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

"The Script Module in Nagios is really easy to use and is really cost efficient."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"It's great for monitoring IT services infrastructure."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"Nagios XI allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"The solution has a lot of plugins and scripts integrated with it."
"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. It's also scalable enough to support large environments."
"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."
"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 provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"This solution has screens that are easy to understand and provide a wealth of information."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
 

Cons

"There's room for improvement in the visibility, and in the ability to extract information."
"Nagios XI can improve its GUI for users with a new look."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The user interface needs improvement."
"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 very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"I think some improvements to the Android app would be good."
"Improvements are needed for server and network discovery, including service-based discovery."
"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 think some improvements to the Android app would be good."
"It would be helpful to include the generation of reports for times that the network was out of service."
 

Pricing and Cost Advice

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is an expensive solution."
"Licensing costs are reasonable."
"We are using the free version of this solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"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."
"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 version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
