Nagios Support Forum

Hello,
I have applied the latest patch and although it is no where near as slow as what it was, some panes are still not showing the correct data after time. The initial refresh is much faster, but still after some hours not all the data is visible in Xi, but visible in Nagios3.2.

Any ideas ?

Can you run the following tool and post the output from it?

Hmm, what types of services are the ones that seem problematic? I am trying to find a common thread here between those that are not working. Could you post any information (minus any private company info of course) to help us try and tie some things together?

HI All,

Here is the output from the nagios Stats cmd.

I am gathering more information in regards to specific checks. Early investigation shows that it is a bit random.

Another interesting thing i found was when using the Config wizards, I was not able to see any data relating to Hostgroup configurations.

I have noticed this in my nagios.log file.

The only thing is I do believe I was seeing this before I did the upgrade. Have you seen this before?

You might have a broken or corrupted mysql table. Can you try the following script and see if the situation improves?

/usr/local/nagiosxi/scripts/repairmysql.sh nagios *


I think those errors in your log are definitely the key, I'm just not sure yet where the issue is coming from. Your nagiostats look good, nothing indicating overloading your system at all, so the problem must be something related to ndoutils.

Hi, I ran the command and it did seem to make a difference. but I am still not seeing the hostgroup information when I am using the config wizards. Also when i did a new import of configs from my old system I had the same problem again with it taking a long time to refresh.

I have rolled back my system to Xi 2009 1.4

I know I should have put this in my first post. but my system specs are
RHEL 5 - 32bit Vmware Guest with 8gb of memory
DNX with two worker nodes also 32bit.

Thanks

Hi, I ran the command and it did seem to make a difference. but I am still not seeing the hostgroup information when I am using the config wizards.

Is with any particular wizard, or all of them?
When you run the wizard, can you also run a
tail -f /var/log/httpd/error_log
and watch for errors when that page loads up? (I know you'll probably get several notices and warnings, but send us anything that looks like it might be relevant).

Also when i did a new import of configs from my old system I had the same problem again with it taking a long time to refresh.

Are you referring to the data in the XI interface? Could you elaborate on this a bit more? I'm not quite following what this is referring to, and I want to make sure I understand the issue.

How is your nagios.log looking after the repair script for the mysql tables? Have the mass error messages for ndoutils gone away?

Hello,
Sorry for not replying for some time, but I have been busy solving problems. I have resolved this problem.
We have several older oracle databases in our organisation and in order to check them using nagios an Oracle 9i client had to be installed. This overwrote the existing version of gcc to version 3.4 or something old. Although no compilation errors occured when upgrading this seemed to have a large impact with NDOUtils not working properly. ofcourse because it was not Yum that installed the older version of gcc it still thought that it was at the latest version.

I know this would not occur with most people, but could I suggest some version checks to be performed on compilers as part of the pre-reqs?

Thanks again for your assistance in the matter

Rob

Hello Rob,
thanks for the update and we are glad you figured that out. That is an excellent suggestion as information such as this helps us to develop our products.
