Nagios XI - Core 4 Load Spikes on 1.75 and 7 Hour Intervals

Problem Description

With the release of Nagios XI 2014 the core version on the back-end was updated to Core 4. This introduced a issue in certain environments where an extremely high system level load can occur at intervals most commonly between an hour and seven hours of the Nagios process starting.

Resolving The Problem

As a temporary solution to this we recommend that if you have been experiencing this problem, you should modify:

/usr/local/nagiosxi/html/config.inc.php

By changing the following line:

"nom_checkpoint_interval" => 1440, // time (in minutes) between nom checkpoints

To:

"nom_checkpoint_interval" => 90, // time (in minutes) between nom checkpoints

 

You may want to alter the above noted interval based on when you are experiencing these problems.

Ideally it should be set to occur as close to the high load anomaly as possible as to minimize system downtime and stress while we work towards a more permanent solution.

This will force the creation of a snapshot, so you may want to archive any important config snaphots as these changes will increase the number of daily snapshots (possibly pushing needed snapshots from the pool).
