Auto-discovery creates folders and files as part of configuring Red Hat Gluster Storage nodes for monitoring. All nodes in the trusted storage pool are configured as hosts in Nagios. The Host and Hostgroup configurations are also generated for trusted storage pool with cluster name. Ensure that the following files and folders are created with the details described to verify the Nagios configurations generated using Auto-discovery.
- In
/etc/nagios/gluster/directory, a new directoryCluster-Nameis created with the name provided asCluster-Namewhile executingconfigure-gluster-nagioscommand for auto-discovery. All configurations created by auto-discovery for the cluster are added in this folder. - In
/etc/nagios/gluster/Cluster-Namedirectory, a configuration file,Cluster-Name.cfgis generated. This file has the host and hostgroup configurations for the cluster. This also contains service configuration for all the cluster/volume level services.The following Nagios object definitions are generated inCluster-Name.cfgfile:- A hostgroup configuration with
hostgroup_nameas cluster name. - A host configuration with
host_nameas cluster name. - The following service configurations are generated for cluster monitoring:
- A Cluster - Quorum service to monitor the cluster quorum.
- A Cluster Utilization service to monitor overall utilization of volumes in the cluster. This is created only if there is any volume present in the cluster.
- A Cluster Auto Config service to periodically synchronize the configurations in Nagios with Red Hat Gluster Storage trusted storage pool.
- The following service configurations are generated for each volume in the trusted storage pool:
- A Volume Status - Volume-Name service to monitor the status of the volume.
- A Volume Utilization - Volume-Name service to monitor the utilization statistics of the volume.
- A Volume Quota - Volume-Name service to monitor the Quota status of the volume, if Quota is enabled for the volume.
- A Volume Self-Heal - Volume-Name service to monitor the Self-Heal status of the volume, if the volume is of type replicate or distributed-replicate.
- A Volume Geo-Replication - Volume-Name service to monitor the Geo Replication status of the volume, if Geo-replication is configured for the volume.
- In
/etc/nagios/gluster/Cluster-Namedirectory, a configuration file with nameHost-Name.cfgis generated for each node in the cluster. This file has the host configuration for the node and service configuration for bricks from the particular node. The following Nagios object definitions are generated inHost-name.cfg.- A host configuration which has Cluster-Name in the
hostgroupsfield. - The following services are created for each brick in the node:
- A Brick Utilization - brick-path service to monitor the utilization of the brick.
- A Brick - brick-path service to monitor the brick status.
