Title: Alarm for high_availability.tier0_service_group_failover

Event ID: high_availability.tier0_service_group_failover

 

Alarm Description:

• Purpose: To inform users a tier0 service group has state changed on edge. It may not mean service group itself has issue. Please check events from syslog around the time of failover.
• Impact: Failover could be triggered by various factors, including peer state. If state change is expected, traffic should be picked up by the active service group.

Environment

VMware NSX-T Datacenter
VMware NSX

Cause

Caused by T0-SR routing down or uplink device down. Please check events from syslog

Resolution

Steps to resolve
For 4.0.1 and above

Recommendation Action:

• As admin user, on the edge node, invoke the NSX CLI command `get logical-router <service_router_id> service_group` to check all service-groups configured under a given service-router.
• Review the result to identify a reason for a service-group leaving active state.
