vRNI services stopvRNI stops collecting data and cannot access GUIvRNI services do not startWhen you run the (cli) show-service-status command, you see similar output when vRNI is not in sync with NTP: ElasticSearch is running HMaster is running HRegionServer is running Kafka is running QuorumPeerMain is running ResourceManager is running NodeManager is running Problem: SaasListener javaservice is not running. Problem: Restapilayer javaservice is not running. Problem: ClusterBasedJobCoordinator javaservice is not running. Problem: SamzaContainer javaservice is not running. Problem: Launcher javaservice is not running. Postgresql is running Problem: Nginx service is not running. Patroni is running ExpressJSApp is running NTP is running but not healthy.
From vRNI version 3.5, the deployment setup must be IN SYNC with the configured NTP. If some of the components cannot reach NTP or go OUT Of SYNC, the services stop and cannot be started.
Sample TCPDUMP output of working vs non-working setup: Ensure that connectivity to NTP Server is working. NTP server is connected on UDP Port 123. Verify the NTP configuration by running this command: (cli) show-config You see output similar to: network configurations: IP Address: 192.168.1.100 Netmask: 255.255.255.0 Gateway: 192.168.1.1 DNS nameservers: 192.168.1.1 192.168.1.2 Domain Search list: example.com NTP servers: time.google.com If any change is required in NTP configuration, perform these steps: Log in to Platform / Proxy as consoleuser.Run this command:. (cli) setup You see output similar to: Running setup: Interactive Mode.
