vIDM cluster experiencing problem with OpenSearch and RabbitMQ services.

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• The vIDM health check is returning a red status
• The error 'There was a problem with Opensearch service' is received on one or more nodes.
• The error 'There was a problem with Messanging Service'. is received on one or more nodes.
• The Integrated components section of the vIDM admin UI may not load.

Environment

VMware Identity Manager 3.3.7

Cause

This can be caused when the '/db' partition of the cluster nodes becomes full. This can be confirmed by running the command below;

df -h

Resolution

There are three steps to resolving this issue.

1. Follow the steps outlined in the KB below to clear large tables from the database;
   • vIDM 3.3.x vPostgres DB OAuth2RefreshToken table consumes most space on the appliance leading to service outages
2. Run a stop/start cycle on Opensearch services

   • /etc/init.d/opensearch stop
     /etc/init.d/opensearch start

3. Run a stop start cycle of RabbitMQ services

   • /etc/init.d/hoizon-workspace stop
     rabbitmqctl stop_app
     rabbitmqctl start_app
     /etc/init.d/hoizon-workspace start

Additional Information

To access the vIDM admin UI, add the extension '/SAAS/admin/systemDiagnostic' to the end of a node; FQDN.
