The Uptime Infrastructure Monitor agent uses the sar -u -f command to collect CPU metrics from a Solaris system. The statistics returned by the agent are averaged for all CPUs on the system and the sar command compares the system counters during a one-second interval. In multi-CPU systems, the CPU statistics output by the agent are an average of all the CPUs on the server.
