Quotes from Members

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

Pros

"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."
"The Centerity gives us exactly what we need from performance system monitoring."
"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"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."
"Provides timely notifications."
"The good thing about Nagios Core is it covers everything."
"Its an awesome product to use."
"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
"We've got a medium size distributed system with a lot of locally installed machines, and Nagios provides us with a solid and reliable monitoring solution for these machines."
 

Cons

"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"
"They can improve the functionality that provides some numbers related to the behavior of the metrics."
"We're using the free version, which limits us in terms of the things that we can do."
"Nagios' great customizability is also one of its greatest drawback."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"The dashboard should be improved."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
"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."
"Generally, it does what I need it to do, but better error reporting would be great."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
