The check plugin check_masifupgrader_agent monitors the Masif Upgrader agent, a component of Masif Upgrader.
Consult Masif Upgrader's manual on its purpose and the agent's role in its architecture.
The binaries of the Debian packages take the following CLI arguments and no environment variables:
$ /usr/lib/nagios/plugins/check_masifupgrader_agent \ -restsock /var/run/masif-upgrader-agent/rest.s \ [-resptime-(warn|crit) THRESHOLD] \ [-(query|install|update|configure|remove|purge|error)-(1m|5m|15m)-(warn|crit) THRESHOLD]
THRESHOLD specifies an alert threshold range
conforming to the Nagio$ check plugin API,
-error-5m-warn @~:42 warns if there occurred <= 42 errors
during the last 5 minutes.
To print the legal info, execute the plugin in a terminal:
In this case the program will always terminate with exit status 3 ("unknown") without actually checking anything.
If you want to actually execute a check inside a terminal, you have to connect the standard output of the plugin to anything other than a terminal – e.g. the standard input of another process:
$ /usr/lib/nagios/plugins/check_masifupgrader_agent |cat
In this case the exit code is likely to be the cat's one. This can be worked around like this:
bash $ set -o pipefail bash $ /usr/lib/nagios/plugins/check_masifupgrader_agent |cat
Just integrate the plugin into the monitoring tool of your choice like any other check plugin. (Consult that tool's manual on how to do that.) It should work with any monitoring tool supporting the Nagio$ check plugin API.
- check_masifupgrader_agent must be run on the host to be checked – either with an agent of your monitoring tool or by SSH. Otherwise it will check the host your monitoring tool runs on.
- The user check_masifupgrader_agent runs as must be a member
of the group masif-upgrader-agent, i.e.:
usermod -aG masif-upgrader-agent nagiosDon't forget to restart your monitoring tool's service if any.
