In my (admittedly very limited) experience, you think you just want something simple and lightweight and then quickly discover you actually need more and more features. Nagios was designed for exactly this sort of thing. While it isn't a 15 minute solution, the ~half a day you'd spend getting a basic Nagios setup in place is probably worth it.

The issue with the single system is that the NIC seems to die, but none of the logs indicate the failure except that if cannot connect with the NFS server. I've activated the second NIC on the MB, but I'm pretty sure that it will die too. In any case, I've just been putting off the nagios installation, but it is time to bite the bullet. -- Jerry Feldman g...@blu.org Boston Linux and Unix PGP key id: 537C5846 PGP Key fingerprint: 3D1B 8377 A3C0 A5F2 ECBB CA3B 4607 4319 537C 5846 ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
Re: Lightweight network monitoring program
That was certainly an approach. I actually wrote a script that does a ping test. This was done for a different purpose such as uploading stuff to systems when I make changes to things like automount. The only reason not to do this is that it just adds one more homegrown script to the mix. But also I don't monitor my work email all that much since a lot of times I'm on my Linux workstation, although if I send it to my gmail account, my smartphone will beep at me. result=$(ping -c $COUNT $HOST) if [ $? -ne 0 ]; then ## log something or send mail fi On 02/28/2011 10:34 AM, Chris O'Connell wrote: Jerry, Here are some step-by-step instructions on installing nagios: http://outlookoutbox.blogspot.com/2010/11/nagios-installation-step-by-step_15.html On another note, it sounds like you just want a ping check to see if these hosts are up? Couldn't you dump ping results to a file, have the file searched for UNREACHABLES and then use sendmail to email you if one of the hosts doesn't show up? Seems like maybe 20 lines of code or less (far less I would think) would take care of this. -- Jerry Feldman g...@blu.org Boston Linux and Unix PGP key id: 537C5846 PGP Key fingerprint: 3D1B 8377 A3C0 A5F2 ECBB CA3B 4607 4319 537C 5846 ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
