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

"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."
"People should know that it is simple and advanced."
"We have found the solution to be stable."
"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."
"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."
"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."
"Icinga does the job and is fairly stable."
"The most valuable feature is the performance parameters of the system."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."
"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"We have used this product now for quite some time and we are happy with it."
"Dashboard provides monitor of total assets."
 

Cons

"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"It is not really adequate for our current needs. It causes additional issues which we have to work around and takes us time that a better solution would not."
"The installation and configuration are very complex."
"Icinga’s automation could be improved."
"Scalability is problematic. If you have a stable environment it's good, but if the environment is growing, I had some problems with Icinga."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"We have found some problems with Nagios, and support isn't very responsive."
"The user interface should be improved."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"I like to have the option to configure Nagios using the web interface."
"The UI is a little outdated and graphics could be displayed in a better way."
"The dashboard and monitoring features could be improved."
"The core version is no match for the XI version."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
