Data Collectors not showing in Netops post 21.2.12 Upgrade

Products

• DX NetOps

Issue/Introduction

After upgrading to 21.2.12 and installing new Data Collectors they are not showing up in the Netops portal.  All queues are showing as successfully connected to the DA, no errors in any of the logs, Mq, karaf, or system logs.  I have recreated both /data directories and restarted activemq and dcmd services after killing and lingering java processes.

Environment

Release : 21.2

Component : NetOps Portal web server

Resolution

Perform the following steps to get the data collector running. 

mv /opt/IMDataCollector/apache-karaf-4.2.6/data /opt/IMDataCollector/apache-karaf-4.2.6/data.old 
rm /opt/IMDataCollector/apache-karaf-4.2.6/deploy/local-jms-broker.xml

systemctl stop activemq
systemctl stop dcmd 
systemctl start dcmd 

Note starting dcmd will start the activemq process.
