Executive SummaryUpdated on Oct 9, 2024

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.

Features: Nagios Core provides flexibility with extensive customizability and a vast plugin ecosystem, as well as robust monitoring and alerting features. SolarWinds AppOptics offers application performance management, topology discovery, and real-time reporting on a more user-friendly platform.

Room for Improvement: Nagios Core faces challenges with complex setups, a steep learning curve, and limited reporting capabilities without customization. SolarWinds AppOptics could enhance cloud integration, consolidate its application stack, and better tailor its licensing model.

Ease of Deployment and Customer Service: Nagios Core, mainly used in on-premises deployments, relies on community guidance due to its open-source nature and lacks official support. SolarWinds AppOptics provides flexible deployment options with vendor support, suitable for users seeking direct assistance.

Pricing and ROI: Nagios Core's open-source model allows cost savings, with users investing mostly in setup and maintenance. SolarWinds AppOptics involves licensing fees based on elements, and many users find the investment justified by the comprehensive features and support for larger environments.

Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

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.
