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

"It's great for monitoring IT services infrastructure."
"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."
"Nagios XI is stable."
"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 useful aspect of this solution is the ability to customize it for the client agent."
"The installation is no problem. I've installed Nagios several times."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"The more valuable feature of this solution is the Exchange feature."
"If you are looking for a single pane of glass to monitor Windows products then SolarWinds is your product."
"I have found the visibility into server health with SolarWinds Server and Application Monitor very beneficial, which we use on a daily basis."
"SSL Certificate Monitoring and Expiry Alerting"
"The features like trends, capacity planning, recommendations, and diagnostics are the main items I focus on for added value."
"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."
"SolarWinds allows network administrators to easily monitor the network by customizing the pages to see what exactly is needed, in addition to the deep statistics shown for nodes and interfaces like response time, packet loss, interface CRC, interface errors, as well as the rich graphs for all network elements."
"SolarWinds SAM has provided us with dynamic thresholds based on historical trends and requirements, so the threshold gets configured automatically, and it's no longer necessary to configure it manually every time."
 

Cons

"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."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"The product does not have SAP monitoring."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"The tool's AI model needs to be fixed."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"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."
"PerfStack can be made more effective. I am sure SolarWinds already has a plan for the same in coming versions."
"The product does not explain why a problem occurred."
"Scalability was an issue in the past."
"Some custom applications cannot be monitored, and a lot more applications need to be included."
"SolarWinds' interface is slow, and this is a global concern."
"Having two places to build and manage alerts is not efficient and not all alerting tools are available in the trap manager."
"AppInsight needs to include more applications, the current list is very limited."
"For each poller, SolarWinds Server and Application Monitor can only monitor up to ten thousand components, which restricts scalability."
 

Pricing and Cost Advice

"As it is not an agentless tool, I think it is expensive."
"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Nagios XI is open source."
"The pricing is high with separate licensing for the product and support."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"I like the pricing for this SolarWinds product."
"We are on an annual license to use the solution. The price of the solution is expensive. The price is based on a bunch of factors, such as the number of engines and elements."
"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."
"When compared to other licensed models in the market, it stands out as one of the more cost-effective options."
"I would advise potential buyers to wait until the end of the quarter, end of year, or other time to place orders. There are actually great deals to be had at those times if your budget cycle can match up."
"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."
"I would rate the pricing for this solution a three out of five."
