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."
"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"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."
"The poller is really good, I can easily implement new stuff and it is scalable."
"We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it."
"The application performance monitoring feature is valuable."
"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."
"The solution is very complete and mostly easy to manage."
"The most valuable feature is the performance parameters of the system."
 

Cons

"The GUI must be improved. Graphs must be changed including high level maps"
"They can improve the functionality that provides some numbers related to the behavior of the metrics."
"One of the major improvements should be it implementation as a SaaS"
"The tool needs to improve the integrations."
"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."
"There is room for improvement in the graphics."
"Default interface is clunky and slow."
"Generally, it does what I need it to do, but better error reporting would be great."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"The initial setup process could be easier."
"Nagios Core is not easy to use, so I don't recommend it for everyone."

What is your experience regarding pricing and costs for Nagios Core?
Nagios Core is a free and open-source product. We don't charge for the product itself, but we charge for the man-hour costs related to installation, configuration, ongoing operation, and maintenance.
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?
I was a senior system administrator. I've been using Nagios Core for more than ten years now. It can be used to monitor hosts, such as machines, and monitor services of any kind. I'm using it to mo...
