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."
"The product allows comprehensive monitoring of your environment, from basic monitoring of your servers health to more complex tasks like AD, database, and, to some extent, application-level monitoring."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"The solution's most valuable feature is its simplicity."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."
"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."
"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 is an open-source platform with valuable features for performance and stability."
"We are consultants and thanks to Pandora can detect a lot of disasters that other companies can't, and we can offer high availability of the system to the client."
"The most valuable feature is that it is an all-in-one monitoring system."
"What I value most about Pandora FMS is the simplicity of working with it."
"In comparison with most monitoring software, this software is incredibly easy to use."
"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."
"We are able to control our business with this all-in-one monitoring tool."
"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."
"Network monitoring is fun again with Pandora FMS."
 

Cons

"Nagios XI can improve its GUI for users with a new look."
"The reporting structure could be more streamlined."
"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."
"The interface could be more user-friendly."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"The installation can get very difficult depending on what Linux flavour you are using."
"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."
"An update to the Android app would be appreciated."
"We would like the real-time monitoring of an interface to be improved within this solution."
"This solution requires proper training to get 100% out of it."
"It would be helpful to include the generation of reports for times that the network was out of service."
"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."
"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."
 

Pricing and Cost Advice

"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"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."
"As it is not an agentless tool, I think it is expensive."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Licensing costs are reasonable."
"Nagios XI is open source."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
