Pros

"The Centerity gives us exactly what we need from performance system monitoring."
"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 most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"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."
"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"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."
"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"Nagios Core is very configurable. Whatever you want, you can do it."
"The solution is very complete and mostly easy to manage."
