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.
Release : 21.2
Component : NetOps Portal web server
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
systemctl stop activemq
systemctl stop dcmd
systemctl start dcmd
Note starting dcmd will start the activemq process.
