SYMON FOR EMC ISILON

The SYMON Monitoring Plugin for EMC Isilon monitors the status of a complete Isilon cluster. It checks the hardware status of the different components of each node. It also monitors the utilization rate of the nodes, which may trigger an alert in the event of one-sided loading. The plugin connects to the system via REST (https) and thus does not require any special tools or additional ports.

CHASSIS TEMPERATURE:Checks all Nodes for temperature Values.
The architecture is based on an active/passive concept. There are active checks with a binary to execute. The active check connects to the storage and collects all the data, that is needed. It then checks whether a passive check is set up for all discovered components in the configuration. If this is the case, the passive check is updated with the status information. If no passive check is found, an example configuration will be saved under /tmp/check_avamar/avamar_alt.cfg and the main collector check will issue a warning to inform about configuration changes. The check_freshness binary, which is executed if a passive check did not receive new status information for a longer period of time, is included in all passive checks. This concept allows a resource-efficient operation and gives the plugin the possibility to discover the configuration automatically.
