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

"Site24x7 stands out. It is truly amazing."
"One of the valuable features of this site is that it operates 24/7, monitoring my entire infrastructure, uptime, and related error issues."
"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."
"Inspite of this limitation it is a fantastic product to use at zero cost"
"I would rate the overall solution ten points out of ten."
"We've got a medium size distributed system with a lot of locally installed machines, and Nagios provides us with a solid and reliable monitoring solution for these machines."
"The solution is quite efficient."
"The solution is very complete and mostly easy to manage."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"We use the product to monitor server applications."
"The good thing about Nagios Core is it covers everything."
 

Cons

"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."
"The product is not difficult to use. That said, it is technical. The engineer must be familiar with it."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"The mapping is a little hard."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."
"Generally, it does what I need it to do, but better error reporting would be great."
