Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The Centerity gives us exactly what we need from performance system monitoring."
"The machine learning feature is valuable."
"Centerity is much more than a monitoring tool — it’s a unified, end-to-end, enterprise-class and multi-tenanted AIOps Platform that is purpose-built to help MSPs and data-centers deliver the highest levels of up-time and performance."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"Provides timely notifications."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."
 

Cons

"They can improve the functionality that provides some numbers related to the behavior of the metrics."
"The GUI must be improved. Graphs must be changed including high level maps"
"One of the major improvements should be it implementation as a SaaS"
"There is room for improvement in the graphics."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"The mapping is a little hard."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."
"t was a little hard to get our setup represented in the configuration."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."

What needs improvement with Nagios Core?
The dashboard should be improved. It's very simple. I don't have a very clear or specific suggestion. You can change the skin of the dashboard, however, it's good for me.
What is your primary use case for Nagios Core?
