Hi there,
Not sure if it helps, but what we did is add a JVM-specific argument in
resin.conf: jvm-arg-Dresin.node=NodeName/jvm-arg and then use that
in our shell scripts to help determine the specific PID for each resin
node (through some ps + grep magic). So far we have stayed with 3.0 due
to some differences with the new watchdog process, but that's how we did
it when we tested 3.1 and it seemed to work fine.

Hi
After using Resin 2.1 for a long long time we upgraded to Resin 3.0
some time last year, and some months ago to 3.1.
We use stacktraces from the running VM for debugging, but the process
of retriving the correct PID when running on unix is now quite hard
when we have 10+ resin VM’s running on the same server (jps just shows
multiple Resin and WatchdogManager processes).
Previous versions (prior to 3.1 at least) used to have a –pid-file (or
similar) option, so the parent resin PID was recorded. This made it
easy to get hold of the child PID with a bit of gawk-magic, but with
3.1 this is no longer a possibility.
What can I do to record the PID of a newly launched Resin process – or
even better – the PID for the Java VM it spawns?
I've added a bug report for this at http://bugs.caucho.com/view.php?id=2855
We can add the pid to the watchdog status command or even create a
watchdog pid command to get the pid for a -server. I don't think it's
possible currently, unless you use JMX to ask each Resin instance what
its -server and pid are.
