctets* => `.1.3.6.1.2.1.2.2.1.16`
Also, the plugin will append `instance` to the corresponding OID:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed* => `.1.3.6.1.2.1.2.2.1.5.1`
And **if_out_octets** is a bulk request, the plugin will gathers all
OIDS in the table.
- `.1.3.6.1.2.1.2.2.1.16.1`
- `.1.3.6.1.2.1.2.2.1.16.2`
- `.1.3.6.1.2.1.2.2.1.16.3`
- `.1.3.6.1.2.1.2.2.1.16.4`
- `.1.3.6.1.2.1.2.2.1.16.5`
- `...`
In this example, the plugin will gather value of OIDS:
- `.1.3.6.1.2.1.2.1.0`
- `.1.3.6.1.2.1.2.2.1.5.1`
- `.1.3.6.1.2.1.2.2.1.16.1`
- `.1.3.6.1.2.1.2.2.1.16.2`
- `.1.3.6.1.2.1.2.2.1.16.3`
- `.1.3.6.1.2.1.2.2.1.16.4`
- `.1.3.6.1.2.1.2.2.1.16.5`

#### Table example
In this example, we remove collect attribute to the host section,
but you can still use it in combination of the following part.
Note: This example is like a bulk request a but using an
other configuration
Telegraf gathers value of OIDS of the table:
- named **iftable1**
With **inputs.snmp.table** section the plugin gets oid number:
- **iftable1** => `.1.3.6.1.2.1.31.1.1.1`
Also **iftable1** is a table, the plugin will gathers all
OIDS in the table and in the subtables
- `.1.3.6.1.2.1.31.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.2`

#### Table with subtable example
In this example, we remove collect attribute to the host section,
but you can still use it in combination of the following part.
Note: This example is like a bulk request a but using an
other configuration
Telegraf gathers value of OIDS of the table:
- named **iftable2**
With **inputs.snmp.table** section *AND* **sub_tables** attribute,
the plugin will get OIDS from subtables:
- **iftable2** => `.1.3.6.1.2.1.2.2.1.13`
Also **iftable2** is a table, the plugin will gathers all
OIDS in subtables:
- `.1.3.6.1.2.1.2.2.1.13.1`
- `.1.3.6.1.2.1.2.2.1.13.2`
- `.1.3.6.1.2.1.2.2.1.13.3`
- `.1.3.6.1.2.1.2.2.1.13.4`
- `.1.3.6.1.2.1.2.2.1.13....`
#### Configuration via MIB:
This example uses the SNMP data above, but is configured via the MIB.
The example MIB file can be found in the `testdata` directory. See the [MIB lookups](#mib-lookups) section for more information.
Telegraf config:
```toml

oid = "TEST::testTable"
inherit_tags = "hostname"
```
#### Table with mapping example
In this example, we remove collect attribute to the host section,
but you can still use it in combination of the following part.
Telegraf gathers value of OIDS of the table:
- named **iftable3**
With **inputs.snmp.table** section the plugin gets oid number:
- **iftable3** => `.1.3.6.1.2.1.31.1.1.1`
Also **iftable2** is a table, the plugin will gathers all
OIDS in the table and in the subtables
- `.1.3.6.1.2.1.31.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.2`
- `.1.3.6.1.2.1.31.1.1.1.1.3`
- `.1.3.6.1.2.1.31.1.1.1.1.4`
- `.1.3.6.1.2.1.31.1.1.1.1....`
- `.1.3.6.1.2.1.31.1.1.1.2`
- `.1.3.6.1.2.1.31.1.1.1.2....`
- `.1.3.6.1.2.1.31.1.1.1.3`

- `.1.3.6.1.2.1.31.1.1.1.5`
- `.1.3.6.1.2.1.31.1.1.1.5....`
- `.1.3.6.1.2.1.31.1.1.1.6....`
- `...`
But the **include_instances** attribute will filter which OIDS
will be gathered; As you see, there is an other attribute, `mapping_table`.
