Exec Input Plugin
exec plugin executes the
commands on every interval and parses metrics from
their output in any one of the accepted Input Data Formats.
This plugin can be used to poll for custom metrics from any source.
[[inputs.exec]] ## Commands array commands = [ "/tmp/test.sh", "/usr/bin/mycollector --foo=bar", "/tmp/collect_*.sh" ] ## Timeout for each command to complete. timeout = "5s" ## measurement name suffix (for separating different commands) name_suffix = "_mycollector" ## Data format to consume. ## Each data format has its own unique set of configuration options, read ## more about them here: ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md data_format = "influx"
Glob patterns in the
command option are matched on every run, so adding new
scripts that match the pattern will cause them to be picked up immediately.
This script produces static values, since no timestamp is specified the values are at the current time.
#!/bin/sh echo 'example,tag1=a,tag2=b i=42i,j=43i,k=44i'
It can be paired with the following configuration and will be run at the
interval of the agent.
[[inputs.exec]] commands = ["sh /tmp/test.sh"] timeout = "5s" data_format = "influx"
Q: My script works when I run it by hand, but not when Telegraf is running as a service.
This may be related to the Telegraf service running as a different user. The
official packages run Telegraf as the
telegraf user and group on Linux
