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.

High performance, quick packet monitoring, and helpful support
The solution could improve by having automatic mitigation. For example, as soon as a problem occurs the solution alarms and mitigates the situation immediately. In a feature release of the solution they should add features related to automation and remediation. Automation would help increase level of security the solution provides.

Quotes from Members

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

Pros

"Extensibility is good as this makes it easy to write checks on your own."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"We can get real time statistics of our servers which improves our monitoring."
"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."
"We've got a medium size distributed system with a lot of locally installed machines, and Nagios provides us with a solid and reliable monitoring solution for these machines."
"I like the way the solution sends alerts and how it keeps on escalating them."
"The application performance monitoring feature is valuable."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"NIKSUN provides you with the why, what, when and where type of answers to all your network problems."
"The most valuable features of NIKSUN NetVCR are its performance and forensic capabilities. Additionally, the information that the solution provides is highly detailed and useful. When dealing with network traffic packets can be sent at a high speed causing some security issues, but this solution is able to rapidly monitor the packets providing security."
"The unique selling point of NIKSUN is its ability to scale and its reporting capabilities. NIKSUN captures the packets at a very high speed, from one GB to 160 Gbps also. It offers report granularity in nanoseconds."
 

Cons

"There is room for improvement in the graphics."
"The dashboard and monitoring features could be improved."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"t was a little hard to get our setup represented in the configuration."
"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."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"The solution could improve by having automatic mitigation. For example, as soon as a problem occurs the solution alarms and mitigates the situation immediately."
"NIKSUN is a passive solution. It provides you with you data, alerts, reports and the root cause of issues. However, it requires a person to make use of this functionality. If an event is happening and nobody attends to it, the effects of the event could be severe."
 

Pricing and Cost Advice

"I would rate the solution's pricing an eight out of ten."
"Nagios Core is free to use."
"Most the plugin features are free."
"We are using the free version."
"It's free."
"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 open-source, unpaid version."
"The product is cheaply priced."
"The price of the solution is high. There is an annual license costs."
