Metric reporters with non-static ports

[Jared Stehler <ja...@intellifylearning.com>]

The prometheus metric reporter allows for a specification of a port range; is there a way I can find out which actual port it found to bind to?

Also, there doesn’t seem to be a way to reserve an extra port for task managers in mesos to assign to a metric reporter, is that a roadmap item? I’m able to override the port for the app master (-Dmetrics.reporter.prom_reporter.port=$PORT1) but this carries over to the task managers and can collide with the assigned data port, etc.

Yes the logs are the only way to find out which port the reporter is 
bound to.

We may be able to display this information in the web-UI, but it isn't 
very high on my list and will probably require
modifications to the reporter interface.

That way you can just assume that each port was taken and used.

I am not sure (and because of holiday season you might not get an answer quickly), however I do not see a way to obtain this port other then by looking into the log files. On the other hand, I have an impression, that intention of this feature was that if you must execute N reporters on one single machine, you configure port range to the size of N. That way you can just assume that each port was taken and used.

Maybe Chesnay will be able to answer this question better once he is back from the holidays.
