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.

Cost effective but when we originally purchased LANGuardian, some features needed further development.

Quotes from Members

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

Pros

"Inspite of this limitation it is a fantastic product to use at zero cost"
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"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."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"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."
"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."
"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."
"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."
"If you are looking for a solid solution that can be easily deployed then I'd recommend considering Netfort solutions."
"Our CIO asked us to track down the source of undesired uploads, which trigger e-mails received by outside bodies regarding what they refer to as "copyright violations", and Languardian was the most efficient and effective tool for the job."
 

Cons

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"The mapping is a little hard."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."
"Nagios Core does not have a graphic display."
"The dashboard should be improved."
"The alerting mechanism in Nagios Core could be improved."
"Sure, at the time we bought the product, the GUI and graphs/reports/pie charts etc ... were not fully developed."
"It takes a long time to load results. I think it would be great if they fix the slowness issue in the next release."
 

Pricing and Cost Advice

"Most the plugin features are free."
"The solution is expensive."
"Nagios Core is a cheap solution."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"We are using the free version."
"We are using the open-source, unpaid version."
"It's free."
"I would rate the solution's pricing an eight out of ten."

Questions from the Community

What needs improvement with Nagios Core?

What is your primary use case for Nagios Core?
