AI Summary

This release introduces a comprehensive OTEL metrics pipeline for task workers, enabling deep observability into worker performance. Workers can now collect process CPU/memory metrics, Node.js runtime metrics including event loop utilization and delay, and heap usage, all exportable to ClickHouse.

Key Highlights

  • OTEL metrics pipeline for task workers
  • Process CPU/memory metrics collection
  • Node.js runtime metrics (event loop utilization, event loop delay, heap usage)
  • User-defined custom metrics via otel.metrics.getMeter()
  • ClickHouse export with 10-second aggregation buckets and 1m/5m rollups
  • Dashboard query engine with typed attribute columns, prettyFormat(), and AI query support

New Features

  • OTEL metrics pipeline for task workers
  • Process CPU/memory monitoring
  • Node.js runtime metrics (event loop utilization, event loop delay, heap usage)
  • Custom metrics via otel.metrics.getMeter()
  • ClickHouse metrics export with aggregation buckets
  • Dashboard query engine with typed columns and AI query support

Full Release Notes

### Patch Changes

-   Add OTEL metrics pipeline for task workers. Workers collect process CPU/memory, Node.js runtime metrics (event loop utilization, event loop delay, heap usage), and user-defined custom metrics via `otel.metrics.getMeter()`. Metrics are exported to ClickHouse with 10-second aggregation buckets and 1m/5m rollups, and are queryable through the dashboard query engine with typed attribute columns, `prettyFormat()` for human-readable values, and AI query support.
