SYMON FOR EMC CENTERA

The SYMON Monitoring Plugin for EMC Centera monitors cluster nodes, disks, and network connections, as well as local and remote replication performance in the clusters. By monitoring a large amount of detailed information, the handling of system capacities is significantly simplified. The plugin uses the CentraViewer for data collection.

The SYMON Monitoring Plugin for Centera consists of a data collector (centera-collector) and various checks for different components of the EMC Centera system. The collector of the SYMON Monitoring Plugin for Centera defines the checking interval. If you want to check certain components every 15 minutes, you have to set the checking interval of the collector to 15 minutes. The checking interval has to be the same for all components, meaning it must be set at the interval of the component with the shortest desired checking interval.
