Efficient and easy to manage with good stability

What is our primary use case?

We primarily use the solution for monitoring ops for computers and our server. We're considering adding other device monitoring as well and at points of sale.

Pros and Cons

  • "The solution is quite efficient."
  • "It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."

What other advice do I have?

We're just customers and end-users. We don't have a business relationship with Nagios. We're using the latest version of the solution. We're still in the early days in terms of usage. We're still feeling the solution out and testing it for its acceptability within the greater framework of our organization's requirements. We're looking to test it at the point of sale to see how successfully it operates. Overall, I would recommend the solution to other organizations. I would rate the solution eight out of ten.

Open-source, good reporting and online documentation, but the GUI needs improvements

Pros and Cons

  • "The most valuable features are the reports and the way it generates the report in a graphical manner."
  • "The scalability needs improvement, it's not scalable at this time."

What other advice do I have?

I would recommend it for small network deployments or if you have other open source applications or other metrics like utilization, CPU. So if you're running alongside other open source applications and in the small space, it works. But anything beyond that is not recommended. I would rate Nagios Core a six out of ten.
