No Activity in Monitoring Engine Event Queue After Reboot

[mcwhorts]

Linux Distribution and version?
CentOS release 6.9 (Final)
32 or 64bit?
64bit
VMware Image or Manual Install of XI?
Manual Install

So we recently did some OS patching. I've attached a list of those patches. After the patch, the VM was rebooted. Everything seemed fine till we discovered the next day that there was no activity in Nagios. The event log showed no activity after the reboot as well as the monitoring engine event queue. I could use a hand troubleshooting this. Thanks

when I run service nagios start, I get the following

Running configuration check...

Nagios Core 3.5.1

Reading configuration data...
Error in configuration file '/etc/nagios/nagios.cfg' - Line 309 (UNKNOWN VARIABLE)
Error processing main config file!

So I look to see what it's referencing on line 309 of /etc/nagios/nagios.cfg which is this

log_current_states=1

If I comment that out and try service nagios start it seems to work.

sudo service nagios restart
Running configuration check...
Stopping nagios: done.
Starting nagios: done.

I forgot to mention that the problem with the monitoring engine still persists.

Running configuration check...

Nagios Core 3.5.1

This is not the correct version of nagios for a 5.4.10 nagios XI installation, my guess is you install nagios core from RPM, run this to check

Code: Select all

rpm -q nagios

if you get something as a result we need to remove this package

Code: Select all

yum remove nagios

Then you will need to run the following to install the correct version

Code: Select all

cd /tmp
rm -rf nagiosxi xi* /etc/init.d/nagios
wget https://assets.nagios.com/downloads/nagiosxi/xi-latest.tar.gz
tar xzf xi*.tar.gz
cd /tmp/nagiosxi/subcomponents/nagioscore/
./install

Once this completes, lets try starting nagios

Code: Select all

service nagios start

Installing the correct version of nagios core fixed the problem. Thanks for your help.

Glad that you got this resolved with installing the new version of Nagios Core!
