Gartner's Definition

Application Performance Monitoring (APM) is a suite of monitoring software comprising digital experience monitoring (DEM), application discovery, tracing and diagnostics, and purpose-built artificial intelligence for IT operations. APM strives to detect and diagnose complex application performance problems to maintain an expected level of service by tracking key software application performance metrics using monitoring software and telemetry data.

APM and observability tools provide visibility into the digital experience that optimizes user engagement. Use cases now include security, and OpenTelemetry portends a new type of standardization. With many tools available, I&O leaders must identify their critical capabilities.

Observation of an application's complete transactional behaviour
Automated discovery and mapping of an application and its infrastructure components (including cloud services)
Monitoring of applications running on mobile (native and browser) and desktop browsers
Identification and analysis of application performance problems and their impact on business outcomes
Native integration capabilities with automation and service management tools, as well as native integration with public cloud providers - e.g. AWS, Cloudwatch, Azure Monitoring and Google Cloud Operations
Analysis of business key performance indicators (KPIs) and user journeys - for example, login to check-out
The ability to perform interactive interrogation of multiple telemetry types (such as traces, metrics, and logs) to detect "unknown unknowns" – that is, the ability to identify underlying issues to unexpected events and gaps in telemetry coverage
Application security functionality delivered via a common agent or framework for APM

Endpoint monitoring to understand the user experience and its impact on business outcomes
Support for virtual desktop infrastructure (VDI) monitoring
Performance testing and integration with load testing tools

The Core Layer comprises the basic requirements of functional areas, such as profiling and DEM, that must be available in some form for the solution to be viable and complete
The Specialized Layer has functional areas that deliver specific value-added features, such as RASP or SLO-support, that are increasingly required by some organizations, and may serve to identify distinctive traits during product selection
The Differentiator Layer is aligned to the needs of organizations that manage complex and distributed environments and have embedded APM and observability solutions into the fabric of their development, deployment, and operations processes.

Gartner-mentioned limitations
- No ServiceNow integration
- Limited Cloud Visiblity
Current deployment
- Primarily alerts on system / service outages Some apps have other thresholds mentioned Contention Rate High GC Time Percentage High
  - No mention of "business transaction" performance
    - No mention of transactions at all
- Seems to be tied to app's .exe – how can this work for SaaS / PaaS?
- Has Sterling – but not OMFT!
- Has "ESB" but not OIC…
Cloud Platforms Supported
- Google, AWS, Azure, IBM
- … but not Oracle
Oracle aspects
- Supports Oracle for Cloud Monitoring
- No support for Oracle for Observability
  - But they do support Google, AWS, Azure, IBM for this
- OIC ?
- OCI ?
Third party SaaS
SalesForce apps
Instrumentation options?
- Maximo is Java-based: is it eligible?
