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

"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."
"One of the valuable features of this site is that it operates 24/7, monitoring my entire infrastructure, uptime, and related error issues."
"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"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."
"Nagios Core is very configurable. Whatever you want, you can do it."
"The application performance monitoring feature is valuable."
"The reporting structure and the feature set are valuable to me."
"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."
"The solution is very complete and mostly easy to manage."
 

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 initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The UI is a little outdated and graphics could be displayed in a better way."
"There is room for improvement in the graphics."
"I like to have the option to configure Nagios using the web interface."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
