Senior System Administrator at Interactive Group
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.

Quotes from Members

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

Pros

"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."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"Provides timely notifications."
"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."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"We use the product to monitor server applications."
"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"The most valuable feature is that it is an all-in-one monitoring system."
"The network monitoring and configuration within this solution is very good."
"This solution has screens that are easy to understand and provide a wealth of information."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"It is easy to create your own custom modules if you just know a little bit of scripting. If you have unique requirements, you can just make your own modules. You can even grab checks from other vendors. There are open-source checks for various things such as SMTP, etc. There is a long list of different ones from Nagios. You can just use them, and within seconds, you get yourself a check that is monitoring whatever you need. It is really flexible. I guess that's why they call it Pandora Flexible Monitoring System (FMS). It is reliable. It does the job, and it alerts. It is also surprisingly feature-rich. Our network guy just recently asked about a particular protocol to monitor the bandwidth on the network, which is not a common protocol. When I looked it up, and I found that they cover it. It is very mature for a not-so-known product."
"You can configure several types of architecture for high availability or load balancing."
"Thanks to this software and to the work of the support team, we have everything under control."
 

Cons

"The tool needs to improve the integrations."
"Application level monitoring is limited."
"The scalability needs improvement, it's not scalable at this time."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"We would like the real-time monitoring of an interface to be improved within this solution."
"It would be helpful to include the generation of reports for times that the network was out of service."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"Third-party integration should be improved for some commonly used products."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"The product lacks APIs for integration with other systems."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
 

Pricing and Cost Advice

"We are using the free version."
"Nagios Core is free to use."
"The solution is expensive."
"We are using the open-source, unpaid version."
"The enterprise version has technical support. The version we are using is free."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"Most the plugin features are free."
"It's free."
"My rule of thumb would be that if you need more than thirty agents, and you lack an automation tool such as Chef or Puppet, you will save a lot of time and money going to the Enterprise edition."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
