azure__monitor with command monitor_logs_query - Query logs with KQL

Application Insights

azure__applicationinsights with command applicationinsights_component_list - List App Insights resources

Log Analytics

azure__kusto with command kusto_cluster_list - List clusters
azure__kusto with command kusto_query - Execute KQL queries

If Azure MCP is not enabled: Run /azure:setup or enable via /mcp.

CLI Reference

# List Log Analytics workspaces
az monitor log-analytics workspace list --output table

# Query logs with KQL
az monitor log-analytics query \
  --workspace WORKSPACE_ID \
  --analytics-query "AzureActivity | take 10"

# List Application Insights
az monitor app-insights component list --output table

# List alerts
az monitor alert list --output table

# Query metrics
az monitor metrics list \

  --metric "Percentage CPU"

Common KQL Queries

// Recent errors
AppExceptions
| where TimeGenerated > ago(1h)
| project TimeGenerated, Message, StackTrace
| order by TimeGenerated desc

// Request performance
AppRequests
| where TimeGenerated > ago(1h)
| summarize avg(DurationMs), count() by Name
| order by avg_DurationMs desc

// Resource usage
AzureMetrics
| where TimeGenerated > ago(1h)
| where MetricName == "Percentage CPU"
| summarize avg(Average) by Resource

Monitoring Strategy

What to Monitor	Service	Metric/Log
Application errors	App Insights	Exceptions, failed requests
Performance	App Insights	Response time, dependencies
Infrastructure	Azure Monitor	CPU, memory, disk
Security	Log Analytics	Sign-ins, audit logs
Costs	Cost Management	Budget alerts
