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

Pros

"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."
"The good thing about Nagios Core is it covers everything."
"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."
"The solution is quite efficient."
"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."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"Nagios Core is stable."
"The features of Nagios Core that we find most valuable are the plugins we use, we can check the uptime and see how many servers and routers and create groups accordingly."
"The network monitoring and configuration within this solution is very good."
"We are able to control our business with this all-in-one monitoring tool."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"Pandora's architecture is interesting; it's open so you can easily extend and enhance it, it's simpler to customize Pandora compared to other solutions, and it's also scalable enough to support large environments."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"The solution has good dashboards and graphics."
 

Cons

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"The mapping is a little hard."
"We're using the free version, which limits us in terms of the things that we can do."
"The user interface could be more interactive because it is pretty basic."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"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."
"Application level monitoring is limited."
"The core version is no match for the XI version."
"The price for Pandora FMS is expensive."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"A nice feature in the next release would be an automation module to run workflow actions."
"It would be helpful to include the generation of reports for times that the network was out of service."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"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."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
 

Pricing and Cost Advice

"The product is cheaply priced."
"It's free."
"The enterprise version has technical support. The version we are using is free."
"Nagios Core is an open source solution, and there are no licensing fees."
"We are using the free version."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is a cheap solution."
"Lessening the price point would be an improvement."
"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."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
