How to know if any @Scheduled operation is running

[cocorossello <co...@gmail.com>]

Hi, 

I'm trying to implement an "autostop" bash (or equivalent) script for tomcat
(I want to implement an "autoscaled" cluster, although I'm a newbie on
this). 

The script would check for active sessions and stop the server (and the VM)
whenever is 0, but we also need to look for active @Scheduled operations and
I was wondering if there is an easy way to look for this. The other option
is to implement a custom interceptor, but I was wondering if there is
already a solution for this.

Thanks in advance

Hi

just throwing out an idea: did you check if it was available in quartz JMX
MBeans?

Issue is you will likely get the scheduled tasks but maybe not the "in
progress" information. An interceptor sounds good and you can expose it the
way you want (like having a file you can check in your script which is
easier than having an endpoint if you run in a secured environment where
curl/wget/... are not present).
