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.

Monitoring over a thousand systems has improved decision making and operational visibility
From an advantage perspective, SolarWinds Server and Application Monitor is comparatively cheaper from a commercial point of view. It is easy to install and configure, very user-friendly, and quick to get up and running, allowing you to see the early value adds in your organization. It is compatible with most technologies for monitoring with very few chances of incompatibility. Configuration also allows us to monitor all the technical parameters we are looking for, making it a very good experience for us. The alerting feature in SolarWinds Server and Application Monitor is a main advantage, as it alerts based on threshold breaches and can raise tickets to the ticketing system, send SMS, and email notifications, allowing engineers to work on those tickets to resolve issues and avoid further impact. The visibility into server health is a beneficial feature that I am utilizing. We widely use various application performance metrics in SolarWinds Server and Application Monitor such as database monitoring and server monitoring, which are quite good enough for any monitoring solution. We utilize the customizable dashboards in SolarWinds Server and Application Monitor.

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."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"I can monitor a phone on a desk to very big servers of any company."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"The solution's most valuable feature is its simplicity."
"It is an open-source platform with valuable features for performance and stability."
"Features like monitoring and infrastructure dependency mapping are valuable to us."
"SolarWinds SAM has provided us with dynamic thresholds based on historical trends and requirements. The threshold gets configured automatically, so it's no longer necessary to configure it manually every time."
"Management Console - Managing service to each server enrolled in the Solarwinds is much easier. Using a web base console, you can control your service much convenient way. There is no need to login remotely. It save a lot of time and effort."
"The features like trends, capacity planning, recommendations, and diagnostics are the main items I focus on for added value."
"The most valuable feature of SolarWinds Server and Application Monitor is the network devices' performance monitor is the best."
"The initial setup was relatively easy, and we didn't have to install anything. All we had to do was put on the devices we wanted to monitor."
"SolarWinds SAM has significantly improved our workflow by allowing us to develop a comprehensive knowledge base of known errors and automate responses to specific alerts."
"We use the solution as a central monitoring tool. We use it to monitor every transaction that has a relation to the organization’s infrastructure."
 

Cons

"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"The product does not have SAP monitoring."
"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."
"I would like to see support for notification via SMS."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"Open-source software is usually not user-friendly."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"An additional feature that would improve this solution is the ability to complete root cause analysis."
"The templates could use improvement. Currently, they are quite complex. They should have drag-and-drop functionality instead. It would make it easier to use."
"The technical support team's response time could be improved."
"The tool's AppStack needs to improve in the storage monitoring part. It should also include an analytics and recommendation approach. If I have found a fault in a server or application, I would like to know what caused it and how do I recover from it."
"SolarWinds Server and Application Monitor could improve by having a cloud version. They have an observability platform but it still needs to be maintained by us."
"Nodes in Azure are able to be monitored with the use of agents, but this does not apply to cloud service offerings that are not node based."
"It lacks a user experience for measuring things like the end-to-end time for which a user waits for a specific response in the system. In the application layer, it has some very basic stuff. You have to build your own with manuscripts and things like that."
"They are complex to operate; users need to know what they want during setup."
 

Pricing and Cost Advice

"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"The pricing is high with separate licensing for the product and support."
"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."
"As it is not an agentless tool, I think it is expensive."
"Licensing costs are reasonable."
"Nagios XI, WhatsUpGold, Uptime Software, PRTG, Manage Engine, and SpiceWorks are the other tools that have lower pricing and licensing costs. However, they can't compete with SolarWinds when it comes to the features and functionality that SolarWinds can provide."
"SAM is not per server so the pricing model can be deceiving. If you have an enterprise environment, you will quickly exceed your licensing quickly. You should know this before going in."
"The solution is overpriced in terms of application management."
"I have always said SolarWinds is very “proud” of their products, meaning they are expensive. I cannot afford to purchase all the licenses I need for all the SolarWinds products."
"Its licensing is on a yearly basis. It is just the standard price, but it can vary depending on the current rate of the dollar."
"I would rate the pricing for this solution a three out of five."
"The product might cost you $30,000 USD to buy, but scaling this solution requires the purchase of additional polling engines at $20,000 USD each."
"Pricing is inexpensive, starting at 2440 euros. For that, you get the ability to monitor a couple of nodes and one year of maintenance and support."
