NAME

na.cpustat - per cpu statistics (Solaris 2.x)

DESCRIPTION

na.cpustat returns statistics of all the cpus on the system

A reporting interval is specified by the management application. If a reporting interval is not specified, the agent will send a report every 30 seconds.

ATTRIBUTES

na.cpustat has three attribute tables, load_stats, system_stats and vm_stats .

The load_stats table reports load statistics about a particular cpu , using cpuno as the key.

cpuno Cpu Id as represented in kernel (int)

user

time spent in user mode since system boot (unsigned long)

sys

time spent in kernel mode since system boot (unsigned long)

idle

time spent in the in idle (unsigned long)

madpE Adaptive mutex enters for this cpu(unsigned long)

no of traps (unsigned long)

intr

no of interrupts (unsigned long)

migr

no of thread migrated to another cpu (unsigned long)

The system_stats table reports system statistics about a particular cpu , using cpuno as the key.
