Before I invest time and energy looking for alternatives, I'm hoping someone can help me out here.
I installed Nagios 3 about a year ago and spent a lot of time trying to get it set up properly, but I'm starting to get really frustrated.
When there's an outage on some part of my network, I either get a FLOOD of alerts or none at all. For example, I do NOT want to get alerts because every device is down, I only want to receive an alert on the top-most parent item.
Today, I had a leg of my network go down, but received NOTHING from nagios on it. I have one device (a Dragonwave Horizon bridge) that can't be monitored from this side of the network, but it and everything behind it went down, and I got absolutely no alerts until the network came back up, at which point, I got a few scattered UP alerts.
This is making no sense to me, and I'm not sure where I need to start looking for an answer.
Thanks in advance to anyone who can offer some tips, advice, or pointers.