`include_instances` and `mapping_table` permit to build a hash table
to filter only OIDS you want.
Let's say, we have the following data on SNMP server:
- OID: `.1.3.6.1.2.1.31.1.1.1.1.1` has as value: `enp5s0`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.2` has as value: `enp5s1`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.3` has as value: `enp5s2`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.4` has as value: `eth0`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.5` has as value: `eth1`
The plugin will build the following hash table:
| instance name | instance id |
|---------------|-------------|
| `enp5s0` | `1` |
| `enp5s1` | `2` |
| `enp5s2` | `3` |
| `eth0` | `4` |
| `eth1` | `5` |
With the **include_instances** attribute, the plugin will gather
the following OIDS:
- `.1.3.6.1.2.1.31.1.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.5`
- `.1.3.6.1.2.1.31.1.1.1.2.1`
- `.1.3.6.1.2.1.31.1.1.1.2.5`
- `.1.3.6.1.2.1.31.1.1.1.3.1`
- `.1.3.6.1.2.1.31.1.1.1.3.5`
- `.1.3.6.1.2.1.31.1.1.1.4.1`

- `.1.3.6.1.2.1.31.1.1.1.6.1`
- `.1.3.6.1.2.1.31.1.1.1.6.5`

### Config parameters
#### Table with both mapping and subtable example
* `agents`: Default: `[]`
List of SNMP agents to connect to in the form of `IP[:PORT]`. If `:PORT` is unspecified, it defaults to `161`.
In this example, we remove collect attribute to the host section,
but you can still use it in combination of the following part.
* `version`: Default: `2`
SNMP protocol version to use.
Telegraf gathers value of OIDS of the table:
* `community`: Default: `"public"`
SNMP community to use.
- named **iftable4**
* `max_repetitions`: Default: `50`
Maximum number of iterations for repeating variables.
With **inputs.snmp.table** section *AND* **sub_tables** attribute,
the plugin will get OIDS from subtables:

Security name for authenticated SNMPv3 requests.
- **iftable4** => `.1.3.6.1.2.1.31.1.1.1`
* `auth_protocol`: Values: `"MD5"`,`"SHA"`,`""`. Default: `""`

Security level used for SNMPv3 messages.
But the **include_instances** attribute will filter which OIDS
will be gathered; As you see, there is an other attribute, `mapping_table`.
`include_instances` and `mapping_table` permit to build a hash table
to filter only OIDS you want.
Let's say, we have the following data on SNMP server:
- OID: `.1.3.6.1.2.1.31.1.1.1.1.1` has as value: `enp5s0`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.2` has as value: `enp5s1`

- OID: `.1.3.6.1.2.1.31.1.1.1.1.4` has as value: `eth0`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.5` has as value: `eth1`
* `context_name`:
Context name used for SNMPv3 requests.
The plugin will build the following hash table:
* `priv_protocol`: Values: `"DES"`,`"AES"`,`""`. Default: `""`
Privacy protocol used for encrypted SNMPv3 messages.
| instance name | instance id |
|---------------|-------------|
| `enp5s0` | `1` |
| `enp5s1` | `2` |
| `enp5s2` | `3` |
| `eth0` | `4` |
| `eth1` | `5` |
With the **include_instances** attribute, the plugin will gather
the following OIDS:
- `.1.3.6.1.2.1.31.1.1.1.6.1`
- `.1.3.6.1.2.1.31.1.1.1.6.5`
- `.1.3.6.1.2.1.31.1.1.1.10.1`
- `.1.3.6.1.2.1.31.1.1.1.10.5`
Note: the plugin will add instance name as tag *instance*
* `priv_password`:
Privacy password used for encrypted SNMPv3 messages.
* `name`:
Output measurement name.

# Which table do you want to collect
[[inputs.snmp.host.table]]
name = "iftable4"
include_instances = ["enp5s0", "eth1"]
#### Field parameters:
* `oid`:
OID to get. May be a numeric or textual OID.
