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."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"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."
"Extensibility is good as this makes it easy to write checks on your own."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
 

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."
"Application level monitoring is limited."
"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."
"The core version is no match for the XI version."
"This is the open source product, so it's a toolkit rather than a complete solution."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"We're using the free version, which limits us in terms of the things that we can do."
"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."
"The tool needs to improve the integrations."
 

Pricing and Cost Advice

What needs improvement with Nagios Core?
