<div class="PlainText">Hi,<br>
<br>
We uses HealthCheckProgram = /usr/sbin/nhc in slurm to check node health every 600 seconds. However, some NHC checks points to a same central resource thus starting these checks simultaneously may lead to false alarms of service degrade.<br>
<br>
Is it possible to set a random offset to when HealthCheckProgram starts? <br>
<br>
<br>
Thank you!<br>
