⭐ HIGHLIGHTED | Observability Framework 👁️📊

  • Introduced a new observability framework utilizing the ipc-observability crate.
    • This framework introduces events and metrics for detailed system monitoring and analysis.
    • Integrates with Prometheus for real-time tracking, alerting, and visualization.
    • Simplifies observability integration with ready-to-use macros, structs, and functions.

IPC now emits events during execution. These events are recorded in the Journal, and are transformed into Prometheus metrics. Observability configuration is performed via config.toml.

Refer to full observability documentation here.
