Language-agnostic Plugins

[trehn]

Does Telegraf plan to allow users to write plugins in any language? Being able to quickly write something in Bash or Python would probably make a lot of ops people happy. Quite often I only need to collect a measurement once an hour or so, so the extra overhead would not be an issue at all.

Maybe this could be implemented as a plugin that just runs a configured list of commands with some configuration in env vars.

It could also be nice to be able to specify a different duration between poll for each plugin.

@atmaniak you can do that already, check out Interval under https://github.com/influxdb/telegraf#plugin-options

@trehn It certainly could be implemented via an exec plugin that takes a list of programs to run. If they output JSON to stdout it should be easy enough to allow them to pass any number of values back as well.

Hello

@evanphx is it possible to use an unix socket to do communication between differents langages ? I think it is a good way to have an universal plugin to gather metrics ?
The problem is for other environnement like windows... but for the moment I use it under MacOS and Linux.

If you like the idea, i could do a pull request about it.

Best regards,
Nicolas

Sounds like a good idea, marking it as an enhancement request
