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

"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"The solution is pretty stable."
"The alerting system is very effective."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"It is an open-source platform with valuable features for performance and stability."
"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."
"The most valuable feature of SolarWinds Server and Application Monitor is its powerful monitoring capabilities."
"The application dependency feature identifies issues between applications and servers or within the network where the application is hosted. It highlights related problems, whether related to packet processing or other issues, enabling the creation of alerts and reports accordingly."
"The solution can be deployed quickly."
"The features like trends, capacity planning, recommendations, and diagnostics are the main items I focus on for added value."
"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."
"Manage Groups: The capability to group appropriate devices gives better visibility of sites, categories, or critical regions. The same can be used to represent a dashboard for higher management."
"I find it to be a strong product suite, particularly when you need a comprehensive monitoring tool."
 

Cons

"Open-source software is usually not user-friendly."
"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."
"The reporting structure could be more streamlined."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"I would like to see support for notification via SMS."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"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 see support for non-Windows or non-Microsoft domains, especially Apache and other non-Windows servers."
"It should also be easier to upgrade SolarWinds. AppDynamics is harder to deploy but easier to upgrade. So AppDynamics takes a lot of time and effort to install, but you can upgrade it in minutes. SolarWinds is the opposite. It's easy to deploy, but upgrades take forever. To date, nobody can complete it on time, so the production environment is sitting idle."
"The technical support team's response time could be improved."
"A lot of times, we have to do a lot of manual cleanups."
"It needs time-based functions for monitoring. Some things need to be polled on a specific schedule or only during a specific window."
"SAM's software-defined network monitoring capability is also low and could be improved."
"SolarWinds Server and Application Monitor could improve the server monitoring and the web application monitoring features are not good. Microsoft SCOM has better server monitoring."
"The tool’s report feature created issues for us. We needed to gain skills to use that feature. The tool’s customization is not easy since you have to reconfigure the whole system."
 

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."
"We are using the free version of this solution."
"Nagios XI is open source."
"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 pricing is high with separate licensing for the product and support."
"Nagios XI is an expensive solution."
"Licensing costs are reasonable."
"The price is too high."
"I would rate the pricing for this solution a three out of five."
"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."
"The licenses start from USD 3000.00 and go up to USD 20,000.00 for the year. It's a perpetual license. Nothing is free in SolarWinds, anything that you need is an additional cost."
"The solution's price is reasonable. Though it's on the higher side, the tool is worth the money."
"When planning for the number of licenses to purchase, make sure you understand all of the elements within an application required to really understand performance well. In our case, we quickly came to the conclusion that an unlimited license for SAM was the way to go."
"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 think SolarWinds' pricing is very decent compared to other competitors in the market."