# table with both mapping and subtables
[[inputs.snmp.table]]
name = "iftable4"
# if empty get all instances
mapping_table = ".1.3.6.1.2.1.31.1.1.1.1"

# sub_tables could be not "real subtables"
sub_tables=[".1.3.6.1.2.1.2.2.1.13", "bytes_recv", "bytes_send"]
# note
# oid attribute is useless
* `name`:
Output field/tag name.
If not specified, it defaults to the value of `oid`. If `oid` is numeric, an attempt to translate the numeric OID into a texual OID will be made.
# SNMP SUBTABLES
[[inputs.snmp.subtable]]
name = "bytes_recv"
oid = ".1.3.6.1.2.1.31.1.1.1.6"
unit = "octets"
* `is_tag`:
Output this field as a tag.
[[inputs.snmp.subtable]]
name = "bytes_send"
oid = ".1.3.6.1.2.1.31.1.1.1.10"
unit = "octets"
```
* `conversion`: Values: `"float(X)"`,`"float"`,`"int"`,`""`. Default: `""`
Converts the value according to the given specification.
#### Configuration notes
- `float(X)`: Converts the input value into a float and divides by the Xth power of 10. Efficively just moves the decimal left X places. For example a value of `123` with `float(2)` will result in `1.23`.
- `float`: Converts the value into a float with no adjustment. Same as `float(0)`.
- `int`: Convertes the value into an integer.
- In **inputs.snmp.table** section, the `oid` attribute is useless if
the `sub_tables` attributes is defined
#### Table parameters:
* `oid`:
Automatically populates the table's fields using data from the MIB.
- In **inputs.snmp.subtable** section, you can put a name from `snmptranslate_file`
as `oid` attribute instead of a valid OID
* `name`:
Output measurement name.
If not specified, it defaults to the value of `oid`. If `oid` is numeric, an attempt to translate the numeric OID into a texual OID will be made.
### Measurements & Fields:
* `inherit_tags`:
Which tags to inherit from the top-level config and to use in the output of this table's measurement.
With the last example (Table with both mapping and subtable example):
### MIB lookups
If the plugin is configured such that it needs to perform lookups from the MIB, it will use the net-snmp utilities `snmptranslate` and `snmptable`.
- ifHCOutOctets
- ifHCOutOctets
- ifInDiscards
- ifInDiscards
- ifHCInOctets
- ifHCInOctets

When performing the lookups, the plugin will load all available MIBs. If your MIB files are in a custom path, you may add the path using the `MIBDIRS` environment variable. See [`man 1 snmpcmd`](http://net-snmp.sourceforge.net/docs/man/snmpcmd.html#lbAK) for more information on the variable.

# SNMP Input Plugin
The SNMP input plugin gathers metrics from SNMP agents
### Configuration:
#### Very simple example
In this example, the plugin will gather value of OIDS:
- `.1.3.6.1.2.1.2.2.1.4.1`
```toml
# Very Simple Example
[[inputs.snmp]]
[[inputs.snmp.host]]
address = "127.0.0.1:161"
# SNMP community
community = "public" # default public
# SNMP version (1, 2 or 3)
# Version 3 not supported yet
version = 2 # default 2
# Simple list of OIDs to get, in addition to "collect"
get_oids = [".1.3.6.1.2.1.2.2.1.4.1"]
```
#### Simple example
In this example, Telegraf gathers value of OIDS:
- named **ifnumber**
- named **interface_speed**
With **inputs.snmp.get** section the plugin gets the oid number:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed*
As you can see *ifSpeed* is not a valid OID. In order to get
the valid OID, the plugin uses `snmptranslate_file` to match the OID:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed* => `.1.3.6.1.2.1.2.2.1.5`
