Quotes from Members

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

Pros

"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 machine learning feature is valuable."
"The Centerity gives us exactly what we need from performance system monitoring."
"The reporting structure and the feature set are valuable to me."
"The most valuable feature is the performance parameters of the system."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues, and it has helped to reduce downtime in the production environment to almost zero so we now spend less time on network or server administration."
"Nagios Core is stable."
"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."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"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."
 

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 initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"t was a little hard to get our setup represented in the configuration."
"I would like to see more training videos."
"The mapping is a little hard."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"They should simplify the features so it becomes easier to setup out of the box."
"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."
 

Pricing and Cost Advice

"Nagios Core is free to use."
"We are using the free version of Nagios Core."

What needs improvement with Nagios Core?
