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."
"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."
"Site24x7 stands out. It is truly amazing."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"Dashboard provides monitor of total assets."
"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."
"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."
"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."
"The reporting structure and the feature set are valuable to me."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"We use the product to monitor server applications."
 

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."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"The interface could be improved."
"They should simplify the features so it becomes easier to setup out of the box."
"The configuration and reporting modules need to be improved."
"The initial setup process could be easier."
"The dashboard should be improved."
"I like to have the option to configure Nagios using the web interface."
"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."
