Re: [rsyslog] Understanding parallelism and queues

[siddhartha dewan via rsyslog]

Got it and thank you. 1 strange thing - when i use a queue in a ruleset -
impstats shows name for the queue - but it never ever shows any message
count increment.
It always shows increments only in mainQ and "imtcp(514)";  for example - i
have named the queue of my ruleset "tcp_mainq" - i see the DA queue and the
linkedlist queue - but its values never change - is that expected? I would
expect the worker threads to pick up all the messages;
Here is an example:
