Hi everybody again,
I'm using rsyslogd 4.6.4 in Debian 6 with UDP protocol.
The rate of loss, for example, in the last task audit, was: 200000 messages
sent, 11670 received.
I have checked graphical network statistics with a network specialist and
there aren't drop/reject with the packets. The outflow matches the inflow.
that high a loss makes me thing that you are still doing DNS lookups, and since
v4.x didn't have a DNS cache, each packat that arrives causes a lookup. Try
starting rsyslog with -x to disable the lookups, and I'll bet things get _much_
better.
the next thing is that with a version that old, sending it a HUP to roll your
logs causes a full restart. that's about when HUPisRestart was added, set that
to false
you really should move to a newer version if you can, multiple people have
succeded in getting ~400K messages/sec and it's much easier with the newer
versions.
