The glusterpmd service is a Red Hat Gluster Storage process monitoring service running in every Red Hat Gluster Storage node to monitor glusterd, self heal, smb, quotad, ctdbd and brick services and to alert the user when the services go down. The glusterpmd service sends its managing services detailed status to the Nagios server whenever there is a state change on any of its managing services.

This service uses /etc/nagios/nagios_server.conf file to get the Nagios server name and the local host name given in the Nagios server. The nagios_server.conf is configured by auto-discovery.
