## Generating a Configuration File
|
||||
|
||||
A default Telegraf config file can be generated using the `-sample-config` flag,
|
||||
like this: `telegraf -sample-config`
|
||||
A default Telegraf config file can be generated using the -sample-config flag:
|
||||
`telegraf -sample-config > telegraf.conf`
|
||||
|
||||
To generate a file with specific inputs and outputs, you can use the
|
||||
`-input-filter` and `-output-filter` flags, like this:
|
||||
-input-filter and -output-filter flags:
|
||||
`telegraf -sample-config -input-filter cpu:mem:net:swap -output-filter influxdb:kafka`
|
||||
|
||||
## Telegraf Agent Configuration
|
||||
## `[tags]` Configuration
|
||||
|
||||
Global tags can be specific in the `[tags]` section of the config file in
|
||||
key="value" format. All metrics being gathered on this host will be tagged
|
||||
with the tags specified here.
|
||||
|
||||
## `[agent]` Configuration
|
||||
|
||||
Telegraf has a few options you can configure under the `agent` section of the
|
||||
config.
|
||||
|
||||
* **hostname**: The hostname is passed as a tag. By default this will be
|
||||
the value returned by `hostname` on the machine running Telegraf.
|
||||
You can override that value here.
|
||||
* **interval**: How often to gather metrics. Uses a simple number +
|
||||
unit parser, e.g. "10s" for 10 seconds or "5m" for 5 minutes.
|
||||
* **debug**: Set to true to gather and send metrics to STDOUT as well as
|
||||
InfluxDB.
|
||||
* **interval**: Default data collection interval for all inputs
|
||||
* **round_interval**: Rounds collection interval to 'interval'
|
||||
ie, if interval="10s" then always collect on :00, :10, :20, etc.
|
||||
* **metric_buffer_limit**: Telegraf will cache metric_buffer_limit metrics
|
||||
for each output, and will flush this buffer on a successful write.
|
||||
* **collection_jitter**: Collection jitter is used to jitter
|
||||
the collection by a random amount.
|
||||
Each plugin will sleep for a random time within jitter before collecting.
|
||||
This can be used to avoid many plugins querying things like sysfs at the
|
||||
same time, which can have a measurable effect on the system.
|
||||
* **flush_interval**: Default data flushing interval for all outputs.
|
||||
You should not set this below
|
||||
interval. Maximum flush_interval will be flush_interval + flush_jitter
|
||||
* **flush_jitter**: Jitter the flush interval by a random amount.
|
||||
This is primarily to avoid
|
||||
large write spikes for users running a large number of telegraf instances.
|
||||
ie, a jitter of 5s and flush_interval 10s means flushes will happen every 10-15s.
|
||||
* **debug**: Run telegraf in debug mode.
|
||||
* **quiet**: Run telegraf in quiet mode.
|
||||
* **hostname**: Override default hostname, if empty use os.Hostname().
|
||||
|
||||
