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

"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."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"We have used this product now for quite some time and we are happy with it."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"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 most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"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."
"Network monitoring is fun again with Pandora FMS."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"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."
"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. It's also scalable enough to support large environments."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"The solution has good dashboards and graphics."
 

Cons

"The dashboard and monitoring features could be improved."
"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."
"It is a bit slow due to latency."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"The alerting mechanism in Nagios Core could be improved."
"The core version is no match for the XI version."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"We would like the real-time monitoring of an interface to be improved within this solution."
"We would like the real-time monitoring of an interface to be improved within this solution."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"It would be helpful to include the generation of reports for times that the network was out of service."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
 

Pricing and Cost Advice

"Most the plugin features are free."
"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."
"We are using the free version of Nagios Core."
"We are using the open-source, unpaid version."
"Nagios Core is a cheap solution."
"Lessening the price point would be an improvement."
"Nagios Core is free to use."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
