All Host details are not visible in kibana APM UI

All Host details are not visible in kibana APM UI even though CPU usage was detected for a certain time period . i had installed java APM agent into my host for easytravel application as demo run.

Please find SS attached for your referrence.

the java agent on it's own only provides JVM available metrics not all host metrics. You can see the JVM metrics by going to the APM->services, choosing your Java service and selecting the metrics tab (jvm tab in earlier versions).
