Hi @Helmet,

it seems that the simple monitor is not able to connect to Hazelcast. By default, the Hazelcast instance is created by the Hazelcast exporter that runs in the Zeebe broker.

  • Make sure that the exporter is configured properly.
  • Check the Zeebe broker logs if Hazelcast is started successfully.
  • If the Zeebe broker takes too long to start then increase the time out in the simple monitor

Does this help you?

Best regards,
Philipp
