Chapter 1. Introduction

Nagios Core is an open source solution for monitoring hosts. Large Ceph Storage clusters benefit from distributed monitoring systems such as Nagios Core that check each host in a cluster, including the health of the underlying operating system, as well as the health of the Ceph Storage Cluster daemons.

To deploy Nagios Core with Ceph requires:

  • A running Ceph cluster.
  • A running Nagios core server.

In lieu of Nagios Core, you may also substitute the more feature rich commercial version, Nagios XI.
