Answer 1

Response from evernote, there is a bug in current collector javamelody server, server not supported blank space in server name while adding on aggregate server.

hope could help !

Answer 2

I personally had a similar issue where I wanted to get ride of a collected monitoring. I end up editing the applications.properties file on the collect server.

vi /opt/tomcat/temp/javamelody/applications.properties

You will be able to see the list of monitored application

#urls of the applications to monitor
#Wed Nov 07 12:08:01 GMT 2018
YouApplication\ serverA=http\://serverB\:8080/YouApplication

Then after removing the YouApplication line and restarting the servers it was all good.

Hope it will help.