Also as the plugin will append `instance` to the corresponding OID:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed* => `.1.3.6.1.2.1.2.2.1.5.1`
In this example, the plugin will gather value of OIDS:
- `.1.3.6.1.2.1.2.1.0`
- `.1.3.6.1.2.1.2.2.1.5.1`
```toml
# Simple example
[[inputs.snmp]]
## Use 'oids.txt' file to translate oids to names
## To generate 'oids.txt' you need to run:
## snmptranslate -m all -Tz -On | sed -e 's/"//g' > /tmp/oids.txt
## Or if you have an other MIB folder with custom MIBs
## snmptranslate -M /mycustommibfolder -Tz -On -m all | sed -e 's/"//g' > oids.txt
snmptranslate_file = "/tmp/oids.txt"
[[inputs.snmp.host]]
address = "127.0.0.1:161"
# SNMP community
community = "public" # default public
# SNMP version (1, 2 or 3)
# Version 3 not supported yet
version = 2 # default 2
# Which get/bulk do you want to collect for this host
collect = ["ifnumber", "interface_speed"]
[[inputs.snmp.get]]
name = "ifnumber"
oid = ".1.3.6.1.2.1.2.1.0"
[[inputs.snmp.get]]
name = "interface_speed"
oid = "ifSpeed"
instance = "1"
```
#### Simple bulk example
In this example, Telegraf gathers value of OIDS:
- named **ifnumber**
- named **interface_speed**
- named **if_out_octets**
With **inputs.snmp.get** section the plugin gets oid number:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed*
With **inputs.snmp.bulk** section the plugin gets the oid number:
- **if_out_octets** => *ifOutOctets*
As you can see *ifSpeed* and *ifOutOctets* are not a valid OID.
In order to get the valid OID, the plugin uses `snmptranslate_file`
to match the OID:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed* => `.1.3.6.1.2.1.2.2.1.5`
- **if_out_octets** => *ifOutOctets* => `.1.3.6.1.2.1.2.2.1.16`
Also, the plugin will append `instance` to the corresponding OID:
- **ifnumber** => `.1.3.6.1.2.1.2.1.0`
- **interface_speed** => *ifSpeed* => `.1.3.6.1.2.1.2.2.1.5.1`
And **if_out_octets** is a bulk request, the plugin will gathers all
OIDS in the table.
- `.1.3.6.1.2.1.2.2.1.16.1`
- `.1.3.6.1.2.1.2.2.1.16.2`
- `.1.3.6.1.2.1.2.2.1.16.3`
- `.1.3.6.1.2.1.2.2.1.16.4`
- `.1.3.6.1.2.1.2.2.1.16.5`
- `...`
In this example, the plugin will gather value of OIDS:
- `.1.3.6.1.2.1.2.1.0`
- `.1.3.6.1.2.1.2.2.1.5.1`
- `.1.3.6.1.2.1.2.2.1.16.1`
- `.1.3.6.1.2.1.2.2.1.16.2`
- `.1.3.6.1.2.1.2.2.1.16.3`
- `.1.3.6.1.2.1.2.2.1.16.4`
- `.1.3.6.1.2.1.2.2.1.16.5`
- `...`
```toml
# Simple bulk example
[[inputs.snmp]]
## Use 'oids.txt' file to translate oids to names
## To generate 'oids.txt' you need to run:
## snmptranslate -m all -Tz -On | sed -e 's/"//g' > /tmp/oids.txt
## Or if you have an other MIB folder with custom MIBs
## snmptranslate -M /mycustommibfolder -Tz -On -m all | sed -e 's/"//g' > oids.txt
snmptranslate_file = "/tmp/oids.txt"
[[inputs.snmp.host]]
address = "127.0.0.1:161"
# SNMP community
community = "public" # default public
# SNMP version (1, 2 or 3)
# Version 3 not supported yet
version = 2 # default 2
# Which get/bulk do you want to collect for this host
collect = ["interface_speed", "if_number", "if_out_octets"]
[[inputs.snmp.get]]
name = "interface_speed"
oid = "ifSpeed"
instance = "1"
[[inputs.snmp.get]]
name = "if_number"
oid = "ifNumber"
[[inputs.snmp.bulk]]
name = "if_out_octets"
oid = "ifOutOctets"
```
#### Table example
In this example, we remove collect attribute to the host section,
but you can still use it in combination of the following part.
