Hi Julien,

we use the

LPTSTR WINAPI GetCommandLine(void);

function to get the command line. Apparently the jvm runs inside a thread in the same process that this .exe has started, so we get this line and not the jvm call. So unfortunately, in this case you won't get the jvm parameters from our agent. Maybe there's some way from the Weblogic management console. Best regards,



Thanks a lot for your quick answer. Do you know if there is chance to have this capability in next Dynatrace release ?

I don't know for sure, but I'm relatively certain that it's not on the road map.

To get the jvm parameters from inside the process we'd have to use a jmx bean, as far as I've understood, and this might'nt be reliable enough to implement as code that gets injected into customer applications.

Also, this special case (a jvm thread running inside a native process) isn't very wide-spread, I think.
