Processes and Logs

SevOne NMS Processes

The Cluster Manager, at the Appliance level, the Process Overview tab displays the following list of processes SevOne NMS runs.

* Processes with an asterisk in the list and the following two processes (that do not appear in the list) can be monitored via the SevOne-NMS-MIB. This provides the ability to self monitor the SevOne NMS appliance. Self monitor statistics are available in Performance Metrics report attachments and Instant Graphs when you select the localhost device and its associated indicators on which to run reports.

  • SevOne-clusterd - Synchronizes communication among the appliances in a clustered environment.

  • SevOne-searchd - Indexes search results on the back end for the cluster wide advanced/global searches.

Processes are grouped into subsections. Some provide Stop, Start, and Restart buttons to enable you to stop and start processes. This is mainly for SevOne Support Engineers and you should not click these buttons without a strong cause.
