Hi,

How large is the check load on this system, total number of hosts and servers? The time it takes for nagios to populate all your hosts and services in the DB after restarting nagios is really dependent on how fast the database server can run all the queries (tens of thousands).

Can you post the database log or send over a system profile, to check the database logs for any errors.

Implementing a RAM disk can help improve the overall speed.

Also, take a look at the following guide for overall recommendations to improve performance.

Hi,

Overall the system profile looks pretty good but I did notice a couple of things to correct. In the command subsystem log, I'm seeing the following error:

Code: Select all

PROCESSED 0 COMMANDS
MIB search path: /home/nagios/.snmp/mibs:/usr/share/snmp/mibs
Cannot find module (EtherLike-MIB): At line 0 in (none)
Cannot find module (SNMP-USER-BASED-SM-MIB): At line 0 in (none)
Check the permissions or names on those files in the following directly, it's unable to read them.

Code: Select all

ls -al /usr/share/snmp/mibs
It should like something like this:

Code: Select all

[root@localhost ~]# ls -al /usr/share/snmp/mibs | grep EtherLike-MIB
-rw-rw-r--. 1 root nagios  84492 Nov 25  2019 EtherLike-MIB.txt
There's fatal PHP error in the Apache logs.

Code: Select all

PHP Fatal error:  Call to a member function xpath() on a non-object in /usr/local/nagiosxi/html/includes/components/graphexplorer/visFunctions.inc.php on line 554, referer: http://x.x.x.222/nagiosxi/dashboards/dashboard.php?id=u0J9shnQ
There's a graph explorer dahslet that is not pulling the graph correctly. Do you notice any dashlets to populating correctly? If so, please try to remove those. You can pull up this dashboard using the URL.

Code: Select all

http://x.x.x.222/nagiosxi/dashboards/dashboard.php?id=u0J9shnQ
Overall, this is not too big of a system so it should take more a couple minutes to Apply Configuration.
