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)

wio time spent in the in idle waiting for IO(unsigned long)

idle time spent in the in idle (unsigned long)

madpE
Adaptive mutex enters for this cpu(unsigned long)

traps
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.

The vm_stats table reports per CPU virtual memory statistics , using cpuno as the key.

ERRORS

Fatal Internal Error
An error internal to cpustat occured; contact the support

System Internal Error
An error occured due to system misbehavior ; contact the support

Data build failed
Error occured while building a response ; contact the support.

Too small a frequency; Agent overloaded
