Nagios Support Forum

Thanks for posting this! Now that you mention it I had seen other users who made this change and it fixed their graphs, but it wasn't a consistent problem so we didn't get it documented. I'm going to add this to our Wiki.

Thanks!

I get "You don't have permission to access /nagios/pnp/ on this server."
See attached jpeg.

Anything else for me to try? I need to get this running.
How about any comments on my previous questions?

Thanks...Lyle

Hey Lyle,

Have you checked to see if you have the same issue going as user lomartin? Have you tried the following fix?

* Some users reported that editing the following lines in their /usr/local/nagios/etc/nagios.cfg file fixed their graphing issues:
Change To

I changed the 2 config lines as suggested and did a "service nagios restart", but I still have the problem.

Thanks...Lyle

Hello, XI Support:

I'm willing to try anything on this issue. But I need to get it solved. Your suggestions are appreciated.

Some of my previous questions on this issue may be off-base, but I'm just trying to understand the system better so I can help solve the problem.
Here's a list of my previous questions that have gone unanswered:

• ?? If there's any question about the plug-in adhering to the guidelines, the "check_nrpe!check_load" command is running the check_load plugin from your nrpe distribution. But I'm happy to try any plugin you suggest
  
  ?? I'd be happy to check through the logs, but I'm not sure which ones to check and for what. Is there any documentation on what logs are what?
  
  ?? Is there any documentation I can read to tell me how all this goes together? RRDTool, PNP, XI, etc? I wish I understood who is parsing the messages returned by nrpe, who updates rrdtool with the data, which logfile logs this activity, and who graphs the result when XI ask for it.
  
  ?? When the XI web interface requests a graph, should it result in a file I can see in the filesystem somewhere?
  
  ?? Is there any log of this process? Can I up the debugging level to see it better?
  
  ?? How would I generate a graph by hand?
  
  ?? Anything else for me to try? I need to get this running. How about any comments on my previous questions? (a recursive query)

Thanks...Lyle

Hey Lyle,

Lets look at trying to set up a remote session. Details are in a private message for you.

I'm having what appears to be the same issue. Would ya'll mind keeping me updated with this also?

Thanks

Will do. We updated our wiki with any known solutions for performance graph problems. If you haven't already go ahead and take a look at those as well.

Update -
I can view the charts on the nagios server itself, but still not remotely (from several different machines)

The security guys here are looking into it to see if it's something on their end.

The SOC is not seeing any denies from our nagios server. However, they did suggest checking the httpd error_log, and I'm getting spammed by this:

[Thu Mar 17 10:24:18 2011] [error] [client 127.0.0.1] PHP Warning: include_once(/usr/local/nagiosxi/html/includes/components/snmpwalk/../configwizardhelper.inc.php) [<a href='function.include-once'>function.include-once</a>]: failed to open stream: No such file or directory in /usr/local/nagiosxi/html/includes/components/snmpwalk/snmpwalk.inc.php on line 8, referer: http://localhost/nagiosxi/includes/comp ... &dest=auto

I'm getting that message every 5 minutes for every browser window looking at nagios on every host.

This error may not be related, but it's all I'm finding right now.
