In this chapter we covered monitoring Flume agents both from the process level and the monitoring of internal metrics (is it doing work?).
Monit and Nagios were introduced as open source options for process watching.
Next we covered the Flume agent internal monitoring metrics with Ganglia and JSON over HTTP implementations that ship with Apache Flume.
Finally, we covered how to integrate a custom monitoring implementation in case you need to directly integrate directly to some other tool not supported by Flume by default.
In our last chapter we will discuss some general considerations for your Flume deployment.
