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."
"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."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"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 reporting structure and the feature set are valuable to me."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"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."
 

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."
"It is technical. The engineer must be familiar with it."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"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."
"The dashboard should be improved."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The configuration and reporting modules need to be improved."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"The interface could be improved."
