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

"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The alerting system is very effective."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"The solution is pretty stable."
"Nagios XI is a simple monitoring tool with performance management."
"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."
"The support is excellent for this product; their response time is very fast, and they are very knowledgeable."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"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 is so lightweight that with only 4GB of ram, it allows keeping track of up to two hundred agents from a single console."
"Thanks to this software and to the work of the support team, we have everything under control."
"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."
"Thanks to this software and to the work of the support team, we have everything under control."
 

Cons

"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"WebUI should be improved (visual aspect) and should incorporate non-relational databases."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end."
"I feel that the maturity and user interface needs to be improved."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"There's no convenient way to manage notes as the only way is to manage them through the database."
"Improvements are needed for server and network discovery, including service-based discovery."
"I think some improvements to the Android app would be good."
"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."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"We would like the real-time monitoring of an interface to be improved within this solution."
"An update to the Android app would be appreciated."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
 

Pricing and Cost Advice

"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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 XI is an expensive solution."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
