Ever since the last upgrade 1.8 i am getting lots of errors in the http files and also sometimes it just wont connect to the central.

Some of the errors include:

Some other errors include bad requests or missing css files etc. I will try to add those when i get them later on.

I think this might be related to SSL with the Nagios cgi's. Can you check to see if you're set to the following config in /usr/local/nagios/etc/cgi.cfg?

Code: Select all

use_ssl_authentication=1

I just checked and it seems that wasn't set to 1. I changed it now so lets hope that fixes it :)

It seems it didn't matter.

I am still getting lots of errors in the httpd file. What is worse is that the network status map stopped working for some reason.

My bet is that the network status map stopped working from the change I suggested in the cgi.cfg file. Go ahead and switch it back for now. I'm pretty sure there's an SSL certificate issue there, and I'm guessing it's probably related to the apache settings for the /nagios alias. However, we'll have to test in our SSL environment and see if we can figure out where that might be going wrong. Just to verify, did you set up your SSL according to our doc?

That setting fixed it.

For most part i did use the settings as supplied in your docs but the change i made is i used 1 cfg file instead of 10 loose ones. This was so i could get nrdp to work.

a full printout of the cfg is as follows:

Code: Select all

I noticed something else on the status map aswell. Even though it looks like its working i still have the errors in the httpd log and for some reason it wont update the icons on some of the hosts. I tried changing the names to others but even there it wont help a thing.

[EDIT]
Well i got some more info. It seems the status map is completely static by now. Even if i add a host/service or change any of the hosts with icons nothing will change. Errors that i get when i do a tail command are:

It worked fine before but today it just stopped working. The only thing i did was add the history component and the custom logo one.

I'll have to do some testing and see if I can recreate this issue. I'm not really sure what the source of the issue is.

If it helps we can do a remote session so you can see the problems and perhaps the solutions.

I just retested the SSL setup according to our documentation on 1.8, and so far everything is working fine, and the network status map is displaying both maps ok. I even closed port 80 just to be safe. I'll look through your apache configs and compare them to what I've got, I'll see if that turns anything up.
