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

"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"The poller is really good, I can easily implement new stuff and it is scalable."
"The good thing about Nagios Core is it covers everything."
"I like the way the solution sends alerts and how it keeps on escalating them."
"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."
"NIKSUN provides you with the why, what, when and where type of answers to all your network problems."
"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

"The tool needs to improve the integrations."
"The dashboard and monitoring features could be improved."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"I like to have the option to configure Nagios using the web interface."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"It is a bit slow due to latency."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"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."
"The solution could improve by having automatic mitigation. For example, as soon as a problem occurs the solution alarms and mitigates the situation immediately."
