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.

A cost-effective solution to monitor customer networks
We are not getting any issues with the integrations. Versa Director is the fastest engineering tool and is ideal for use without product management. People must rely on and utilize it to enhance anything they want to increase, as it helps minimize the product. Overall, I rate the solution a nine out of ten.

Quotes from Members

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

Pros

"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."
"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."
"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."
"I would rate the overall solution ten points out of ten."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"I like the way the solution sends alerts and how it keeps on escalating them."
"The reporting structure and the feature set are valuable to me."
"The most valuable functionality is some of the policy pieces that are quite useful."
"Versa Director is the fastest engineering tool and is ideal for use without product management."
"Versa Director has easier customer reports, utilization monitoring, graphic shaping monitoring, configuration, template shaping, and deduplication compared to Fortinet and Cisco."
"The most valuable feature of Versa Director is analytics."
"I think the most valuable functionality is some of the policy pieces that are quite useful."
"Versa Director is a beneficial product for the environment my company has."
"Versa Director's best feature is the ease of configuration and customer and vendor management."
 

Cons

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"Nagios' great customizability is also one of its greatest drawback."
"Lessening the price point would be an improvement."
"The alerting mechanism in Nagios Core could be improved."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"Application level monitoring is limited."
"I think the one area that could be improved is that there are a lot of features; that is also an advantage but it makes things a little difficult, so I'd like to see some simplification so that there is less bloat."
"Versa Director's on-prem SD-WAN hardware and SSL VPN software are not integrated, so you have to buy a separate subscription for the SSL VPN."
"Versa could be more AI-oriented."
"What needs improvement in Versa Director is maturity because, from an operating point of view, it's not mature enough. You'll still need to do a lot of research on Versa Director, so if it could mature faster, that would be very good."
"It requires some simplification."
"Versa Director's deployment process is not the best."
"What needs improvement in Versa Director is maturity because, from an operating point of view, it's not mature enough."
 

Pricing and Cost Advice

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is an open source solution, and there are no licensing fees."
"Lessening the price point would be an improvement."
"It's free."
"Most the plugin features are free."
"I would rate the solution's pricing an eight out of ten."
"It's free."
"Having to buy separate licenses for the on-prem SD-WAN hardware and SSL VPN software makes Versa Director very costly compared to other solutions like Fortinet and Cisco."
