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

"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 most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"The features of Nagios Core that we find most valuable are the plugins we use, we can check the uptime and see how many servers and routers and create groups accordingly."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"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."
"Provides timely notifications."
"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

"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."
"The interface could be improved."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"It is a bit slow due to latency."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"The dashboard and monitoring features could be improved."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"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."

"The enterprise version has technical support. The version we are using is free."
"We are using the free version of Nagios Core."
"We are using the free version."
