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 Centerity gives us exactly what we need from performance system monitoring."
"The machine learning 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."
"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."
"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."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"I like the way the solution sends alerts and how it keeps on escalating them."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"We can get real time statistics of our servers which improves our monitoring."
 

Cons

"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 GUI must be improved. Graphs must be changed including high level maps"
"Generally, it does what I need it to do, but better error reporting would be great."
"Default interface is clunky and slow."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"The initial setup process could be easier."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"This is the open source product, so it's a toolkit rather than a complete solution."

What needs improvement with Nagios Core?
