• Network Observability

Issue/Introduction

We are running on Netops 24.3.8. We have PM integrated with OI in our environment. Post the Linux OS patching we could not start netops-kafka service on the server and was timing out. Looking at journalctl -xe it showed startup was looking for a very specific version of java:

/app/CA/netops-kafka/kafka/bin/kafka-run-class.sh: line 353: /usr/lib/jvm/java-17-openjdk-17.0.15.0.6-2.el8.x86_64/bin/java

Environment

DX NetOps Performance Management

Cause

The OS patching upgraded the java verson on the system. The JAVA_HOME environment needed to be changed to the new version in the /etc/systemd/system/netops-kafka.service & /etc/systemd/system/netops-kafka-zookeeper.service

Resolution

The JAVA_HOME environment needed to be changed to the path to the new version of java in the /etc/systemd/system/netops-kafka.service & /etc/systemd/system/netops-kafka-zookeeper.service files and the services need to be restarted.