Note: This example is like a bulk request a but using an
other configuration
Telegraf gathers value of OIDS of the table:
- named **iftable1**
With **inputs.snmp.table** section the plugin gets oid number:
- **iftable1** => `.1.3.6.1.2.1.31.1.1.1`
Also **iftable1** is a table, the plugin will gathers all
OIDS in the table and in the subtables
- `.1.3.6.1.2.1.31.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.2`
- `.1.3.6.1.2.1.31.1.1.1.1.3`
- `.1.3.6.1.2.1.31.1.1.1.1.4`
- `.1.3.6.1.2.1.31.1.1.1.1....`
- `.1.3.6.1.2.1.31.1.1.1.2`
- `.1.3.6.1.2.1.31.1.1.1.2....`

# table without mapping neither subtables
# This is like bulk request
[[inputs.snmp.table]]
name = "iftable1"
oid = ".1.3.6.1.2.1.31.1.1.1"
```
#### Table with subtable example
In this example, we remove collect attribute to the host section,
but you can still use it in combination of the following part.
Note: This example is like a bulk request a but using an
other configuration
Telegraf gathers value of OIDS of the table:
- named **iftable2**
With **inputs.snmp.table** section *AND* **sub_tables** attribute,
the plugin will get OIDS from subtables:
- **iftable2** => `.1.3.6.1.2.1.2.2.1.13`
Also **iftable2** is a table, the plugin will gathers all
OIDS in subtables:
- `.1.3.6.1.2.1.2.2.1.13.1`
- `.1.3.6.1.2.1.2.2.1.13.2`
- `.1.3.6.1.2.1.2.2.1.13.3`
- `.1.3.6.1.2.1.2.2.1.13.4`
- `.1.3.6.1.2.1.2.2.1.13....`
```toml

name = "iftable2"
sub_tables = [".1.3.6.1.2.1.2.2.1.13"]
# note
# oid attribute is useless
```
#### Table with mapping example
In this example, we remove collect attribute to the host section,
but you can still use it in combination of the following part.
Telegraf gathers value of OIDS of the table:
- named **iftable3**
With **inputs.snmp.table** section the plugin gets oid number:
- **iftable3** => `.1.3.6.1.2.1.31.1.1.1`
Also **iftable2** is a table, the plugin will gathers all
OIDS in the table and in the subtables
- `.1.3.6.1.2.1.31.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.2`
- `.1.3.6.1.2.1.31.1.1.1.1.3`
- `.1.3.6.1.2.1.31.1.1.1.1.4`
- `.1.3.6.1.2.1.31.1.1.1.1....`
- `.1.3.6.1.2.1.31.1.1.1.2`
- `.1.3.6.1.2.1.31.1.1.1.2....`
- `.1.3.6.1.2.1.31.1.1.1.3`
- `.1.3.6.1.2.1.31.1.1.1.3....`
- `.1.3.6.1.2.1.31.1.1.1.4`
- `.1.3.6.1.2.1.31.1.1.1.4....`
- `.1.3.6.1.2.1.31.1.1.1.5`
- `.1.3.6.1.2.1.31.1.1.1.5....`
- `.1.3.6.1.2.1.31.1.1.1.6....`
- `...`
But the **include_instances** attribute will filter which OIDS
will be gathered; As you see, there is an other attribute, `mapping_table`.
`include_instances` and `mapping_table` permit to build a hash table
to filter only OIDS you want.
