If you want execute a query from Prometheus for some attribute of a Universal Messaging channel (JMS topic) or queue, you supply a query of the following form in the query field:

where <AttributeName> is the channel or queue bean attribute name and <ChannelName> is the name of the channel or queue.

For example, if you already created a channel "C1" and want to get the NumberOfEvents attribute, enter "NumberOfEvents_C1" in the query window.
