How to interpret load average

Latest response

Hi,

Please help me with below query:
How do we determine that the processor is fully loaded? What numbers can be used?
For example: In a 32 cores system, the load average value when the processor is 100% loaded is 32 ?

Both sar and mpstat can be used to show per-processor loading metrics.

Hi Tom,
Thanks for your reply.
Do you suggest to use sar or mpstat instead of load average to see if the processor is fully loaded?
Any comment on load average values?

mpstat for real-time metrics
sar for historical data (typically configured to snapshot at 5-15 minute intervals)
