This a a nagios/NRPE compatible plugin for checking docker containers. So far you can use it to check
- memory consumption in absolute units (bytes, kb, mb, gb) and as a percent of the container limit.
- automatic restarts performed by the docker daemon
- container status, i.e. is it running?
- uptime, i.e. is it able to stay running for a long enough time?
- image version (experimental!), does the running image match that in the remote registry?
This check can communicate with a local docker daemon socket file (default) or with local or remote docker daemons using secure and non-secure tcp connections.
This plugin requires python 3. It is tested on 3.3 and greater but may work on older versions of 3.
