System Monitoring

System monitoring refers to inspecting runtime system metrics such as CPU usage, temperature, or uptime, in real-time.

The last section of the show version command displays a snapshot of most useful metrics:

Additionally, OSDx supports displaying some of these metrics in a text-based dynamic graph through the monitor system graph command family.

Examples:

../../../_images/cpu_graph.png — *CPU graph*

../../../_images/mem_graph.png — *Memory graph*

The graph may be exited by pressing Ctrl+C.
