[slurm-users] Set a ramdom offset when starting node health check in SLURM

[Micheal Krombopulous]

Call healthcheck with a shell script that starts with:
sleep $[ ( $RANDOM % 10 )  + 1 ], or similar.

Subject: [slurm-users] Set a ramdom offset when starting node health check in SLURM

Hi,

   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.

   Is it possible  to set a random offset to when HealthCheckProgram starts?


Thank you!
