We Love Rsyslog

Every day we’re growing to appreciate rsyslog more as we scale up. Yesterday I captured this shot of iptraf running on one of our event routing hosts. 158mbit/s in and 583mbit/s out for a combined total of 740mbit/s of traffic being handled by a single rsyslog server. The server is both filtering and routing by various message properties. At this rate of traffic the hardware isn’t even breaking a sweat. We realize we’re a bit off the beaten path with our use of rsyslog for message routing at AK. This screen capture is part of the story as to why:
