How to: Uninstall the New Relic agent for a Web App
The New Relic agent is a powerful lightweight agent that helps you monitor the performance of your Web Application. Thanks to it you can identify potential problems, measure performance, and deliver a better user experience. So why would you want to uninstall it? Well, in my case I was playing with a bunch of plugins that created a bunch of “apps” out of my main web app. Long term this is desirable as I can measure the performance of my overall deployment but also subsite by subsite I can see how the server is behaving. The only issues is that as I was playing with this functionality I switch the naming of the applications and different plugins created different apps. In one case each subsite had 3 sites: the regular one, the admin one, and I believe an ajax one… too much for me. So at the end of the day like 10 sites, 5 flavors of each…. a nightmare. Now, New Relic won’t let you delete an application that is active and it won’t merge sites… so the only option is to uninstall the New Relic plugin for like an hour so that their site lets you delete your apps.
Uninstalling the agent
Note: Make sure your applications are not reporting any data (their “traffic light” status is gray) before uninstalling the agent.

To remove the Java agent:

Can we use Let's Encrypt, the free and open certificate authority?
Hola! gracias por la info, me sirvió el comando sacandole el nombre del server. En mi caso, fue una migración…
Yes 3rd option helped me too. I removed the WC key Values from config file then started working.
I know this is from 2014. But really, thank you!
