Monitoring Strategy

The HP XC system monitoring strategy is built on Open Source tools that are configured automatically to provide a seamless integration with the HP XC system. The key open source components of the monitoring suite consist of the following:

The syslog-ng tool provides consolidated logging across the HP XC system. The supermon tool allows metrics to be gathered efficiently throughout the HP XC system and aggregated into the Configuration and Management database (cmdb). Nagios provides dynamic health monitoring and reporting as well as integration of the various monitoring services. Figure 6-1 illustrates the interaction of these tools.

The mond and syslog daemons run on every node. The Supermon service manages requests for mond daemons that run on a subset of nodes. The mond daemon can be configured to pass any metric data for aggregation to the parent Supermon service. The Nagios master and other Nagios monitors run their check_metrics plug-in periodically, which causes Supermon data collection and storage into the database. The Root Supermon also connects to all other Supermon services and manages a subset of nodes. The syslog daemons report events to the syslog-ng services

Other tools, such as collectl, work independently from this structure.
