Description
This template monitors metrics related to Global request processor, threadpool, servlet, JSP and few performance related metrics.
Prerequisites
Java must be installed on the device. Gateway should be up and running. The device should be reachable from Gateway. The device should be in managed state.
How to Apply: For TomEE Plus we have Instance Based Monitoring or Component Discovery Monitoring. In order to do that, we should add the following custom parameter.
application.component.name : GlobalRequestProcessor
application.component.name : ThreadPool
application.component.name : Servlet
application.component.name : Jsp
Create different monitors for different components in Instance based monitoring.
Only one component is allowed per monitor in Instance based monitoring.
We have three different types of Component Discovery Monitoring. They are :
For a single component :
ALL : ALL your instances will be monitored.
Expression : The Instance Names that match the expression will be monitored.
Metric Parameters
