What's the exact query you're running? Documentation around those results is a bit sparse. For service/host status mappings, those can be found here: https://github.com/NagiosEnterprises/nagioscore/blob/345fd4e8257085ce7f3806ee4fb04008919f24e5/include/statusdata.h#L143-L159 Many of those fields, lik...

Does the nagios user have perms to run Rscript ? Also to import the webshot library? A pretty common gotcha with R is that the user is completely unable to bring in certain libraries to the R runtime due to perms errors. I would suggest hard-coding the path to your Rscript binary, as Nagios Core doe...

However when the nagios user is called, it ignores the environment variables configured in bash.bashrc and profile.d/appenv.sh. Commands executed by NRPE do not run in a shell -- Bash or otherwise. They are executed via popen . They therefore do not inherit environment variables defined in a partic...

It was designed to be...

What OS and version of that OS are being used on this machine? Sounds like one of your mounts is set to read-only for one reason or another.

What is the output of the following command, executed from the CLI of your Nagios Core machine:

Code: Select all

What agent is being used on the Windows machine? NSClient++ and NCPA are the two most common. This documentation covers leveraging a Nagios event handler with NSClient++: https://assets.nagios.com/downloads/nagiosxi/docs/Restarting-Windows-Services-With-NRPE-in-Nagios-XI.pdf The documentation mentio...

Nagios XI is by far the most feature-rich one. In the "more free" space, NagiosQL and NConf are the 2 big ones. Both of which could definitely use some more maintainers :) which is the story for most free front-ends for Nagios Core. I've not used Lilac , but it looks basically OK. I prefe...
