I read the thread about java agent attach dated July. The last comment there was that someone(I guess from Elastic) is making an update on the java-agent-attach that will allow detaching. Is that possible now? If so, how is it done?

There is a work-in-progress, currently in the POC stage, of making a major change in the agent that will eventually allow "hot-update" and detach as well, but not something in the immediate future.  
Once it is done, we will document what it means.

We already have [the `active` switch](https://www.elastic.co/guide/en/apm/agent/java/current/config-core.html#config-active), maybe it can serve what you are looking for until then.

I hope this helps,  
Eyal.

Great! Does the attach agent query ELASTIC\_APM\_ACTIVE variable like every minute?
