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

"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"I use it for monitoring infrastructure and it was very good for that issue."
"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."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"People should know that it is simple and advanced."
"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."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"I like the way the solution sends alerts and how it keeps on escalating them."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"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 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."
"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."
"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."
 

Cons

"The tool currently fails to provide notifications to users."
"The connection between Icinga and Icinga Web."
"Network Discovery capabilities would be extremely helpful."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"The solution lacks many features important to higher-level IT management and network support."
"The installation and configuration are very complex."
"Sometimes, it is very hard to keep an overview of what's happening."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"Application level monitoring is limited."
"The interface could be improved."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"Nagios' great customizability is also one of its greatest drawback."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"The dashboard and monitoring features could be improved."
"The scalability needs improvement, it's not scalable at this time."
"The mapping is a little hard."

What is your experience regarding pricing and costs for Nagios Core?
Nagios Core is a free and open-source product. We don't charge for the product itself, but we charge for the man-hour costs related to installation, configuration, ongoing operation, and maintenance.
