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

"Icinga does the job and is fairly stable."
"An affordable solution for small organizations to do basic network monitoring."
"The apply rules feature saves a lot of time."
"The most valuable feature is one that not many are even aware of, as Icinga has a self-healing event handler where if the service is down, it is automatically restarted, and you can configure the handler to take action after the critical alarm without human interaction."
"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."
"Macros and the ability to connect it to Google Maps are valuable features."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"Nagios Core is very configurable. Whatever you want, you can do it."
"We use the product to monitor server applications."
 

Cons

"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."
"The connection between Icinga and Icinga Web."
"The installation and configuration are very complex."
"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."
"Sometimes, it is very hard to keep an overview of what's happening."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"The tool currently fails to provide notifications to users."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"We're using the free version, which limits us in terms of the things that we can do."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"The tool needs to improve the integrations."
"Generally, it does what I need it to do, but better error reporting would be great."
"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."
"Lessening the price point would be an improvement."
