docker-prometheus-exporter

This docker exporter focuses on things not usually provided by cAdvisor

Currently it exports:

• health status of running containers as an enumeration: basically a gauge with values corresponding to container states.
  • 0 - n/a
  • 1 - starting
  • 2 - healthy
  • -1 - unhealthy
  • -2 - unknown health check state
• momentary max (across processes in a container) open file descriptors, useful if you did set limits on the container and want to keep an eye on it
