Nagios Core and SolarWinds AppOptics are two contrasting monitoring solutions in the IT monitoring and management category. Nagios Core holds the upper hand for users who value flexibility, customization options, and cost-effectiveness, especially within technical environments. SolarWinds AppOptics is favored by those who prioritize ease of use, integration capabilities, and extensive feature sets.

Monitoring solution provides comprehensive visibility across IT infrastructure

The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Unique features allow consolidating and combing metrics into a single dashboard, but don't monitor mobile solutions

I would like to see more granular information provided on Unix applications. Also, the integration with Unix services should be a bit more straightforward in terms having an agent to retrieve your credentials rather than having to enter or save them for SSH on SolarWinds. From the outset, we had to set some commands to log into the search console, and they are saved on the solution, which presents a challenge in terms of exposure. The solution is unable to monitor APK solutions completely because we'd then be forced to break down the APK and provide the APIs or go through the source code. They don't have a module that can analyze an application that is maybe under-used.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."

"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."

"Provides timely notifications."

"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."

"The good thing about Nagios Core is it covers everything."

"We use the product to monitor server applications."

"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."

More Nagios Core pros

"The sum solution, NTA, and DPA."

"With minimal effort on our part, TraceView provides extraordinary visibility into the requests that flow through our SOA applications."

"Customer service is exceptional, as they are very much in tune with our service needs and are always in contact for both enhancement requests and overall satisfaction."

"Technical support is always live and they're supportive."

"I have found the most valuable feature is application performance management."

"The reporting of the solution is very good."

"Some of the most valuable features of SolarWinds are the topology discovery and network performance analysis."

"SolarWinds AppOptics does far more than what an individual may realize; it is not just a SIEM tool."

More SolarWinds AppOptics pros

Cons

"Nagios' great customizability is also one of its greatest drawback."

"It is a bit slow due to latency."

"The user interface could be more interactive because it is pretty basic."

"We're using the free version, which limits us in terms of the things that we can do."

"The dashboard should be improved."

"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."

"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."

"Default interface is clunky and slow."

More Nagios Core cons

"Because of its inability to monitor mobile solutions, I would rate this solution as a seven out of ten."

"The solution should be more user-friendly."

"The implementation needs improvement. It needs to get modernized with the newer cloud scenario in both public and private deployment models."

"We had a stability issue with a portion of the installation (Sequencer) when it was first introduced and have chosen not to install that specific function."

"I would like to see more integration with other tools that are available on the market."

"In terms of the technology, I think they need to put some more advanced troubleshooting into SolarWinds, in terms of AI capabilities. That's the next generation, especially in the cases of APIs which have already adopted AI capabilities into their products."

"I'd like to see the ability to use other internal instrumented applications as filters in the overview/aggregation screen."

"AppOptics would benefit from having a much more centralized view."

More SolarWinds AppOptics cons

Pricing and Cost Advice

"I would rate the solution's pricing an eight out of ten."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"Most the plugin features are free."

"Nagios Core is an open source solution, and there are no licensing fees."

"Nagios Core is free to use."

"Lessening the price point would be an improvement."

"We are using the open-source, unpaid version."

"The solution is expensive."

More Nagios Core pricing and cost advice

"Since it's a negotiable rate, I would rate the pricing as a five out of five."

"Mostly, it's a perpetual license. We don't have any customers using the subscription right now—it's mostly a perpetual license that the customers purchase. The licensing is based on the number of elements, whereas other solutions are node-based."

"I believe the current licensing cost is reasonable."
