<div>Hi<br>
<br>
</div>
I call recon:scheduler_usage(5000) when cpu usage is low (100% ~
200% from top, with 32 cores)<br>
<div>It show all scheduler usage is 1.0<br>
</div>
<div>Is this possible? all schedulers are busy but cpu usage is
low<br>
</div>
</div>

<br>
Yes, it is possible.<br>
<br>
Schedulers waiting for os resources are considered utilized (they
cannot handle more work).<br>
<br>
This is why scheduler utilization exists. CPU utilization is often
used as a load measuring device but it is a very poor estimate load.<br>
Scheduler utilization is a better estimate.<br>
