This contains the various message counters that syslog-ng maintains

'processed' counters just count how much messages were processed at the
given point, 'dropped' counters indicate how much log messages were
dropped by syslog-ng itself.

The string in the parenthesis tell were the given counter is counting
inside syslog-ng.

'center' is the main log message dispatching mechanism, it received
13206 messages from various sources and then sent 40295 messages out,
e.g. you are probably sending individual messages to multiple

You have two sources, one named 'src' generated 8962, the other called
'net_udp' 4244 messages.