Let's say, we have the following data on SNMP server:
- OID: `.1.3.6.1.2.1.31.1.1.1.1.1` has as value: `enp5s0`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.2` has as value: `enp5s1`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.3` has as value: `enp5s2`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.4` has as value: `eth0`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.5` has as value: `eth1`
The plugin will build the following hash table:
| instance name | instance id |
|---------------|-------------|
| `enp5s0` | `1` |
| `enp5s1` | `2` |
| `enp5s2` | `3` |
| `eth0` | `4` |
| `eth1` | `5` |
With the **include_instances** attribute, the plugin will gather
the following OIDS:
- `.1.3.6.1.2.1.31.1.1.1.1.1`
- `.1.3.6.1.2.1.31.1.1.1.1.5`
- `.1.3.6.1.2.1.31.1.1.1.2.1`
- `.1.3.6.1.2.1.31.1.1.1.2.5`
- `.1.3.6.1.2.1.31.1.1.1.3.1`
- `.1.3.6.1.2.1.31.1.1.1.3.5`
- `.1.3.6.1.2.1.31.1.1.1.4.1`
- `.1.3.6.1.2.1.31.1.1.1.4.5`
- `.1.3.6.1.2.1.31.1.1.1.5.1`
- `.1.3.6.1.2.1.31.1.1.1.5.5`
- `.1.3.6.1.2.1.31.1.1.1.6.1`
- `.1.3.6.1.2.1.31.1.1.1.6.5`
- `...`
Note: the plugin will add instance name as tag *instance*
```toml
# Simple table with mapping example
[[inputs.snmp]]
## Use 'oids.txt' file to translate oids to names
## To generate 'oids.txt' you need to run:
## snmptranslate -m all -Tz -On | sed -e 's/"//g' > /tmp/oids.txt
## Or if you have an other MIB folder with custom MIBs
## snmptranslate -M /mycustommibfolder -Tz -On -m all | sed -e 's/"//g' > oids.txt
snmptranslate_file = "/tmp/oids.txt"
[[inputs.snmp.host]]
address = "127.0.0.1:161"
# SNMP community
community = "public" # default public
# SNMP version (1, 2 or 3)
# Version 3 not supported yet
version = 2 # default 2
# Which table do you want to collect
[[inputs.snmp.host.table]]
name = "iftable3"
include_instances = ["enp5s0", "eth1"]
# table with mapping but without subtables
[[inputs.snmp.table]]
name = "iftable3"
oid = ".1.3.6.1.2.1.31.1.1.1"
# if empty. get all instances
mapping_table = ".1.3.6.1.2.1.31.1.1.1.1"
# if empty, get all subtables
```
#### Table with both mapping and subtable example
In this example, we remove collect attribute to the host section,
but you can still use it in combination of the following part.
Telegraf gathers value of OIDS of the table:
- named **iftable4**
With **inputs.snmp.table** section *AND* **sub_tables** attribute,
the plugin will get OIDS from subtables:
- **iftable4** => `.1.3.6.1.2.1.31.1.1.1`
Also **iftable2** is a table, the plugin will gathers all
OIDS in the table and in the subtables
- `.1.3.6.1.2.1.31.1.1.1.6.1
- `.1.3.6.1.2.1.31.1.1.1.6.2`
- `.1.3.6.1.2.1.31.1.1.1.6.3`
- `.1.3.6.1.2.1.31.1.1.1.6.4`
- `.1.3.6.1.2.1.31.1.1.1.6....`
- `.1.3.6.1.2.1.31.1.1.1.10.1`
- `.1.3.6.1.2.1.31.1.1.1.10.2`
- `.1.3.6.1.2.1.31.1.1.1.10.3`
- `.1.3.6.1.2.1.31.1.1.1.10.4`
- `.1.3.6.1.2.1.31.1.1.1.10....`
But the **include_instances** attribute will filter which OIDS
will be gathered; As you see, there is an other attribute, `mapping_table`.
`include_instances` and `mapping_table` permit to build a hash table
to filter only OIDS you want.
