Troubleshooting

Follow below steps if in any case the Hazelcast Custom UI does not show cluster(memory utilization) or member information.

  • Check if Hazelcast cluster is up and running. If yes then simply restart Tomcat service.
  • If Hazelcast cluster is down then first start hazelcast cluster followed by restart of Tomcat service.
  • If npm install gives certificate issue then execute command npm config set strict-ssl false from $GIT_CLONE_DIR/UI_Code directory.
  • If unable to find Node during the command npm install. The issue is due to the name difference. As in system it is nodejs while code is looking for node. To resolve the issue run command sudo ln -s /usr/bin/nodejs /usr/bin/node. It will lync nodejs with node.
  • If one faces permission issue due to the lock on folder in UI code. The execute command sudo chmod 777 <path> -R to resolve the issue.
