C.5. Linux
The probes in this section monitor essential aspects of your Linux systems, from CPU usage to virtual memory. Apply them to mission-critical systems to obtain warnings prior to failure.
Unlike other probe groups, which may or may not require the Red Hat Network Monitoring Daemon, every Linux probe requires that the
rhnmd
daemon be running on the monitored system.
C.5.1. Linux::CPU Usage
The Linux::CPU Usage probe monitors the CPU utilization on a system and collects the following metric:
- CPU Percent Used — The five-second average of the percent of CPU usage at probe execution.
Requirements — The Red Hat Network Monitoring Daemon (
rhnmd
) must be running on the monitored system to run this probe.
