### Release Notes
|
||||
|
||||
- The `mysql` input plugin has been updated fix a number of type convertion
|
||||
issues. This may cause a `field type error` when inserting into InfluxDB due
|
||||
the change of types.
|
||||
|
||||
To address this we have introduced a new `metric_version` option to control
|
||||
enabling the new format. For in depth recommendations on upgrading please
|
||||
reference the [mysql plugin documentation](./plugins/inputs/mysql/README.md#metric-version).
|
||||
|
||||
It is encouraged to migrate to the new model when possible as the old version
|
||||
is deprecated and will be removed in a future version.
|
||||
- The `mysql` input plugin has been updated to convert values to the
|
||||
correct data type. This may cause a `field type error` when inserting into
|
||||
InfluxDB due the change of types. It is recommended to drop the `mysql`,
|
||||
`mysql_variables`, and `mysql_innodb`:
|
||||
```
|

DROP MEASUREMENT mysql

DROP MEASUREMENT mysql_innodb

# Fibaro Input Plugin
|
||||
|
||||
The Fibaro plugin makes HTTP calls to the Fibaro controller API to gather values of hooked devices.
|
||||
Those values could be true (1) or false (0) for switches, percentage for dimmers, temperature, etc.
|
||||
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
# Read devices value(s) from a Fibaro controller
|
||||
[[inputs.fibaro]]
|
||||
## Required Fibaro controller address/hostname.
|
||||
## Note: at the time of writing this plugin, Fibaro only implemented http - no https available
|
||||
url = "http://<controller>:80"
|
||||
|
||||
## Required credentials to access the API (http://<controller/api/<component>)
|
||||
username = "<username>"
|
||||
password = "<password>"
|
||||
|
||||
## Amount of time allowed to complete the HTTP request
|
||||
# timeout = "5s"
|
||||
```
|
||||
|
||||
### Metrics:
|
||||
|
||||
- fibaro
|
||||
- tags:
|
||||
- section (section name)
|
||||
- room (room name)
|
||||
- name (device name)
|
||||
- type (device type)
|
||||
- fields:
|
||||
- value (float)
|
||||
- value2 (float, when available from device)
|
||||
|
||||
|
||||
### Example Output:

# HTTP Input Plugin
|
||||
|
||||
The HTTP input plugin collects metrics from one or more HTTP(S) endpoints. The endpoint should have metrics formatted in one of the supported [input data formats](../../../docs/DATA_FORMATS_INPUT.md). Each data format has its own unique set of configuration options which can be added to the input configuration.
|
||||
|
||||
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
# Read formatted metrics from one or more HTTP endpoints
|
||||
[[inputs.http]]
|
||||
## One or more URLs from which to read formatted metrics
|
||||
urls = [
|
||||
"http://localhost/metrics"
|
||||
]
|
||||
|
||||
## HTTP method
|
||||
# method = "GET"
|
||||
|
||||
## Optional HTTP headers
|
||||
# headers = {"X-Special-Header" = "Special-Value"}
|
||||
|
||||
## Optional HTTP Basic Auth Credentials
|
||||
# username = "username"
|
||||
# password = "pa$$word"
|
||||
|
||||
## Optional SSL Config
|
||||
# ssl_ca = "/etc/telegraf/ca.pem"
|
||||
# ssl_cert = "/etc/telegraf/cert.pem"
|
||||
# ssl_key = "/etc/telegraf/key.pem"
|
||||
## Use SSL but skip chain & host verification
|
||||
# insecure_skip_verify = false
|
||||
|
||||
## Amount of time allowed to complete the HTTP request
|
||||
# timeout = "5s"
|
||||
|
||||
## Data format to consume.
|
||||
## Each data format has its own unique set of configuration options, read
|
||||
## more about them here:

