Dear all, I am currently investigating how pmacct can be used together with IPFIX data coming from Alcatel Lucent 7750 routers. During the past couple of days I hit a few questions I could not answer by myself: - From the documentation I reasoned that pmacct/nfacct is able to handle IPFIX sampling. I use IPFIX sampling with a sampling rate of 10000. From the results I see (pmacct or prng) the sampling rate is not recognised by pmacct/nfacct. I also tried to configure the sampling rate by using the configuration key nfacctd_ext_sampling_rate which did not resolve the issue. Is there a know issue with recognising the sampling rate from the IPFIX data? Or did I miss how to configure pmacct/nfacct correctly? - The aggregate configuration directive comes with various values. However, I could not find a way to aggregate IPv4 and IPv6 traffic. Did I miss this in the documentation? Or is it not supported by pmacct/nfacct? - I would like to generate rrd files for traffic going in and out of a MAC address. I also would like to generate rrd files for the communication between a MAC address and another MAC address (in and out). The configuration of pmacct/nfacct is actually quite easy. However, I had difficulties to generate the rrd files. I tried pnrg version 0.1 which is from 2006 and not updated ever since. It also has problems with creating rrd files and graphs based on MAC addresses. So I assume there should be a better solution than pnrg to generate rrd files. What is the default way of generating rrd files using pmacct/nfacct (I saw the section in the FAQ talking about rrd files, but this is nothing I can use as I would like to generate thousands rrd files :-))?
Any help/hint/feedback is highly appreciated. Thanks in advance! Best regards, Thomas
