VNA server ran out of disk space, this was resolved but we see no VNA data in Spectrum or DX Netops Performance Management
We see the following repeated in the server.log on VNA:
YYYY-MM-DD HH:M:SS,### WARN [org.apache.activemq.artemis.core.client] (Camel (broker-plugin-context) thread #33 - JmsConsumer[InventoryUpdateQueue]) AMQ212058: Unable to get a message.: java.lang.IndexOutOfBoundsException: Error reading in simpleString, length=####### is greater than readableBytes=#####@ClientLargeMessageImpl[messageID=######, durable=true,
Where the messageID=###### is the same id over and over again.
Release : 20.2
Component : Virtual Network Assurance For CA Performance Management
This indicates a corrupted activemq message.
To clear the activemq cache (adjust paths for your installation directory):
systemctl stop wildfly
cd /opt/CA/VNA/wildfly/standalone/data/activemq/
tar zcvf /tmp/journal.tar.gz journal
cd /opt/CA/VNA/wildfly/standalone/data/activemq/journal/
rm *.amq
cd /opt/CA/VNA/wildfly/standalone/data/activemq/largemessages
rm *
systemctl start wildfly
This clears the activemq messages, eliminating the error.
