How to disable a JVM agent
I bought 21 JVM licenses to share across 30 non prod servers. My question involves disabling agents on 1 server so I can enable it on another. Is there a way in the DT Client to disable an agent or do I need to remove the application command line in the bootstrap and bounce the JVM.
Second question, I'm looking at the License Information under the DT Server Settings and it show the total number of agents I own, but I do not see a place to tell how many I have available. Do I have to go to the Agents Overview page and count up the agents listed?
Another trick we use to manage licenses is to disable a profile you don't need at the moment and restart the collector those agents connect to. This will free up those licenses and not require a restart of the JVM.
Melory,
Running 6.1 on the Server and Collector but my agents are still 6.0. Plan to upgrade them in the next week or so. Bouncing the JVM is better then having to pull the command line, but sure would be nice to manage this from the DT Client.
Hi Bob,
For your first question: As far as I know there's no a official way to do that, but there are some ways you can release licenses without remove the command line.
- Which version of Dynatrace are you using? Because for DT 6.0+ you have the option to play with Reservation tab:
- I generally use the strategy to unmap agents from agents group. For example, I have 5 agents mapped to BOL agent group, so I use the "start with" BOL. In order to release license I change the alias from my agent group "Disabled_BOL". The drawback is you need to restart you JVMs.
That will work if you have more then one agent group.
For your second question: You can use the License Count Plugin to get that information. That worked fine for me. -> License Count

Melory
