  • Disk performance
  • Load average
  • Memory used/free/etc
  • Uptime
  • Network interface
  • Swap

Environment variables

  • HOST_NAME
    • Will be sent to Graphite
    • Required
  • GRAPHITE_HOST
    • Graphite IP or hostname
    • Required
  • GRAPHITE_PORT
    • Graphite port
    • Optional, defaults to 2003
  • GRAPHITE_PREFIX
    • Graphite prefix

docker-collectd-write-graphite's Issues

How to turn on plugins?

Are there any ways to switch on other plugins?

What about to add to your collectd.conf.tpl few lines:

<Include "/etc/collectd/collectd.conf.d">
        Filter "*.conf"
</Include>

and map volume to directory /etc/collectd/collectd.conf.d/ so we could add *.conf files in it and manipulate with collectd?

unable to get collectd image to write to graphite

I am not sure this is the right place to ask for help with images. if not can you please, tell me where to do so?

hi, i am trying to get your collectd image working on a mac. i have got a shell into the image and used envtpl to generate a collectd.conf in /etc/collectd/collectd.conf

also, i was trying to make this image work with another graphite image, 'hopsoft/graphite-statsd' and graphite listens on 2003/tcp so I was trying to modify collectd.conf to specify Protocol as per https://collectd.org/wiki/index.php/Plugin:Write_Graphite but it does not work as collectd complains Protocol is not a valid configuration.

write_graphite plugin: Invalid configuration option: Protocol
