Currently all message intercepted by the wire tap are published to the window for events of type org.opencredo.esper.integration.MessageContext and all throughput monitors use a count query on this window. The result of this is that where we have multiple monitors each one reports the global total throughput for all channels being monitored rather than the throughput for the channel the monitor is configured with. We need either to query the global message context window by channel id or create a window which only contains events relating to one channel.
