spending time with nagios to finetune

[Eduardo Moura]

People,

We run a 40 servers/450 services installation and spend 3 hours per month in
fine tuning. We have average 30 notifications per day, and less than 10% are
false posivites.
The secret? Tuning the critical/warning thresholds very carefully. In
ongoing operation you can learn how is the REAL critical/warning thresholds,
then adjust you nagios to them.

Best Regards

Hello nagios users.

We run about 50 hosts with approx 400 services to check (webservice 
apache/mail/mysql/mysql_replica/ftp/load/procs/disks/mailq/temp/backups).
Spending a lot of time to fine tune nagios, every day nearly 15-60 min , 
still we have 5 ~ 20 notifications a day.

I have some questions, how you run nagios.
How much time do you spend a day or week to run nagios ?
How much notifications a day do you have ?
Must be every notify a real allert or do you also have 80% notifications 
just for an annoying mobile telephone ring.
Would be interesting to hear your idea how you run nagios.


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.

Thanks in advance.
