Persistent Queue Question and Upstream Block Signals
I have a question about persistent queues. I thought their behavior was such that if you have a persistent queue, blocking signals would only be sent upstream to sources if that PQ is full. I seem to be seeing behavior that does not match that. I am seeing blocked TCP JSON destination that keeps flapping due to
output is experiencing increased load errors. It has a PQ and the PQ is empty. This is causing syslog source and elasticsearch sources to drop.
What should we expect to see when a destination is blocking and it has a configured PQ. Should sources be blocking?
