HP Insight Control for Linux 6.2 User Guide

Nagios, as provided with Insight Control for Linux, is configured with system and network
service checks already in place for your system; these network service checks are automatically
configured for each managed system.
Nagios obtains its sensor and metric data from the Supermon open source monitoring application,
which is integrated with the Insight Control for Linux.
Figure 20-1 illustrates the interaction of these tools.

The mond and syslog daemons run on every managed system. The Supermon service manages
requests for mond daemons that run on a subset of systems. The Nagios master runs its
check_metrics plug-in periodically, which causes Supermon data collection and storage into
the database. The syslog daemons on the managed systems report events to the syslog-ng
service. The managed systems are configured to forward their syslog events to the syslog-ng
service on the CMS
