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.

The open architecture is easy to extend and enhance
Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Quotes from Members

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

Pros

"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."
"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."
"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"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."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"Network monitoring is fun again with Pandora FMS."
"This tool has been of great help because we can manage faster solutions with the problems in our network and it helped us reduce our response time."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"The most valuable feature is that it is an all-in-one monitoring system."
"This solution has screens that are easy to understand and provide a wealth of information."
 

Cons

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."
"t was a little hard to get our setup represented in the configuration."
"The interface could be improved."
"The mapping is a little hard."
"The UI is a little outdated and graphics could be displayed in a better way."
"I like to have the option to configure Nagios using the web interface."
"Their support is good, but it is just online communication. It would be great to be able to just call someone and talk to them instead of always writing. It works well for me because I am a decent communicator in email, but some people might find it difficult to describe in a written fashion and communicate with them that way. There is a learning curve to the interface, but once you get used to it, it is actually very powerful. They have a lot of options, but people struggle with the interface. They've improved it though, and it is getting better. They need to keep improving the learning curve to help buy-in. I'm the guy that manages it, so I'm comfortable with it. They can refine the upgrade agents to be easier. They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way. It has a complete GUI and everything."
"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 price for Pandora FMS is expensive."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"It would be helpful to include the generation of reports for times that the network was out of service."
"I think some improvements to the Android app would be good."
"An update to the Android app would be appreciated."
"I find that this software is resource heavy, and demands a lot of processing capacity."
 

Pricing and Cost Advice

"We are using the free version."
"I would rate the solution's pricing an eight out of ten."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"The solution is expensive."
"It's free."
"We are using the open-source, unpaid version."
"Nagios Core is free to use."
"Most the plugin features are free."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"You have to pay for the number of agents and models that you are monitoring. I would rate the cost at three with one being the most expensive and five being the cheapest."
"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."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
