Attaching Java agent after VM has started

jdudleyk 2016-12-21 18:51:43 UTC #1

We want to be able to monitor applications that we deploy to Mulesoft's CloudHub platform. The Java applications are running in tomcat containers, but we have no control over the java properties that are set so we are unable to start the NewRelic agent as we cannot set the -javaagent property.
From the Java docs it is possible to attach a Java agent to a running JVM, but this is failing as the Agent-Class property is not set in the manifest file of the newrelic.jar file.
Do you perhaps have any suggestions for how we could get the New Relic monitoring going on a Java server for which we do not have control over the server startup properties?

Feature Idea: Allow the agent to be added as the VM is already running

@jdudleyk, I believe you found an answer to this question via a support ticket opened with us.

For other people reading this forum post, it is not possible to attach our Java agent a running JVM. The concept of 'Java agents' is broad and with some Java agents this is possible. With the New Relic Java Agent, the particulars of the agent's design require that it be included when the JVM is started. It cannot be attached to a running JVM, after it has already been started.

Without a way to configure JVM command-line options in some way (which does not appear possible with CloudHub at this time), our Java agent cannot be used.

Again, to anyone reading this, please let us know with replies here if you would like to see us support Mulesoft's CloudHub platform and we will enter a unique feature request on the behalf of each person that does so.

I would love to see the support of CloudHub platform, especially on the support of the HTTP Connector.
