1.Introduction
The HP NonStop Cluster Performance Essentials software provides plug-in components to HP
Systems Insight Manager (SIM) to support performance monitoring of heterogeneous
clusters consisting of a combination of NonStop™ and Linux servers. The software allows a
user to monitor the performance of Linux and NonStop clusters or individual servers using
the HP SIM interface.
Product overview: HP NonStop Cluster Performance Essentials is comprised of the
following
 Performance Essentials HP SIM Client (PE SIM Plug-in)
 Performance Essentials NonStop Host (NonStop Agent)
 Performance Essentials Linux Host (Linux Agent)
The Performance Essentials SIM plug-in to HP SIM runs on the Central Management Server
(CMS) and the agents run on NonStop and Linux servers. Performance Essentials agent
components provide the collection and routing of performance metrics from the managed
servers to the Performance Essentials SIM plug-in. This enables the performance monitoring
of the servers from the CMS using server-specific performance data. Agent software runs on
each managed NonStop or Linux server in association and in support of the SIM plug-in
component. Together, they are responsible for gathering performance metrics from
managed NonStop and Linux servers in the clusters, representing them in the HP SIM GUI,
determining the status of clusters periodically, and providing alert notifications based on
user-defined thresholds.
