Nagios XI - MK Livestatus Problems With Mod-Gearman

Warning: Mod-Gearman is an unsupported third-party utility.

Nagios Enterprises provides this KB article to customers in good faith. However, an attempted integration with Mod-Gearman is not supported by Nagios Enterprises and future problems caused by using this method are beyond our control.

Multiple Nagios XI instances can be used if the size of your infrastructure or monitoring needs require you to create a distributed monitoring environment. Federated or distributed Nagios XI instances empower you to scale your infrastructure while making it easier to manage large environments and future changes. For more information on using multiple Nagios XI instances to distribute check load, visit Distributed Monitoring with Nagios XI.

Problem Description

It has been observed that when you use the combination of Nagios Core 4 + Mod-Gearman + MK Livestatus, nagios can segfault on passive check results.

The issue is with MK Livestatus used in this combination.

The following combinations are reported to work fine:

  • Nagios Core 4 + Mod-Gearman
  • Nagios Core 4 + MK Livestatus
