# Telegraf Configuration
## Plugin Configuration
There are some configuration options that are configurable per plugin:
* **name_override**: Override the base name of the measurement.
(Default is the name of the plugin).
* **name_prefix**: Specifies a prefix to attach to the measurement name.
* **name_suffix**: Specifies a suffix to attach to the measurement name.
* **tags**: A map of tags to apply to a specific plugin's measurements.
### Plugin Filters
There are also filters that can be configured per plugin:
* **pass**: An array of strings that is used to filter metrics generated by the
current plugin. Each string in the array is tested as a glob match against field names
and if it matches, the field is emitted.
* **drop**: The inverse of pass, if a field name matches, it is not emitted.
* **tagpass**: tag names and arrays of strings that are used to filter
measurements by the current plugin. Each string in the array is tested as a glob
match against the tag name, and if it matches the measurement is emitted.
* **tagdrop**: The inverse of tagpass. If a tag matches, the measurement is not emitted.
This is tested on measurements that have passed the tagpass test.
* **interval**: How often to gather this metric. Normal plugins use a single
global interval, but if one particular plugin should be run less or more often,
you can configure that here.
### Plugin Configuration Examples
This is a full working config that will output CPU data to an InfluxDB instance
at 192.168.59.103:8086, tagging measurements with dc="denver-1". It will output
measurements at a 10s interval and will collect per-cpu data, dropping any
fields which begin with `time_`.
```toml
[tags]
dc = "denver-1"
[agent]
interval = "10s"
# OUTPUTS
[outputs]
[[outputs.influxdb]]
url = "http://192.168.59.103:8086" # required.
database = "telegraf" # required.
precision = "s"
# PLUGINS
[plugins]
[[plugins.cpu]]
percpu = true
totalcpu = false
# filter all fields beginning with 'time_'
drop = ["time_*"]
```
### Plugin Config: tagpass and tagdrop
```toml
[plugins]
[[plugins.cpu]]
percpu = true
totalcpu = false
drop = ["cpu_time"]
# Don't collect CPU data for cpu6 & cpu7
[plugins.cpu.tagdrop]
cpu = [ "cpu6", "cpu7" ]
[[plugins.disk]]
[plugins.disk.tagpass]
# tagpass conditions are OR, not AND.
# If the (filesystem is ext4 or xfs) OR (the path is /opt or /home)
# then the metric passes
fstype = [ "ext4", "xfs" ]
# Globs can also be used on the tag values
path = [ "/opt", "/home*" ]
```
### Plugin Config: pass and drop
```toml
# Drop all metrics for guest & steal CPU usage
[[plugins.cpu]]
percpu = false
totalcpu = true
drop = ["usage_guest", "usage_steal"]
# Only store inode related metrics for disks
[[plugins.disk]]
pass = ["inodes*"]
```
### Plugin config: prefix, suffix, and override
This plugin will emit measurements with the name `cpu_total`
```toml
[[plugins.cpu]]
name_suffix = "_total"
percpu = false
totalcpu = true
```
This will emit measurements with the name `foobar`
```toml
[[plugins.cpu]]
name_override = "foobar"
percpu = false
totalcpu = true
```
### Plugin config: tags
This plugin will emit measurements with two additional tags: `tag1=foo` and
`tag2=bar`
```toml
[[plugins.cpu]]
percpu = false
totalcpu = true
[plugins.cpu.tags]
tag1 = "foo"
tag2 = "bar"
```
### Multiple plugins of the same type
Additional plugins (or outputs) of the same type can be specified,
just define more instances in the config file:
```toml
[[plugins.cpu]]
percpu = false
totalcpu = true
[[plugins.cpu]]
percpu = true
totalcpu = false
drop = ["cpu_time*"]
```
## Output Configuration
Telegraf also supports specifying multiple output sinks to send data to,
configuring each output sink is different, but examples can be
found by running `telegraf -sample-config`.
Outputs also support the same configurable options as plugins
(pass, drop, tagpass, tagdrop), added in 0.2.4
```toml
[[outputs.influxdb]]
urls = [ "http://localhost:8086" ]
database = "telegraf"
precision = "s"
# Drop all measurements that start with "aerospike"
drop = ["aerospike*"]
[[outputs.influxdb]]
urls = [ "http://localhost:8086" ]
database = "telegraf-aerospike-data"
precision = "s"
# Only accept aerospike data:
pass = ["aerospike*"]
[[outputs.influxdb]]
urls = [ "http://localhost:8086" ]
database = "telegraf-cpu0-data"
precision = "s"
# Only store measurements where the tag "cpu" matches the value "cpu0"
[outputs.influxdb.tagpass]
cpu = ["cpu0"]
```

InfluxDB.
## Plugin Options
## Configuration
There are 5 configuration options that are configurable per plugin:
* **pass**: An array of strings that is used to filter metrics generated by the
current plugin. Each string in the array is tested as a glob match against metric names
and if it matches, the metric is emitted.
* **drop**: The inverse of pass, if a metric name matches, it is not emitted.
* **tagpass**: tag names and arrays of strings that are used to filter metrics by the current plugin. Each string in the array is tested as a glob match against
the tag name, and if it matches the metric is emitted.
* **tagdrop**: The inverse of tagpass. If a tag matches, the metric is not emitted.
This is tested on metrics that have passed the tagpass test.
* **interval**: How often to gather this metric. Normal plugins use a single
global interval, but if one particular plugin should be run less or more often,
you can configure that here.

at 192.168.59.103:8086, tagging measurements with dc="denver-1". It will output
measurements at a 10s interval and will collect per-cpu data, dropping any
measurements which begin with `cpu_time`.

# PLUGINS
[plugins]
[[plugins.cpu]]

Below is how to configure `tagpass` and `tagdrop` parameters
```toml

# then the metric passes
fstype = [ "ext4", "xfs" ]
# Globs can also be used on the tag values
path = [ "/opt", "/home*" ]
```
Below is how to configure `pass` and `drop` parameters
```toml
# Drop all metrics for guest CPU usage
[[plugins.cpu]]
drop = [ "cpu_usage_guest" ]
# Only store inode related metrics for disks
[[plugins.disk]]
pass = [ "disk_inodes*" ]
```
Additional plugins (or outputs) of the same type can be specified,
just define more instances in the config file:
```toml

totalcpu = true
