"Nagios helps us monitor our network with ease"
4/5
What do you like best about Nagios Network Analyzer?

Very nice product for quick checks, easy to configure from server and client side, Open source..which can be a double edged sword, but at least you have options. Nagios operates well in large environments. Nagios website has most basics thoroughly documented for reference. Review collected by and hosted on G2.com.

What do you dislike about Nagios Network Analyzer?

All of the false positive alerts are annoying and time consuming to sift through from a technical support/help desk standpoint. It's a great tool but considering how many years it has been existing it barely evolved. By default every alert triggers a notification. it also does not support plotting graphs of the monitored values. Review collected by and hosted on G2.com.

"A Jack of all Trades"
4.5/5
What do you like best about Nagios Network Analyzer?

Malleability is Nagios' true strongpoint. I have seen it used in 3 fairly different environments. I've used 3 different frontends, currently using 2, to interact with the nagios backbone. Each having their own strengths and weaknesses respectively. When it comes to interacting directly with it via the CLI, while not the nicest to look at or work with, it does exactly what you tell it to. Review collected by and hosted on G2.com.

What do you dislike about Nagios Network Analyzer?

Directly editing configurations can sometimes be a bit of a process due to having to dig through the files in the terminal. You get out what you put in, and for most people the quality of their nagios experience will have to do with what front-end they end up putting in. Review collected by and hosted on G2.com.

"Works well, if a little clunky to set up."
4/5
What do you like best about Nagios Network Analyzer?

It monitors everything we threw at it. It can even tie into pagers (yes, old style beepers) to deliver notifications. Down time and maintenance notifications are easy to use. The add ons really make this product shine -- with the help of free libraries of addons and plugins online there is very little that can't be monitored by this software. Plus, the price is right! Review collected by and hosted on G2.com.

What do you dislike about Nagios Network Analyzer?

It can be a little clunky to configure -- manually editing text files in a CLI isn't exactly my idea of a great time. There are GUI plugins available, but I have yet to find one that works as well as simply editing the config files. Review collected by and hosted on G2.com.
