What's the meaning of “cpu_intr” and “cpu_sintr” in ganglia

Question

Where can I see these metrics of explanation？

cpu_ctxt, cpu_intr, cpu_sintr, cpu_aidle, cpu_steal

Answer 1

I would assume that cpu_ctxt represents the number of context switches as reported by /proc/stat (see manpage ) or vmstat ( cs field).

Also, man top reveals the meaning of the other metrics:

       us, user    : time running un-niced user processes
       sy, system  : time running kernel processes
       ni, nice    : time running niced user processes
       id, idle    : time spent in the kernel idle handler
       wa, IO-wait : time waiting for I/O completion
       hi : time spent servicing hardware interrupts
       si : time spent servicing software interrupts
       st : time stolen from this vm by the hypervisor

where:

• cpu_intr maps to hi
• cpu_sintr maps to si
• cpu_aidle maps to id
• cpu_steal maps to st
