<div dir="ltr">Hi,
<div>I am facing issue in getting pcs alerts for fencing
resources.</div>
<div><br>
</div>
<div><b>Scenario:</b></div>
<div>1. Configure the pcs alerts</div>
<div>2. Add stonith resources (resources are unreachable)</div>
<div>3. No monitoring alerts received.</div>
<div><br>
</div>
<div><b>Note:</b></div>
<div>If stonith resources (reachable) are successfully

up.</div>

Do you have any evidence that monitoring is happening when
"resources are unreachable"<br>
( == fence_virtd is reachable?) like logs?<br>
I would guess that there is no monitoring unless the
fencing-resource is accounted<br>
as started successfully.<br>
<br>
