That really sounds excessive. We monitor hundreds of hosts and thousands of routers and have only have a handful of alerts a week. Are you taking the time to correct the error conditions such that they don't happen again or happen only rarely? That's the biggest step you can take in reducing the number of alerts you receive. The second is to be sure that you're monitoring things that really are important. > I have some questions, how you run nagios. > How much time do you spend a day or week to run nagios ? Measured in minutes or less. I presume you mean tuning or other. I rarely have to touch the system at all. 95% of our config generation is automated out of our customer databases so there's little that I need to do there. There are a handful of special case host monitoring that we're doing that I have to modify every once in a while but it's very rare. > How much notifications a day do you have ? A handful a week, mostly due to Telco circuit issues that we have little control over (we monitor >5000 circuits). > Must be every notify a real allert or do you also have 80% notifications > just for an annoying mobile telephone ring. Not sure about this but it sounds like it would depend on the criticality of the service that you're monitoring. For our circuit notifications, we don't send email alerts if there is at least one circuit up at a multi-circuit site. Same with our load balanced servers. If they're all down or there's not redundancy at all, then that's usually alertable. > Nagios helped me a lot with uptime on my servers. > No diskfull errors, no unknown downtime anymore and more happy customers. > I'ts Better to spend time on nagios than fixing problems. Nagios can help a great deal in determining where you aren't being proactive enough in preventing problems. As you work through those cases you'll find that your systems are more reliable and you'll have fewer and fewer notifications. -- Marc ------------------------------------------------------------------------- Take Surveys.
