Sar CPU usage for each processor

Question

In Linux, mpstat allows you to specify a specific processor or all processors when getting CPU % usage. In OS X, sar looks pretty limited as I can only get CPU usage for all processors. I'm trying determine how many cores are in use (basically for figuring out how many single cores are available for jobs if im submitting 1 handbrake job per core)

Answer 1

hello,
I sugget to create a time series chart with the following SQL:
with p as (select target_guid,property_value cpucount from mgmt$target_properties where property_name='CPUCount' and property_type='INSTANCE')
select h.target_name,
h.rollup_timestamp,
h.average/p.cpucount pct_cpu
from mgmt$metric_hourly h,p
where h.metric_name='instance_efficiency'
and h.metric_column='cpuusage_ps' and h.target_guid in (select target_guid from mgmt$db_dbninstanceinfo where target_type='oracle_database' and host=??EMIP_BIND_TARGET_GUID?? )
and h.rollup_timestamp between ??EMIP_BIND_START_DATE?? and ??EMIP_BIND_END_DATE??
and p.target_guid=h.target_guid
order by 1,2
You have to select the host target in the report and period is customizable.
I hope this is correct and answers your question.

Noel
