4/10 Q. ITOM Project Help !! (Please No Paste CHATGPT ANSWER)

SandeepKSingh · ‎08-26-2025

I must ensure Discovery and outbound integrations keep running even if one MID Server goes down. How we can Build a high-availability + failover setup for two (or more) MID Servers across the same network, so that:

Jobs are load-balanced during normal operation.
If MID-A fails, jobs auto-failover to MID-B (and vice-versa) with minimal disruption.
The design remains upgrade-safe and easy to support.

Hi @SandeepKSingh

Jobs are load-balanced during normal operation.

@SandeepKSingh

Setup a MID Server cluster and use it for discovery and integrations. This will act both as a load balancer and failover. Refer below link for more details,

@Ravi Gaurav

As per my understanding, it is not mandatory to setup heartbeat and MID Server cluster configuration is enough for failover to work.

You can refer Business Rule 'MID Server Cluster Management' for more information on the logic.

Monitoring heartbeat, failed jobs and job status in ServiceNow MID Server Dashboard is useful for tracking overall health of MID Servers.
