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."
"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."
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"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 tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."
"The reporting structure and the feature set are valuable to me."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
 

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"
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"The alerting mechanism in Nagios Core could be improved."
"Nagios' great customizability is also one of its greatest drawback."
"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."
"Generally, it does what I need it to do, but better error reporting would be great."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"Default interface is clunky and slow."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
