Study Azure AZ-900 Monitoring Tools: key concepts, common traps, and exam decision cues.

On this page

Monitoring questions on AZ-900 often become close-answer traps because the tool names all sound helpful. The real skill is deciding whether the need is recommendations, service-health awareness, broad monitoring, deeper log analysis, alerting, or application-level insight.

Keep these tools separate

Tool	Best mental label
Azure Advisor	recommendations
Azure Service Health	service-impact and health information
Azure Monitor	broad monitoring platform
Log Analytics	query and analyze collected log data
Azure Monitor alerts	trigger notifications from conditions
Application Insights	application performance and telemetry visibility

The monitoring chooser

If the stem is really about…	Strongest first reading
improvement recommendations	Azure Advisor
Azure platform incidents or planned maintenance	Azure Service Health
broad metrics, logs, and observability	Azure Monitor
querying collected log data	Log Analytics
notifying when a condition is met	Azure Monitor alerts
tracing application performance	Application Insights

Common traps

using Service Health when the stem is about your own resource telemetry
using Azure Monitor when the stem is really about platform incidents
forgetting that Application Insights is the app-observability lane inside the broader monitoring story

Decision order that usually wins

Decide whether the need is recommendations, platform-health awareness, broad monitoring, log analysis, alerts, or app telemetry.
Keep Service Health separate from resource telemetry and app telemetry.
Use Azure Monitor as the broad platform and observability lane.
Use Log Analytics when the question is really about querying collected logs.
Match the monitoring tool to the exact visibility requirement before adding alerts or exports.
