Nagios Core Review

When any part of the system went down, it would inform us right away with alerts. In most cases, we were able to find the problem before the client did.


What is most valuable?

The most valuable feature of Nagios is its monitoring capability. Once you configure it correctly, it will help you monitor all your servers and services.

How has it helped my organization?

When working on ISPs, we used Nagios to monitor all our servers and network switches in the entire city. When any part of the system went down, Nagios would inform us right away with alerts. In most cases, we were able to find the problem before the client did.

What needs improvement?

We use the free version of Nagios, which needs some administrative skills in order to configure correctly. It would be great to see some of the paid features in the free version, such as web-based administration.

For how long have I used the solution?

I've used Nagios since 2008 year, and I'm really pleased with it. It helps me a lot with my system administrator work. I used it on my local servers initially, then I started to work at an ISP where I implemented Nagios. It's still in use there.

What was my experience with deployment of the solution?

I rarely upgrade Nagios as everything works fine. I've had no issues deploying it.

What do I think about the stability of the solution?

I've had no stability issues. It's been very stable.

What do I think about the scalability of the solution?

There have been no issues scaling it.

How are customer service and technical support?

I've never used tech support and I find all my answers on Google or forums.

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

I tried Zabbix and OpenNMP but I didn't like them. I use Cacti and SmokePing for detailed graphics.

How was the initial setup?

A few years ago, the initial setup was complex, but now it's not. It just has some config files where you should add your host. Everything is written in the documentation.

What about the implementation team?

I implemented it by myself.

What other advice do I have?

You should really try Nagios. It will help a lot and I have found that it is the best buddy for system admins.
