We have a production environment (cluster) where there are two physical servers and 3 (three) plone/zope instances running inside each one.
We scheduled a job (with apscheduler) that needs to run only in a unique instance, but is executing by all 6 (six) instances.
To solve this, I think I need to verify if the job is running in the server1 and if it is a instance that listens on a specific port.
So, how to get programmaticly informations about a zope/plone instance?
