Issue/Introduction

Title: Alarm for Distributed Load Balancer Service Status Down

Event ID: load_balancer.dlb_status_down

Alarm Description:

• Purpose: To inform users that the distributed load balancer service is down.
• Impact: All the traffic to this distributed load balancer is broken.

Environment

VMware NSX-T Datacenter
VMware NSX

Cause

There is no ready LSP for the distributed load balancer on all ESXi hosts.

Resolution

Steps to resolve
For 3.1.2 and higher

Recommendation Action:

1. On ESXi host node, invoke the NSX CLI command `get load-balancer <lb-uuid> status`.
2. If 'Conflict LSP' is reported, check whether this LSP is attached to other load balancer service. Check whether this conflict is acceptable.
3. If 'Not Ready LSP' is reported, check the status of this LSP by invoking NSX CLI command `get logical-switch-port status`.

Note: Enable DFW for DLB workloads. Disabling DFW either globally or through the DFW Exclusion List will cause an outage on DLB workloads. Reference Documentation: Distributed Load Balancer
