Telemetry and Monitoring

Overview

Collecting and analyzing telemetry from infrastructure and applications so you can measure performance, availability, and health — the observation half of continuous feedback.

Units

  • Instrument applications and infrastructure for telemetry
  • Azure Monitor metrics, logs, and activity log
  • Application Insights application telemetry & dependencies
  • Querying telemetry (KQL) and building workbooks/dashboards

Concepts introduced

  • telemetry — metrics, logs, traces, and usage signals.
  • Azure Monitor — unified platform for infrastructure telemetry (metrics, logs, activity).
  • Application Insights — application/code-level telemetry (requests, dependencies, exceptions, traces).
  • Log Analytics — the KQL-queryable store behind logs and App Insights.
  • Alerts — turning stored telemetry into proactive notifications.

Key terms & commands

  • Three Azure Monitor sinks: Metrics, Activity Log, Log Analytics.
  • Instrument the app with the App Insights SDK to collect request/dependency/exception telemetry.
  • Query telemetry with KQL into workbooks and dashboards.

Hands-on

  • Add Application Insights to an app and view request/failure telemetry.
  • Query App Insights data with KQL and build a workbook.

Exam focus

  • Differentiate infrastructure (Azure Monitor) vs application (App Insights) telemetry.
  • Know App Insights data lives in a Log Analytics workspace and is KQL-queryable.
