Easy to use, and it's possible to customize the product as per the needs we may have but average multi-tenancy aspect
It's supported by the community. We use Icinga, which is not part of the Open-Source platform but is wrapped into a commercial solution from another provider, a local provider in Italy. Icinga is an open-source platform, so it is supported by the community. It's quite easy to use, and it's possible to customize the product as per the needs we may have. So it's not expensive, and it's quite a general purpose. We can easily monitor any kind of infrastructure we encounter. The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated. The alerting is the same as any other monitoring platform. It's not a "wow" feature that has changed our lives, but it's perfectly adequate.

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

"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"Macros and the ability to connect it to Google Maps are valuable features."
"The apply rules feature saves a lot of time."
"An affordable solution for small organizations to do basic network monitoring."
"We have found the solution to be stable."
"I would recommend Icinga; it's an open-source solution, it's quite easy and simple to use, and checks can be run with Python code and Shell Script code."
"If you have a small infrastructure or a small number of devices that you want to monitor, then I think it's a good solution."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"We use the product to monitor server applications."
"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."
"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."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"Dashboard provides monitor of total assets."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
 

Cons

"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"The user interface should be improved."
"Icinga is a complex solution that's hard to learn. It's a powerful product for monitoring, but new users will have a hard time figuring out what to do."
"Sometimes, it is very hard to keep an overview of what's happening."
"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."
"The solution lacks many features important to higher-level IT management and network support."
"The tool currently fails to provide notifications to users."
"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"Nagios' great customizability is also one of its greatest drawback."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"Application level monitoring is limited."
"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."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"t was a little hard to get our setup represented in the configuration."
"I would like to see more training videos."
"The alerting mechanism in Nagios Core could be improved."
