Nagios Core Review

Large ecosystem of tools, but default interface is clunky and slow.

Valuable Features:

Open source and very flexible. large ecosystem of tools and custom monitors built up around nagios. All configuration is text files, so it is easy to keep this in version control and generate new configs from other tools.

Room for Improvement:

Default interface is clunky and slow. Can be a steep learning curve if you haven't worked with it before. Adding devices or services requires reloading the config or restarting the service. Would like for this to be more dynamic. It seems that most of the new development is going towards Nagios XI(paid enterprise version) rather than the opensource nagios. Would like to see some of the newer ideas in Icinga and/or MK livestaus integrated into opensource nagios.

The UI isn't slow, it would only be slow if the underlining OS hasn't been giving a descent amount of resources.

Yes learning Nagios is difficult but once you learn its full potential, I'm sure anyone will benefit from what Nagios has to offer.

If you integrate nagios into software/apps such as Centreon or NagioSQL then dynamic monitoring can be achieved.

I think its a brilliant piece of kit, once you know what its capable of you can customise it to your needs and also for free.
