So I finally bit the bullet and jumped onboard the Nagios rollercoaster last week. I've always been a Windows Admin and had very, very little to do with Linux. As a 'Network Admin' who deals primarily with Education customers, they all use and have extroadinaly good Microsoft Licencing - so much so, that the cost of the software for my clients is taken out of the equation when they look at Windows Vs Linux. Anyway - this isn't a software windows vs linux thread... So now I'm learning Nagios. And Ubuntu. And I'm confused. I have my installation up now though, and its monitoring 14 servers quite nicely with my Email Alerts working too! First impressions - I'm finding Nagios (and Ubuntu) well documented. The offical doco is clear and concise however i find on occasions they assume I know more than I actually do. Overall - I like it though. Nagios though, to use its full potential appears to need a few 3rd party plugins. These are troublesome - I find the documentation often assumes I know alot more than I actually do. And often I find what doco that their is, confusing and sometimes contradictory, or in a foreign language... Who else is using Nagios? Recommend any plugins?