Let's say, we have the following data on SNMP server:
- OID: `.1.3.6.1.2.1.31.1.1.1.1.1` has as value: `enp5s0`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.2` has as value: `enp5s1`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.3` has as value: `enp5s2`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.4` has as value: `eth0`
- OID: `.1.3.6.1.2.1.31.1.1.1.1.5` has as value: `eth1`
The plugin will build the following hash table:
| instance name | instance id |
|---------------|-------------|
| `enp5s0` | `1` |
| `enp5s1` | `2` |
| `enp5s2` | `3` |
| `eth0` | `4` |
| `eth1` | `5` |
With the **include_instances** attribute, the plugin will gather
the following OIDS:
- `.1.3.6.1.2.1.31.1.1.1.6.1`
- `.1.3.6.1.2.1.31.1.1.1.6.5`
- `.1.3.6.1.2.1.31.1.1.1.10.1`
- `.1.3.6.1.2.1.31.1.1.1.10.5`
Note: the plugin will add instance name as tag *instance*

# if empty get all subtables
# sub_tables could be not "real subtables"
sub_tables=[".1.3.6.1.2.1.2.2.1.13", "bytes_recv", "bytes_send"]
# note
# oid attribute is useless
# SNMP SUBTABLES
[[inputs.snmp.subtable]]
name = "bytes_recv"
oid = ".1.3.6.1.2.1.31.1.1.1.6"
unit = "octets"
[[inputs.snmp.subtable]]
name = "bytes_send"
oid = ".1.3.6.1.2.1.31.1.1.1.10"
unit = "octets"
```
#### Configuration notes
- In **inputs.snmp.table** section, the `oid` attribute is useless if
the `sub_tables` attributes is defined
- In **inputs.snmp.subtable** section, you can put a name from `snmptranslate_file`
as `oid` attribute instead of a valid OID

# Kafka Producer Output Plugin
This plugin writes to a [Kafka Broker](http://kafka.apache.org/07/quickstart.html) acting a Kafka Producer.
```
[[outputs.kafka]]
## URLs of kafka brokers
brokers = ["localhost:9092"]
## Kafka topic for producer messages
topic = "telegraf"
## Telegraf tag to use as a routing key
## ie, if this tag exists, it's value will be used as the routing key
routing_tag = "host"
## CompressionCodec represents the various compression codecs recognized by
## Kafka in messages.
## 0 : No compression
## 1 : Gzip compression
## 2 : Snappy compression
compression_codec = 0
## RequiredAcks is used in Produce Requests to tell the broker how many
## replica acknowledgements it must see before responding
## 0 : the producer never waits for an acknowledgement from the broker.
## This option provides the lowest latency but the weakest durability
## guarantees (some data will be lost when a server fails).
## 1 : the producer gets an acknowledgement after the leader replica has
## received the data. This option provides better durability as the
## client waits until the server acknowledges the request as successful
## (only messages that were written to the now-dead leader but not yet
## replicated will be lost).
## -1: the producer gets an acknowledgement after all in-sync replicas have
## received the data. This option provides the best durability, we
## guarantee that no messages will be lost as long as at least one in
## sync replica remains.
required_acks = -1
## The total number of times to retry sending a message
max_retry = 3
## Optional SSL Config

```
### Required parameters:
* `brokers`: List of strings, this is for speaking to a cluster of `kafka` brokers. On each flush interval, Telegraf will randomly choose one of the urls to write to. Each URL should just include host and port e.g. -> `["{host}:{port}","{host2}:{port2}"]`
* `topic`: The `kafka` topic to publish to.
### Optional parameters:
* `routing_tag`: if this tag exists, it's value will be used as the routing key
* `compression_codec`: What level of compression to use: `0` -> no compression, `1` -> gzip compression, `2` -> snappy compression
* `required_acks`: a setting for how may `acks` required from the `kafka` broker cluster.
* `max_retry`: Max number of times to retry failed write
* `ssl_ca`: SSL CA
* `ssl_cert`: SSL CERT
* `ssl_key`: SSL key
* `insecure_skip_verify`: Use SSL but skip chain & host verification (default: false)
* `data_format`: [About Telegraf data formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md)
