Hello list, At the moment I'm using ipac-ng to provide the various departments within our company with traffic accounting figures. Our current approach has some nasty downsides which don't require elaboration at this point.
I'm looking around for alternatives for our current setup and pmacct looks very promising. What I need is fairly simple: We have 2 hosting locations with 2 class C public subnets each assigned to them (so roughly 1024 ip addresses in total). Per single IP we want to know the ammount of traffic to/from it in a given timeframe and a 95-percentile over a given timeframe. I know pmacct isn't suited for delivering these numbers directly but isn't the case with ipac-ng either. Having to do some scripting/programming to get the actual data is of no problem. On a more detailed side (and I admit I'm still reading the docs), I am wondering about some specific configuration issues. The memory size of various pools/buffers/etc in particular. One location has an 100Mbit/s uplink and the other 1Gbit/s uplink which is currently throttled to about 150-200Mbit/s. I don't have any actual numbers of packets/s, but only bytes/s and the fact that most traffic is HTTP. The average usage of both lines fluctuates between 20-40 Mbit/s with peaks upto 150Mbit/s for one location. Related to the above is also the performance of pmacct and the load it imposes on the machine. The firewalls in question are Dell PE860 machines with dual core Xeon's at 3GHz, 1 or 2GB of ram and running Suse Linux Enterprise Server 9. I hope some could shed some light on the things mentioned above. Thanks in advance.
