PNP from Nagios XI GUI

I am using the check_multi plugin to monitor some SaaS services. The way that the performance data is captured is incompatible with the performance charts in Nagios XI but work find in PNP4Nagios.

Is it possible to add a link or icon with a link to the pnp graphs or even a new tab within the "Service Status Detail" page?

This is something the devs would need to do, but I doubt they will since we have the capability to use either PNP or Highcharts for graphing. Under Admin, go to System Settings and then uncheck the "
Use Highcharts for Perfdata Graphs" box, and save the settings. This will revert to using PNP for graphs, albeit on a global scale.

Thanks tmcdonald for the information. Updating the settings to use PNP does not display the graphs from check_multi only the perf data for check_mulit commnad itself and not the embedded checks.

Can you show us the actual check run from the command line, along with the output of it? Also, show a screenshot of the "Advanced" tab page. Thanks!

I asked the devs about this, and we use
:: in some places as a delimiter. As your perfdata output contains that sequence in a few places, it is likely causing issues with our templating. It might be possible to write a wrapper script around check_multi that will escape the
:: sequence to
\:\: but I have not tested this. Are you decent with bash scripting? I don't have the time right at this moment, but if you can write it yourself that's great otherwise I could ask another tech if they would be willing.
Edit: To address your original point, the Actions Component can add links to the page:
https://assets.nagios.com/downloads/nag ... ponent.pdf
Edit 2: Or the check_multi plugin has some options that can affect perfdata:

See option 32

If someone else could help that would be great.

Try modifying your command by adding "-r 32" to it.
Code: Select all
./check_multi -f /opt/tools/nagios/libexec/multi_check/website_heartbeat.cmd --s WARN=4000 --s CRITICAL=14000 --s SITE=freescale.sciforma.net -r 32
Remove the rrd & xml files from "/usr/local/nagios/share/perfdata/<hostname>/". Wait for 20-30 min. The perfdata should start showing up.
I tried the following command:
Code: Select all
check_multi!-f /usr/local/nagios/libexec/check_multi.cmd -r 32
My graph looks goofy as I have tons of checks...
but hichart graphs do work.

I saw the -r 32 options but I loose where the check was done. In my case I am using multi_check to check SaaS web services throught servers around the globe so I need to show which region the perf data is from.

I see. In this case, you can try the following workaround. Make a backup of the original "check_multi" plugin.
Code: Select all
cp -p check_multi check_multi_backup
Open the plugin in a text editor, and modify the following lines (around 3890 - 3900) from this:
Code: Select all
printf "$delim%s::%s::plugins$delim=%d time=%f ",
to this:
Code: Select all
printf "$delim%s-%s-plugins$delim=%d time=%f ",
and this:
Code: Select all
printf "$delim%s_extended::check_multi_extended::count_ok$delim=%d count_warning=%d count_critical=%d count_unknown=%d overall_state=%d ",
to this:
Code: Select all
printf "$delim%s_extended-check_multi_extended-count_ok$delim=%d count_warning=%d count_critical=%d count_unknown=%d overall_state=%d ",
Note: Basically, you are substituting "::" with "-".
Remove the old rrd & xml files and wait for them to get recreated. Check your graph in about 30 min.
Did this help?
