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

"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."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"This solution has improved our ability to determine the source of a connection failure in our network, and now we are able to monitor the service provider's router and make that determination."
"The most valuable feature is the monitoring of processes."
"This is a very good solution and it is simple to use, for any company."
"Nagios XI is stable."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"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 support is excellent for this product; their response time is very fast, and they are very knowledgeable."
"Network monitoring is fun again with Pandora FMS."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"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."
"Thanks to this software and to the work of the support team, we have everything under control."
"What I value most about Pandora FMS is the simplicity of working with it."
 

Cons

"The GUI could be improved."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"There's no convenient way to manage notes as the only way is to manage them through the database."
"The installation can get very difficult depending on what Linux flavour you are using."
"We're still experiencing stability issues with regards to collecting performance graphs."
"The product does not have SAP monitoring."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"I think some improvements to the Android app would be good."
"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."
"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."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"This solution requires proper training to get 100% out of it."
"The price for Pandora FMS is expensive."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"We would like to see improvement in the mainframe integration that this solution is capable of."
 

Pricing and Cost Advice

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"We are using the free version of this solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
