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."

"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."

"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."

"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."

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."

"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"

"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."

"Nagios Core is very configurable. Whatever you want, you can do it."

"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."

"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."

More Nagios Core pros

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"

"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."

"Application level monitoring is limited."

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"Generally, it does what I need it to do, but better error reporting would be great."

Overview

Centerity is the pioneer provider of an All-in-One, IT Monitoring and Business Service Management (BSM) platform.

Centerity’s unique, unified platform, named a Gartner Cool Vendor in ITOM, can serve the needs of both IT executives and administrators while providing a complete business intelligence layer across all IT assets via cross technical and functional domain impact and trend analysis through its Business Service Management (BSM) capabilities.
