Nagios Core Review

I can see trends over time and it gives me perspective of what needs to be improved and we are able to work proactively as opposed to reactively.


What is most valuable?

Getting the alerts is the most valuable feature. This way I know when servers are acting up or just plainhosed. It also helps me to know which things need to be recovered and when so I do not have to bother with checking into it immediately.

How has it helped my organization?

Before we implemented Nagios, we did not know which servers were up or down until a customer told us. Now, I can see trends over time and it gives me perspective of what needs to be improved and we are able to work proactively as opposed to reactively.

What needs improvement?

Generally, it does what I need it to do, but better error reporting would be great. It's so flexible that I do not use half the capability that it has. Also, Nagios 4 does not work with NConf or Adagios so we haven't upgraded yet.

For how long have I used the solution?

I have worked with it as a monitoring and alerting solution for 10 years accross two jobs.

What was my experience with deployment of the solution?

We have had no issues with the deployment.

What do I think about the stability of the solution?

There have been no performance issues.

What do I think about the scalability of the solution?

We are monitoring under 200 devices and less than 1200 services so I do not need this availability yet.

How are customer service and technical support?

I've never needed to contact the vendor as I have always found my answers via the documentation and Google searches.

Which solution did I use previously and why did I switch?

I have used Zabix and Big Brother, but neither was as workable as Nagios.

How was the initial setup?

Setup is not for the GUI lover as it requires you to perform a lot of CLI work.

What about the implementation team?

You do not need a vendor. I have always deployed it myself.

What's my experience with pricing, setup cost, and licensing?

It's free.

Which other solutions did I evaluate?

I have looked at other solutions but none are as simple, and I would hate to have to learn another system.

What other advice do I have?

It's well worth it to ensure your up time and to catch the bigger issues.
