A collectd plugin that taps in the Docker Stats API

What up? 👋

I'm Dustin, a software developer mainly writing Typescript, Go, and Rust (really loving Rust right now), but I find myself doing a bit of everything (or a lot...). I'm a big fan of Neovim, and working almost entirely in my terminal. I also spend way too much time scrolling GitHub Trending.

I've started blogging again to improve my writing skills, talk about existing projects or new ideas, and soon to go in to skills around management and tech leading.

collectd-docker-plugin's Issues

Output of script in /var/log/messages

Hey Dustin!

Thanks for your work on this plugin!

I was wondering if there is any way to silence the output of the script as it is filling /var/log/messages with tonnes of this:

I assume this is the answers from the calls to the API?

My set up is Centos 7 with docker versions:

[Feature request] Exclude some statistics

Collectd: 5.8.1
Collectd-docker-plugin: 0.4.0
Docker: 20.10.0

Thank you for this plugin. It's old but still working fine.

In the memory stats, I'm getting really big values for hierarchical_memory_limit. I think this is not fault of this plugin but it's making the chart unreadable. Could you add a way to exclude some statistics from your plugin like memory.hierarchical_memory_limit or something like that?

No Networking statistics available

Hello !

Thank you so much for this plugin, you have made an amazing job.
We are currently testing the plugin within Redhat Openshift clusters, and I realised that everything works perfectly except the network statistics which are not available,

For some reasons, collectd does not generate any network related metrics.

Testing this in Minishift works perfectly fine including networking stats, so I guess this could be related to the version of Openshift (or dockers) and/or custom parameters within the cluster.

Would you have any idea of what could happen ?

Or would there be a way to your collector in debug more and/or get any way of trouble shooting this ?

Thank you very much for your help!

Regards,

Guilhem

Please provide examples of using the parameters

Can you please provide an example of how to properly configure the plugin to use -w 1 or --wait-time 1?

I'd like to try the streaming version, but when I try:

LoadPlugin exec
<Plugin exec>
  Exec "mattymo:docker" "/usr/local/bin/collectd-docker-plugin" "-w 1" 
</Plugin>

Or

LoadPlugin exec
<Plugin exec>
  Exec "mattymo:docker" "/usr/local/bin/collectd-docker-plugin" "--wait-time 1"
</Plugin>

I get errors in /var/log/messages.

I am running this on Centos 7.
