Products

• VMware Aria Suite

Issue/Introduction

Symptoms:

• Attempts to generate a heap dump from the Orchestrator control center, results in an "Error! 500" message.
• The body of the message contains a 'no such file or directory' error similar to the screenshot below:

../app-server/logs/tomcat.pid (No such file or directory)

 

Environment

VMware vRealize Orchestrator 8.x

Aria Automation Orchestrator 8.x

Cause

Due to architecture changes in the 8.x release the Orchestrator heap dumps can no longer be collected from the Control Center interface.
In 8.18.1, the controlcenter is deprecated and heap-dumps must be collected manually.

Resolution

The issue is pending a resolution.

Workaround:

The heap dump can be manually collected with the following steps:

1. SSH into the one of the Orchestrator appliance nodes as the root user.
2.  Execute the following command to generate the heap dump:

VCO_APP_PODS=$(kubectl get pod -n prelude -l app=vco-app -o jsonpath="{.items[*].metadata.name}"); for VCO_APP in $VCO_APP_PODS; do kubectl -n prelude exec -it $VCO_APP --container vco-server-app -- bash -c "jcmd 1 GC.heap_dump /usr/lib/vco/app-server/logs/heapdump-$( date '+%Y-%m-%d_%H:%M' ).hprof"; done

The heap dump will be generated in the below path: 

/data/vco/usr/lib/vco/app-server/logs

 

Additional Information

Impact/Risks:

Users are unable to generate the heap dump from control center.
