Workbench is an inbuilt feature provided with each extension in order to assist you to fine tune the extension setup before you actually deploy it on the controller. Currently, the AppDynamics Platform does not allow a user to delete a metric once it has been registered. As soon as you deploy an extension directly after downloading, it will have several default settings and you’d like to make a minor change, say in the metricPrefix of the extension after you deployed it with the default configuration, the platform would not allow you to delete the metrics with the default metricPrefix and you will have to keep the old metrics as well.
This is a very useful feature that comes in handy and should be used during the process of deploying each extension as it would give you a better idea of what metrics are going to be recorded, and in case you see that you are missing some metrics, this tool will give you an opportunity to add those metrics as well. Workbench functionality is inbuilt with each extension JAR file. In order to use this feature, please follow these steps.
