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

"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."
"Nagios Core is very configurable. Whatever you want, you can do it."
"The good thing about Nagios Core is it covers everything."
"The reporting structure and the feature set are valuable to me."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"Nagios Core is stable."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."
"You can configure several types of architecture for high availability or load balancing."
"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."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"The most valuable feature is that it is an all-in-one monitoring system."
"Network monitoring is fun again with Pandora FMS."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
 

Cons

"Lessening the price point would be an improvement."
"The initial setup process could be easier."
"I like to have the option to configure Nagios using the web interface."
"The core version is no match for the XI version."
"It is a bit slow due to latency."
"Application level monitoring is limited."
"The tool needs to improve the integrations."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"Improvements are needed for server and network discovery, including service-based discovery."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"It would be useful if Pandora FMS included an ISO image (or «software appliance») for each big company that leases virtual private machines (VPS), just like in AWS."
"I think some improvements to the Android app would be good."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"This solution requires proper training to get 100% out of it."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
 

Pricing and Cost Advice

"We are using the free version of Nagios Core."
"Nagios Core is a cheap solution."
"Nagios Core is an open source solution, and there are no licensing fees."
"Nagios Core is free to use."
"Lessening the price point would be an improvement."
"It's free."
"The product is cheaply priced."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"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."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
