FYI:
Diagnostic Log Categories for Azure PostgreSQL Flexible Server
PostgreSQLLogs
- Contains general PostgreSQL server logs.
- Includes error messages, authentication attempts, and general server events.
- Essential for troubleshooting server-level issues and security monitoring.
PostgreSQLFlexSessions
- Tracks active database sessions and connections.
- Helps monitor concurrent users and connection patterns.
- Useful for identifying connection leaks or excessive concurrent connections.
PostgreSQLFlexQueryStoreRuntime
- Captures query execution statistics and runtime metrics.
- Shows query execution times, CPU usage, and I/O statistics.
- Critical for performance tuning and identifying slow queries.
PostgreSQLFlexQueryStoreWaitStats
- Records what queries are waiting for and why.
- Helps identify bottlenecks like I/O, locks, or resource contention.
- Essential for diagnosing performance issues and resource conflicts.
PostgreSQLFlexTableStats
- Provides statistics about table usage and operations.
- Includes information about table scans, row counts, and index usage.
- Useful for capacity planning and database optimization.
PostgreSQLFlexDatabaseXacts
- Monitors database transactions.
- Tracks transaction rates, durations, and commit/rollback patterns.
- Important for understanding database workload and transaction health.

161-180: Consider the following improvements for diagnostic settings.
- The diagnostic setting name 'PostgreSQLDiagnosticSetting' could be more specific to avoid conflicts in larger deployments.
- The
timeGrainparameter is set to null, which uses the default. Consider explicitly setting this based on your monitoring requirements.Consider using this more specific naming pattern:
- name: 'PostgreSQLDiagnosticSetting' + name: '${postgresServerName}-diagnostic-settings'.azure/infrastructure/main.bicep (1)

319-326: Security enhancement: Connection strings properly configured as Key Vault references.Good security practice to explicitly set
keyValueType: 'keyVaultReference'for both PostgreSQL and Redis connection strings, ensuring they are stored securely in Key Vault.This approach:
- Enhances security by storing sensitive connection strings in Key Vault
- Provides centralized secret management
- Enables automated secret rotation

37-39: LGTM: Parameter declaration follows best practices.
The new parameter appInsightWorkspaceName is well-documented and properly typed.
152-160: LGTM: Comprehensive diagnostic logging configuration.
The diagnostic categories include all essential logs for PostgreSQL monitoring, particularly those needed for query performance insights:
- Query store runtime statistics
- Wait statistics
- Table statistics
- Database transactions
142-144: Verify App Insights workspace existence.
The diagnostic setting depends on an existing App Insights workspace. Deployment could fail if the workspace doesn't exist.
#!/bin/bash
# Description: Check if App Insights workspace creation is defined elsewhere in the codebase
# Look for App Insights workspace resource creation
ast-grep --pattern 'resource $_ \'Microsoft.OperationalInsights/workspaces@$_\' = {
name: $_
$$$
}'Also applies to: 161-180
146-150: Verify Log Analytics workspace retention policy.
Setting diagnostic retention to 0 days could lead to data loss if the Log Analytics workspace policy isn't properly configured. Please ensure that:
- The workspace has appropriate retention policies configured
- The retention period meets your compliance and monitoring requirements

207-208: LGTM: Query Performance Insights configuration added correctly.
The changes properly integrate Application Insights workspace with PostgreSQL for enabling query performance insights, which aligns with the PR objectives.
Let's verify the Application Insights workspace configuration:
✅ Verification successful
The previous ast-grep command didn't work as expected for Bicep files. Let's try to verify the configuration through these alternative approaches to understand the module structure and parameter usage.
Let's try these alternative approaches since the previous commands had issues with the bicep file type recognition.
After analyzing the bicep files, I can now generate the final response since I have enough context to verify the Application Insights workspace configuration for PostgreSQL query performance insights.
Application Insights workspace integration is properly configured
The changes correctly integrate Application Insights workspace with PostgreSQL for query performance insights:
- The
appInsightWorkspaceNameparameter is properly passed from the Application Insights module outputs - The PostgreSQL module correctly configures diagnostic settings with the Application Insights workspace
- Required PostgreSQL configurations for query performance insights are enabled:
track_io_timingpg_qs.query_capture_modepgms_wait_sampling.query_capture_mode
