Are there any tools to monitor state of a Flume channel and, specifically, determine the moment when there are no more events?
To give you some context: I have a batch of events that I want to pass through Flume and eventually get to HDFS via corresponding sink. When all events of the batch are dumped, I want to perform post-processing routine on the entire batch. My assumption is that if channel is empty for a while, all events of the batch are dumped and I can start the routing. But how can I determine if channel is empty?
