Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

A highly stable solution that can be used to monitor system availability
The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup. You can clone that service, and it allows you to add new services quickly. You can bring up new servers, and you can easily add them. Also, there's an API to be able to add services as well. We don't use the API. We mostly use the cloning function because it stores everything in a back-end database. The underlying monitoring platform for our version is Nagios. That's where we upgraded from Nagios to Opsview.

Enables seamless global client monitoring with reliable remote connectivity
I use the solution to provide a perfect environment for remote connectivity with my clients. Many tools that I require for system maintenance are included. I can easily monitor all of my clients throughout the world I did not give much thought to it, however, improvements could be made to Zabbix.…

Quotes from Members

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

Pros

"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"The solution is quite efficient."
"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."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"Dashboard provides monitor of total assets."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"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."
"I am satisfied with the overall product since it works well…It is a stable solution."
"The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup."
"It's a good solution. It covers all aspects of monitoring purposes."
"We use this solution for internal monitoring our own cloud platform because we are a public cloud provider. We also use it for monitoring purposes on behalf of our clients."
"What was very compelling about OpsView was that we could dial out the noise and have meaningful and actionable alerts."
"It's one of the best products available."
"The most valuable feature is the monitoring of virtual machines."
"It has improved our server performance monitoring overall. We know right away when there are problems. It has built-in statistics, so we can go back and see if there's spiking. We can check what's happening every day around the same time and check the configuration to see if there's something that's running and needs to be fixed."
"In terms of customization and integration, we have more flexibility. We can automate configurations, define deletion rules, and customize based on the needs. The client interface allows for further configuration, making it quite comprehensive."
"The integration capabilities and APIs are the best part."
"Like other common Linux distributions, some of the most valuable features of this solution are the ease of use and deployment. It's simple and has a lot of packages and a lot of software."
"The solution's design has recently changed and it is visually pleasing with more color, for example, there is blue, black, and white."
"Health and communication links availability."
 

Cons

"The initial setup process could be easier."
"Nagios Core does not have a graphic display."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The interface could be improved."
"The tool needs to improve the integrations."
"It is a bit slow due to latency."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"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."
"Pricing and a few certain aspects in the solution needs to be improved."
"Maybe the graphical representation can be improved. It can be enhanced for better visualization. It could be a little better. And the graph center can be improved."
"In a future release, we would like to have Observ for AI. Any AI and intelligence it can add to the monitoring is obviously beneficial. We would also like to have automated callouts."
"Some of the graphics on Opsview could be improved."
"Customized reporting can be improved."
"The server monitoring could be better."
"The APM monitoring has room for improvement, although I hear that the new 5.2 version has some improvements in that area, and I'd like to give that a go. I would like to see a few more templates out there for different styles of monitoring. I use the Grafana interface for reporting. I would also like it to have an out-of-the-box ability to email reports. You can create reports, but to be able to email those reports would be really helpful. I've got users who are not interested in logging in and generating a report. They want it all pre-canned and sent to an email address. It would also be really handy if we could pin certain reports up onto platforms such as Teams or SharePoint. A GUI for the proxy server would be cool to have for debugging purposes and for the support teams to have a look at, but I don't know whether that's really feasible to do. I get enough from the log files themselves."
"Improvement is needed as per customer requirements."
"My company wanted to do an exercise command to access IT from Cameroon. They wanted to access an FSS to a second host with second equipment that was on another coast but it is not possible on Zabbix to do it. They want to directly access from the front-end of Zabbix to access a prompt in Zabbix to an access terminal. In the front-end, there is no way to do that. That would be an important improvement."
"One of the things we don't like is that Zabbix has a license structure with a price that is high compared to the competition. It's very high, for example, compared to something like Microsoft Teams."
"Implementing Zabbix is difficult. I've deployed many solutions over the years, and Zabbix is the hardest to implement. You have to do some development to get it to work with IBM, Micro Focus, or HP products."
"I would like to remotely connect to the computer, and Zabbix doesn't have this capability."
"Zabbix can use better documentation and support for troubleshooting."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
