Issue/Introduction

http(s)://<DA>:8581(2)/rest/emregistration points to an incorrect address for Event Manager

Event Manager refuses connection from DA

System was migrated from production environment and the event manager registration was not updated on the Data Aggregator

System is being upgraded from older releases to new ones that require an SSL Certificate SAN name used.

Environment

All supported DX NetOps Performance Management releases

Resolution

1. Go to Administration->Data Sources->Data Sources in the Portal UI.
2. Choose to edit the Event Manager Data Source (DS)
3. Ensure the name listed is a SAN entry in the Portal SSL certificate. If it is not set the correct name that matches a SAN and save the changes.
4. Monitor the /rest/emregistration endpoint on the DA for the name to change.

If the name doesn't change after a short time follow these steps.

1. 1. Run the following from MySql on the Performance Center system. Default path shown, enter password when prompted.
      • /opt/CA/MySql/bin/mysql -uroot -p -e "update em.data_sources set LastEvent=0,ConsumerID=0;"
   2. Request an incremental sync of the Event Manager DS.
      1. Go to Administration->Data Sources->Data Sources in the Portal UI.
      2. Choose the Event Manager Data Source (DS)
      3. Choose the Resync button and then OK.
      4. DO NOT select the full sync check box.

Monitor the ../rest/emregistration endpoint on the DA for the name to change. If it still doesn't change after 20-30 minutes at the most, open a new case with the Support team for additional assistance.
