Struggled with complex licensing and limited support but have gained unified cloud monitoring
We face certain challenges with monitoring website uptime for our business operations because we don't have that 24/7 monitoring, so that's what we are working with ManageEngine on, regarding how effectively we can use that. I may not be able to give that information on how ManageEngine Site24x7 can be improved, but I felt that the monitoring or the licensing terms, such as the advanced monitors or monitors, are not very user-friendly. I feel that because I don't know how exactly we can check what devices use which license and how we can control those things; that's not user-friendly. For example, if I have to look at what all devices are utilizing my advanced monitor license or what all devices are using my basic monitor license, then if I want to pull a report or validate them, I don't have an easy option; it's too complicated.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One of the valuable features of this site is that it operates 24/7, monitoring my entire infrastructure, uptime, and related error issues."
"Site24x7 stands out. It is truly amazing."
"The deployment was not a challenge for us, because we are just trying to connect to the cloud instance; it's SaaS-based, so we just had to route all our traffic to that particular device."
"We use the product to monitor server applications."
"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."
"The solution is quite efficient."
"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."
"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."
"Nagios Core is stable."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"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."
 

Cons

"The product is not difficult to use. That said, it is technical. The engineer must be familiar with it."
"The only complaint I would state about the technical support by ManageEngine is we don't get them on call; it's only email support that we get."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"We're using the free version, which limits us in terms of the things that we can do."
"The UI is a little outdated and graphics could be displayed in a better way."
"Nagios' great customizability is also one of its greatest drawback."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"The configuration and reporting modules need to be improved."
"The initial setup process could be easier."
 

Pricing and Cost Advice

Information not available
"Most the plugin features are free."
"The enterprise version has technical support. The version we are using is free."

"We are using the free version of Nagios Core."
"The solution is expensive."
