Dynamic profiling intel sync #78

ashokbytebytego · 2025-11-18T20:27:57Z

Add Dynamic Profiling Data Models and PostgreSQL Schemas

Summary

This PR contributes the foundational data model infrastructure for the dynamic profiling feature, including PostgreSQL database schemas and Python API models.

What's Included

Database Schema (`scripts/setup/postgres/`)

ProfilingRequests: Track start/stop profiling requests
ProfilingCommands: Store commands to be executed by agents
HostHeartbeats: Monitor agent health and status
ProfilingExecutions: Record profiling execution history
Supporting tables for namespace, service, container, and process mappings

API Models (`src/gprofiler/backend/models/`)

Pydantic models for request/response validation
Type-safe data structures for profiling operations
Support for host-level and process-level profiling

Documentation (`docs/`)

Comprehensive guide for dynamic profiling architecture
Database schema documentation with ERD
Setup and testing instructions

Tests (`src/tests/`)

Unit tests for profiling host status functionality
Test scripts for model validation

Benefits

✅ Clean separation of dynamic profiling data from existing metrics
✅ Support for both host-level and process-level profiling
✅ Extensible schema for future profiling capabilities
✅ Well-documented for easy onboarding

- Add PostgreSQL schemas for dynamic profiling tables - Add Python Pydantic models for API requests/responses - Add 4 REST API endpoints for dynamic profiling: * POST /api/metrics/profile_request * POST /api/metrics/heartbeat * POST /api/metrics/command_completion * GET /api/metrics/profiling/host_status - Add comprehensive documentation and setup guides - Add unit tests for profiling host status functionality - Includes Slack notification support for profiling events This contribution provides the complete dynamic profiling feature for Intel's gprofiler-performance-studio, enabling start/stop profiling commands, heartbeat monitoring, and host status tracking.

- Remove MetricsPublisher import from main.py - Remove startup/shutdown event handlers for MetricsPublisher - Remove all send_sli_metric() calls from profiles_routes.py These are Pinterest-specific metrics tracking not needed for Intel PR.

- Remove MetricsPublisher configuration from args.go - Remove metricsPublisher initialization from main.go - Remove all SendSLIMetric() calls from queue.go and worker.go - Remove related comments These are Pinterest-specific metrics tracking not needed for Intel PR.

The variable name TEST_TEST is unclear and appears to be a placeholder or typo. Consider renaming to something more descriptive like TEST_MODE or removing if unused.

The addition of S3ForcePathStyle: aws.Bool(true) changes S3 path handling behavior but lacks explanation. Add a comment explaining why path-style addressing is required (e.g., for LocalStack compatibility or S3-compatible services).

Suggested change

Endpoint: aws.String(args.AWSEndpoint),

Endpoint: aws.String(args.AWSEndpoint),

// Use path-style addressing for S3 to support custom endpoints (e.g., LocalStack, MinIO, or other S3-compatible services)

Debug logging statements should be removed before merging to production. These appear to be temporary debugging code added during development.

Multiple DEBUG logging statements should be removed or converted to proper debug level logging before production deployment.

Please check if commenting out "raise" and "return" statements is intentional.

Hi @mlim19 , The raise and return statements are not commented out - they are fully active and functional.
The confusion may be coming from how GitHub displays the diff. The removed MetricsPublisher code (between the comment and the raise statement) might make it appear compressed in the diff view.

- Removed metricsPublisher initialization and cleanup calls from main.go - This completes the cleanup of Pinterest-specific metrics code - Indexer now builds successfully in Docker

- Fixed multiple statements on same line (syntax errors from previous cleanup) - Split logger.error() and raise HTTPException() onto separate lines - Fixed indentation after except blocks - All services now build and run successfully

PR #78 - Required Fixes Before Approval

Date: December 16, 2024
PR: #78

The following issues must be resolved before this PR can be approved for merge:

DEPLOYMENT CONFIGURATION (deploy/.env)

ISSUE 1.a: AWS Configuration Hardcoded

Lines 7, 35-38: AWS_REGION, BUCKET_NAME, and SQS URLs are hardcoded
REQUIRED FIX: Keep these fields empty/configurable as they were in master branch
RATIONALE: S3 bucket names must be globally unique; regions vary by deployment

ISSUE 1.b: LocalStack Configuration in Production File

Lines 49-68: LocalStack and test metrics configuration
REQUIRED FIX: Remove lines 49-68 entirely OR move to separate .env.local file
These include:
- LocalStack endpoints (lines 53-55)
- Metrics configuration with test values (lines 57-67)
RATIONALE: LocalStack is dev-only; metrics should default to disabled

ISSUE 1.c: Metrics Configuration

If metrics feature is retained, METRICS_ENABLED must default to "false"
Provide documentation for metrics host setup if this feature is included
Remove test UUIDs and localhost endpoints

DOCKER COMPOSE SECURITY (deploy/docker-compose.yml)

ISSUE 2.a: PostgreSQL Port Exposed

Lines 58-59: Exposes database port 5432 to all network interfaces
REQUIRED FIX: Remove these lines or comment them out
RATIONALE: Containers communicate internally; external exposure is security risk

ISSUE 2.b: LocalStack as Production Dependency

Lines 96, 104, 119, 220, 233: LocalStack hardcoded in service configurations
Lines 242-266: LocalStack service definition
REQUIRED FIX:
- Remove LocalStack from main docker-compose.yml
- Create separate docker-compose.local.yml for development
- Remove LocalStack from service dependencies
RATIONALE: Production should use real AWS services, not emulator

DATABASE MIGRATION (scripts/setup/postgres/)

ISSUE 3.a: No Migration Strategy

dynamic_profiling_schema.sql adds 10+ new tables
No migration scripts for existing deployments
REQUIRED FIX:
- Provide upgrade script: migrations/add_dynamic_profiling.up.sql
- Provide rollback script: migrations/add_dynamic_profiling.down.sql
- Document migration process
RATIONALE: Existing production deployments need safe upgrade path

ACCEPTANCE CRITERIA

[ ] deploy/.env has no hardcoded AWS values
[ ] deploy/.env has no LocalStack configuration
[ ] deploy/docker-compose.yml has no exposed database ports
[ ] deploy/docker-compose.yml has no LocalStack dependencies
[ ] Migration scripts provided for schema changes

- Remove hardcoded AWS config and LocalStack from deploy/.env - Remove LocalStack service from deploy/docker-compose.yml - Remove exposed PostgreSQL port from docker-compose.yml - Add database migrations (up/down) for dynamic profiling

@ashokbytebytego and @prashantbytesyntax I successfully got the changes working in my local machine. It looks good so far but will evaluate with the changes in gprofiler agent side.
In the meantime, please address the outstanding CI build issues.
