Nagios Support Forum

I'm trying to install the graph Explorer on an evaluation version of Nagios XI version 2011R2.2. I was given access to the graph Explorer for evaluation purposes as well. This is great, but unfortunately the graph explorer will not install

When I try to add the graph Explorer using "manage components" in "Admin", I get the message "Component installed" when I upload the component, but it won't show up in the component overview. I installed other components this way and both showed up afterwards.

I tried with both my own account (which has admin rights) and the NagiosAdmin account. This makes no difference. I haven't cleared the browser cache as was sugested, but I tried on a different machine with two browsers, neither will show the graph explorer.

Are there any files located in the following directory on the VM?

/usr/local/nagiosxi/html/includes/components/graphexplorer

Yes, the same files that are in the graphexplorer.zip show up in that directory.

Are you sure you are looking for the right name, it displays as "Nagios graph Explorer", also you should see "graph Explorer" under
Home -> Performance graphs

I just tested it under a 2011R2.2 and it installed just fine.

If yo still don't see it, you may need to check your httpd error log to see if you can see anything

I'm sure I looked for the correct name. I only saw the Host graphs and not the graph Explorer.

In the logfile a number of errors came by.

Looking at the installed files revealed that the graph explorer was installed as nagios.users. When I changed owership to the nagios group the explorer showed up in the menu and is now useable.

What linux distro are you on, and do your systems have any umask settings in place as a security policy?

Distribution used is CentOS release 6.2 (Final)
umask 002

Many installers expect the stock umask 0027.

This was likely causing the problem.

graph Explorer works since I changed the group to Nagios instead of user so no more problems there. Thanks for that.

I did some more tests, I installed the "Custom Logo" component. It is installed with the same rights as the graph explorer, but works immediately and shows a custom logo now. So the behavior of that component is not entirely consistent with the graph explorer component.

Yes, it kind of depends on what the component does, some need to be able to just read, some write, some execute...
