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

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! Jianwen
