Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

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

"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"The solution is pretty stable."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"The ROI is very good."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"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."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"What I value most about Pandora FMS is the simplicity of working with it."
"Stability is where they shine. It has been super stable. We have high-end monitoring for our data centers. We monitor all kinds of metrics in our two data centers. We monitor maybe over 2,500 checks, and the product that has been successful and always alerting us is Pandora."
 

Cons

"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
"Technical support is an area that needs improvement. It is not available 24/7."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"Nagios XI doesn't provide scripting. For example, if we have built up multiple IPX tunnels from a base location to a data center location and want to monitor or trigger an alert if the tunnel goes down, Nagios XI does not automatically send alerts notifying us that the tunnel is down."
"For some, it may be difficult to deploy."
"There's room for improvement in the visibility, and in the ability to extract information."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"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."
"In the future, we may have double the number of devices, and we do not want to have any issues with performance in the data display."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"We would like the real-time monitoring of an interface to be improved within this solution."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"Pandora FMS is relatively new, and the interface with the older version crashes at times."
 

Pricing and Cost Advice

"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is open source."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"Licensing costs are reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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 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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
