Now, checking the udp drop counters on the old server, indeed I see some 25000+ drops. That counter seem to increase during the refresh time of the sql plugin. Not always though. Is there a connection between the drops and the mysql insert/update process? If so, would running the mysql server on a different server eliminate any future possibility of that happening again?
Get those fixed (if they increase while nfacct is running and if you can't ensure, that the drops are caused by any other UDP packets hitting the box). Increase max UDP receive buffers on the box and set nfacctd_pipe_size. Make sure nfacct is really using the new buffer size ... you may consider offloading mysql to a different server, but if usually increasing buffers to be prepared for peaky incoming flow data should be sufficient (sure, depending on how much data you receive). For dropped flow data you'll never get stats. Cheers, Markus _______________________________________________ pmacct-discussion mailing list http://www.pmacct.net/#mailinglists
