Playing devil's advocate... On Fri, Jan 20, 2012 at 04:34:42PM -0500, John Abreau wrote: > Something bad starts to happen, and it may be five minutes before > Nagios detects it. But, your network's behavior is likely constantly changing throughout the day, with various spikes and lulls in activity. Even if the "warning" comes more quickly, I'm imagining that the human minding the store will still take some time to decide that what's being emitted is something to pay attention to, rather than some random fluctuation that falls within the range of "normal" for that network. But I don't know how easy it is to filter out such things with Peep; I think this is one area where hearing about someone's experience with the system would be interesting. > A lot of damage can be done in five minutes. Maybe, but a lot of events are rather binary. If you, say, lose a critical volume on a server, it's gonna be down (or run in degraded mode) until you can restore it from some sort of back-up or rebuild it or whatever. Even if your company's website suffers catastrophic failure, most users will just see that your down and try again later. If your company's revenue depends on your website, surely you'll find a way to make sure this never, ever happens. A few minutes probably doesn't matter much in I'd guess the vast majority of cases. Certainly in 10 years of sysadmin experience, I can't remember too many occasions where I thought, "Jeez, if we'd only gotten to this 4 minutes sooner!" :) > And if you're using email alerts, you might not see the alert > immediately if you're away from your computer when it arrives. I guess you're piping the sounds from Peep through your company-wide PA system then? =8^) Which brings up my final point: Even if this does offer substantial benefits, you can only reap them while you're around to listen to it. Unless you're staffed 24x7, you're still going to need some other form of network monitoring and alerting for the times when the humans are all out having a beer. Does Peep still handle this? If not, are the benefits of this thing (if there are any) worth the time to set up and maintain an entirely separate monitoring system? I don't purport to know the answers, I really was hoping someone might have used it and could comment on their experience. -- Derek D.
