0.2.0

Added

• Selective Field Recording
  Introduced a new environment variable STATS_FIELDS for controlling which stats fields are collected and stored.

  • Empty (default) → collects all fields
  • ESSENTIAL → collects a minimal, core set of CPU, memory, and network fields
  • Comma-separated list → collects only those specified fields (e.g. cpu_percent,mem_used,pids_current)
    Log messages now alert if any requested fields do not exist in the actual Docker stats payload.

• Expanded Metrics Extraction

  • Additional fields extracted from Docker stats (e.g. block I/O, PID stats, per-CPU usage, and timestamps).
  • Enhanced memory stats (RSS, page faults, inactive pages, etc.).
  • Support for capturing read_time and preread_time as UNIX timestamps.

Changed

• Documentation

  • Updated README.md to include examples and instructions for using the new STATS_FIELDS feature.
  • Added more detailed “Available Metrics” tables in docs/configuration.md for quick reference.

• Internal Refactoring

  • Consolidated logic for filtering fields into a single, easily maintainable function.
  • Enhanced logging around missing or undefined fields.

Fixed

• Resolved minor logging inconsistencies for Docker events and container restarts.
