---------------------------------------

             Summary: Create new metric for the number of subscribers of distribution publisher
                 Key: SLING-8934
                 URL: https://issues.apache.org/jira/browse/SLING-8934
             Project: Sling
          Issue Type: Improvement
          Components: Content Distribution
            Reporter: Alexei Krainiouk


In some cases the replication_journal_availability metric reports that journal is available
but replication does not work.

In these cases a typical indication was that the publisher does not see any queues or not
all queues.

So I would like to introduce a metric of the number of queues the author sees. We can then
create an alert based on it that triggers if the number of queues stays below 2 for a certain
time. (1 golden master, 1 publish).
