Linux and NonStop servers can be managed by the Performance Essentials SIM plug-in. A 
managed server has an agent to collect performance metrics. The agent keeps the latest 
performance snapshot of the server and reports this information back to the CMS 
component, when requested, through HTTPS interface. 
The HP NonStop Cluster Performance Essentials utilizes the cluster configurations managed 
by the Cluster Configuration Management application delivered with the HP NonStop Cluster 
Essentials product. The Cluster Configuration Management application lets the user create 
new clusters and define their members. It can also be used to edit or delete any existing 
cluster. The cluster configurations are stored in the SQL database on the CMS.
