Chapter 17. Monitoring Red Hat Gluster Storage
Monitoring of Red Hat Gluster Storage servers is built on Nagios platform to monitor Red Hat Gluster Storage trusted storage pool, hosts, volumes, and services. You can monitor utilization, status, alerts and notifications for status and utilization changes.
For more information on Nagios software, refer Nagios Documentation.
Using Nagios, the physical resources, logical resources, and processes (CPU, Memory, Disk, Network, Swap, cluster, volume, brick, Host, Volumes, Brick, nfs, shd, quotad, ctdb, smb, glusterd, quota, geo-replication, self-heal,and server quorum) can be monitored. You can view the utilization and status through Nagios Server GUI.
Red Hat Gluster Storage trusted storage pool monitoring can be setup in one of the three deployment scenarios listed below:
- Nagios deployed on Red Hat Gluster Storage node.
- Nagios deployed on Red Hat Gluster Storage Console node.
- Nagios deployed on Red Hat Enterprise Linux node.
This chapter describes the procedures for deploying Nagios on Red Hat Gluster Storage node and Red Hat Enterprise Linux node. For information on deploying Nagios on Red Hat Gluster Storage Console node, see Red Hat Gluster Storage Console Administration Guide.
The following diagram illustrates deployment of Nagios on Red Hat Gluster Storage node.