|
||||
# data_format = "influx"
|
||||
|
||||
```
|
||||
|
||||
### Metrics:
|
||||
|
||||
The metrics collected by this input plugin will depend on the configured `data_format` and the payload returned by the HTTP endpoint(s).
|
||||
|
||||
The default values below are added if the input format does not specify a value:
|
||||
|
||||
- http
|
||||
- tags:
|

- url

### Metrics:
|
||||
### Measurements & Fields:
|
||||
|
||||
- http_response
|
||||
- tags:
|
||||
- server (target URL)
|
||||
- method (request method)
|
||||
- status_code (response status code)
|
||||
- result ([see below](#result--result_code))
|
||||
- fields:
|
||||
- response_time (float, seconds)
|
||||
- http_response_code (int, response status code)
|
||||
- result_type (string, deprecated in 1.6: use `result` tag and `result_code` field)
|
||||
- result_code (int, [see below](#result--result_code))
|
||||
- http_response_code (int) #The code received
|
||||
- result_type (string) # success, timeout, response_string_mismatch, connection_failed
|
||||
|
||||
#### `result` / `result_code`
|
||||
|
||||
Upon finishing polling the target server, the plugin registers the result of the operation in the `result` tag, and adds a numeric field called `result_code` corresponding with that tag value.
|
||||
|
||||
This tag is used to expose network and plugin errors. HTTP errors are considered a successful connection.
|
||||
|
||||
|Tag value |Corresponding field value|Description|
|
||||
--------------------------|-------------------------|-----------|
|
||||
|success | 0 |The HTTP request completed, even if the HTTP code represents an error|
|
||||
|response_string_mismatch | 1 |The option `response_string_match` was used, and the body of the response didn't match the regex|
|
||||
|body_read_error | 2 |The option `response_string_match` was used, but the plugin wans't able to read the body of the response. Responses with empty bodies (like 3xx, HEAD, etc) will trigger this error|
|
||||
|connection_failed | 3 |Catch all for any network error not specifically handled by the plugin|
|
||||
|timeout | 4 |The plugin timed out while awaiting the HTTP connection to complete|
|
||||
|dns_error | 5 |There was a DNS error while attempting to connect to the host|
|
||||
### Tags:
|
||||
|
||||
- All measurements have the following tags:

- method

# Mcrouter Input Plugin
|
||||
|
||||
This plugin gathers statistics data from a Mcrouter server.
|
||||
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
# Read metrics from one or many mcrouter servers.
|
||||
[[inputs.mcrouter]]
|
||||
## An array of address to gather stats about. Specify an ip or hostname
|
||||
## with port. ie tcp://localhost:11211, tcp://10.0.0.1:11211, etc.
|
||||
servers = ["tcp://localhost:11211", "unix:///var/run/mcrouter.sock"]
|
||||
|
||||
## Timeout for metric collections from all servers. Minimum timeout is "1s".
|
||||
# timeout = "5s"

This connection uri may be different based on your environment and mongodb
|
||||
setup. If the user doesn't have the required privilege to execute serverStatus
|
||||
command the you will get this error on telegraf
|
||||
|
||||
#### Permissions:
|
||||
|
||||
If your MongoDB instance has access control enabled you will need to connect
|
||||
as a user with sufficient rights.
|
||||
|
||||
With MongoDB 3.4 and higher, the `clusterMonitor` role can be used. In
|
||||
version 3.2 you may also need these additional permissions:
|
||||
```
|
||||
> db.grantRolesToUser("user", [{role: "read", actions: "find", db: "local"}])
|
||||
```
|
||||
|
||||
If the user is missing required privileges you may see an error in the
|
||||
Telegraf logs similar to:
|
||||
```
|
||||
Error in input [mongodb]: not authorized on admin to execute command { serverStatus: 1, recordStats: 0 }

|
||||
#### Metric Version
|
||||
|
||||
When `metric_version = 2`, a variety of field type issues are corrected as well
|
||||
as naming inconsistencies. If you have existing data on the original version
|
||||
enabling this feature will cause a `field type error` when inserted into
|
||||
InfluxDB due to the change of types. For this reason, you should keep the
|
||||
`metric_version` unset until you are ready to migrate to the new format.
|
||||
|
||||
If preserving your old data is not required you may wish to drop conflicting
|
||||
measurements:
|
||||
```
|
||||
DROP SERIES from mysql
|
||||
DROP SERIES from mysql_variables
|
||||
DROP SERIES from mysql_innodb
|
||||
```
|
||||
|
||||
Otherwise, migration can be performed using the following steps:
|
||||
|
||||
1. Duplicate your `mysql` plugin configuration and add a `name_suffix` and
|
||||
`metric_version = 2`, this will result in collection using both the old and new
|
||||
style concurrently:
|
||||
```toml
|
||||
[[inputs.mysql]]
|
||||
servers = ["tcp(127.0.0.1:3306)/"]
|
||||
|
||||
[[inputs.mysql]]
|
||||
name_override = "_2"
|
||||
metric_version = 2
|
||||
|
||||
servers = ["tcp(127.0.0.1:3306)/"]
|
||||
```
|
||||
|
||||
2. Upgrade all affected Telegraf clients to version >=1.6.
|
||||
|
||||
New measurements will be created with the `name_suffix`, for example::
|
||||
- `mysql_v2`
|
||||
- `mysql_variables_v2`
|
||||
|
||||
3. Update charts, alerts, and other supporting code to the new format.
|
||||
4. You can now remove the old `mysql` plugin configuration and remove old
|
||||
measurements.
|
||||
|
||||
If you wish to remove the `name_suffix` you may use Kapacitor to copy the
|
||||
historical data to the default name. Do this only after retiring the old
|
||||
measurement name.
|
||||
|
||||
1. Use the techinique described above to write to multiple locations:
|
||||
```toml
|
||||
[[inputs.mysql]]
|
||||
servers = ["tcp(127.0.0.1:3306)/"]
|
||||
metric_version = 2
|
||||
|
||||
[[inputs.mysql]]
|
||||
name_override = "_2"
|
||||
metric_version = 2
|
||||
|
||||
servers = ["tcp(127.0.0.1:3306)/"]
|
||||
```
|
||||
2. Create a TICKScript to copy the historical data:
|
||||
```
|
||||
dbrp "telegraf"."autogen"
|
||||
|
||||
batch
|
||||
|query('''
|
||||
SELECT * FROM "telegraf"."autogen"."mysql_v2"
|
||||
''')
|
||||
.period(5m)
|
||||
.every(5m)
|
||||
|influxDBOut()
|
||||
.database('telegraf')
|
||||
.retentionPolicy('autogen')
|
||||
.measurement('mysql')
|
||||
```
|
||||
3. Define a task for your script:
|
||||
```sh
|
||||
kapacitor define copy-measurement -tick copy-measurement.task
|
||||
```
|
||||
4. Run the task over the data you would like to migrate:
|
||||
```sh
|
||||
kapacitor replay-live batch -start 2018-03-30T20:00:00Z -stop 2018-04-01T12:00:00Z -rec-time -task copy-measurement
|
||||
```
|
||||
5. Verify copied data and repeat for other measurements.
|
||||
|
||||
### Metrics:
|
||||

|
||||
* Global statuses - all numeric and boolean values of `SHOW GLOBAL STATUSES`
|
||||
* Global variables - all numeric and boolean values of `SHOW GLOBAL VARIABLES`
