Event collector
The collector buffers data locally for up to collector.max-buffer-time,
which defaults to one minute. The collector uploads
this locally buffered, non uploaded data after a restart.
Any upload failed due to errors in accessing the file, snappy errors
or Json format errors will result in the file being moved
to the 'failed' subdirectory of the local staging location.

Event Tap Stats Resource

failure. Flows are identified by event type, flow ID and target URI.
