Anybody has experience with cacti and nagios?

Hi! :) Nagios+MRTG for monitoring mi little network!(FreeBSD 5.4) and it work very well; list of devices to monitoring:

3 Routers
2 Windows 2000 servers
1 Windows 2003 AS
1 Linux SuSE Server
2 RHEL AS Server
1 Trixbox Server
24 Windows XP

And i have not experienced problems at least.

    Good Day.

    PS. Sorry, my english is very, very poor.

Don't apologize for knowing two languages, your english is fine ;^)

We use both Nagios and Cacti because they really do two different things. We use Nagios to monitor availability as it can do active checks of services, such as checking if http is up. It can also accept passive checks from other systems such as MySQL when MySQL is not listening on TCP. The remote machine checks locally for services, or disk space, etc and reports back to the Nagios machine. Nagios is very configurable as to how and when it alerts you to a potential problem. Nagios though will not record such things as interface statistics with historical data.

We use Cacti to monitor status as it retains history which can be 'drilled down' into, it may even do alerts but we have not investigated that yet. We use Cacti to maintain historical data on interface availablity, bandwidth useage, and soon queue sizes, and web directory sizes.

Both are very configurable, and I think, make a good team for overall network monitoring and recording. We currenly monitor 12 servers for http, https, up status, https cert, ssh, smtp, pop, smtp-auth, ftp, radius, dns, and custom tests such as OSCommerce. We monitor 20+ routers and other equipment for useage.

Read the docs for each and experiment, there is a lot they can do.


Three years now I've asked Google why they don't have a
logo change for Memorial Day. Why do they choose to do logos
for other non-international holidays, but nothing for

Maybe they forgot who made that choice possible.
