Hi!
Please check out the “metric_info” definitions in ~/lib/python/cmk/gui/plugins/metrics/check_mk.py, e.g.:
metric_info[“mem_used_percent”] = {
“color”: “#80ff40”,
“title”: _(“RAM used %”),
“unit”: “%”,
}

You can make your own definitons and put them into a file “blahblah.py” located in ~/local/share/check_mk/web/plugins/metrics. Make sure to include the imports of the stuff you use in the file’s header, as done in ~/lib/python/cmk/gui/plugins/metrics/check_mk.py.
Into this file, you can also put graph_info definitions, if you want to combine multiple metrics into one graph.

Have fun!
Lars

Hi Lars

Thanks for the reply .
i m using centos7 for running plugin . and i m using a shell script right now for this purpose .
i dont see path ~/lib/python/cmk/gui/plugins/metrics/ on centos7
currently i have written shel script in /usr/lib/check_mk_agent/local/mylocalcheck.sh
where i m simply passing
echo “P $processname count1=28;30;40|count2=21;23;27|count3=66;65;70 OK - This is my custom output”

Hi!

You have to do these changes as CMK site user. That user has its home in
/opt/omd/sites//, so the path I was referring to above, is:
/opt/omd/sites//lib/python/cmk/gui/plugins/metrics/check_mk.py resp. /opt/omd/sites//local/share/check_mk/web/plugins/metrics.
Please only change files below /opt/omd/sites//local, otherwise you might damage your CMK installation.

Regards
Lars

Hi Lars

can you please give me some example , that will help

Hi!

You will find all the examples in ~/lib/python/cmk/gui/plugins/metrics/check_mk.py, e.g. the “license” metrics absolutely fit to your local check, as the contain “%”, “count” and “bytes”:

"title": _("Used licenses"),
"unit": "%",
"color": "16/a",

}

metric_info[“licenses_total”] = {
“title”: _(“Total licenses”),
“unit”: “count”,
“color”: “16/b”,
}

metric_info[“license_size”] = {
“title”: _(“Size of license”),
“unit”: “bytes”,
“color”: “11/a”,
}

Take these lines, replace “license_percentage” with “count2”, and so on. Then, do an “omd restart apache” and check out your new metrics.

Lars
