- this repository contains a Icinga / Nagios plugin to monitor HAProxy (via the stats socket file)
- Written for python3
- No additional python modules required, only uses modules from the Python Standard Library
- I've tested this plugin with various HAProxy versions from 1.X to 2.X
- This plugin offers two check modes
--mode instance (default)
- Checks the whole HAProxy instance
- If all backend servers are
UP
- If any of the backend servers is getting close to it's session limit
- If all frontends are
OPEN
- If any of the frontends is getting close to it's session limit
- If all backends are
UP
- If any of the backends is getting close to it's session limit
--mode frontend
- Checks single HAProxy frontend
- If the specified frontend is
OPEN
- If the specified frontend is getting close to it's session limit
usage: check_haproxy.py [-h] [--socketfile SOCKETFILE] [--mode {instance,frontend}] [--slimwarn SLIM_WARN] [--slimcrit SLIM_CRIT] [--frontend FRONTEND]
