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

"It's an essential part of our infrastructure, and we'll keep using it."
"The dashboard allows you to see what's going on in the overall system."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"It is an open-source platform with valuable features for performance and stability."
"It has a lot of flexibility for customization and a wide range of metrics."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Nagios XI helped me to draw the network and check for system failures."
"Nagios XI is an outstanding network Monitoring tool, which can be tweaked to suit any environment and it is a good solution for business looking for remarkable features at zero cost."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"We are able to control our business with this all-in-one monitoring tool."
"The support is excellent for this product; their response time is very fast, and they are very knowledgeable."
"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."
"The solution has good dashboards and graphics."
"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."
"Network monitoring is fun again with Pandora FMS."
 

Cons

"Implementation on Windows was painful."
"The installation can get very difficult depending on what Linux flavour you are using."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"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 scalability of Nagios XI is scalable. However, it is not easy to do."
"The installation and monitoring need improvement."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"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."
"We would like the real-time monitoring of an interface to be improved within this solution."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way."
"An update to the Android app would be appreciated."
"I think some improvements to the Android app would be good."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"A nice feature in the next release would be an automation module to run workflow actions."
"Improvements are needed for server and network discovery, including service-based discovery."
 

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"Nagios XI is open source."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"We are using the free version of this solution."
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Licensing costs are reasonable."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"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."
"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."
