When troubleshooting gets messy

Introducing application map

What is application map?

• Built-in feature of application insights.
• Provides real-time visual map of application architecture.
• Automatically discovers components and external dependencies including:
  • Web apps
  • APIs
  • Databases
  • External dependencies
• Uses distributed tracing and runtime telemetry.
• Requires no manual configuration and enables faster troubleshooting

How application map is created

 

• Built using distributed tracing.
• Telemetry follows each request as it moves through your system.
• Traces are stitched together automatically to form a dependency graph

Key metrics

 

• Critical measures displayed including:
  • Latency
  • Request count
  • Failure rate
• No query required.

Application map in microservices

 

• Understanding complex architectures.
• Visualizes request flow.
• Identify cascading failures.
• Makes blast radius of an issue visible.
• Supports faster root-cause analysis.
