I can't help on the mail front, as I sold out to Gmail years ago now. However, iftop and iotop sound like tools that may help with your load troubleshooting. Think of them like being the equivalent of top, but for block and network device I/O instead of CPU and memory utilization. -N ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
Two things: anti-spam and per-process *network* I/O.
Hi, all. I've had two things that occasionally cause me grief, and since I finally got around to sending an e-mail, I figgered I'd roll 'em into one. So: I used to use MailScanner as my anti-spam solution, but it seems to be wandering into unsupported territory in Ubuntu land, and, for fear that this might be a trend, I wonder what other solutions other folks out there might be using. (Note: Gmail! isn't really the kind of answer I'm looking for.) Per-process I/O accounting. Every now and then, I see a system load spike through the roof -- but disk I/O is okay, likewise CPU. Which really pretty much leaves network. But I'm unaware of any tool that spits out per-process network utilization statistics. One *must* exist, right? Any pointers? Thanks much, and happy holidays to one and all! -Ken -- This mail was scanned by BitDefender For more information please visit http://www.bitdefender.com/links/en/frams.html ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

But I'm unaware of any tool that spits out per-process network utilization statistics. One *must* exist, right? Any pointers? So, to confirm, when these incidents occur, the load average on the machine is low? I'd suggest using ntop and if things aren't clear from just this, using some combination of lsof -i ... or netstat -p.
