We ping our flume metrics every 5 minutes and push the results to a TSDB (http://opentsdb.net/) database. TSDB is great for visualizing your data rates. Depending on your flume configuration, you will get greatly varying rates. If you are using spinning disks with a file channel you'll want to make sure your checkpoint directory and and data directory are on physically different disks.

In the case when the sink slows down and event taken from the channel falls behind while the event puts continue at the same pace, how would one go about finding the amount of backlog or time it takes to clear the backlog?
