* improve code for opentelemetry and add system metrics
* feat: add TraceLayer for HTTP service and improve metrics
- Add TraceLayer to HTTP server for request tracing
- Implement system metrics for process monitoring
- Optimize init_telemetry method for better resource management
- Add graceful shutdown handling for telemetry components
- Fix GracefulShutdown ownership issues with Arc wrapper
* improve code for init_process_observer
* remove tomlfmt.toml
* Translation comment
* improve code for console CompressionLayer params
- Rename package from rustfs-event-notifier to event-notifier for consistency
- Add shutdown hooks for event notification system in main process
- Handle graceful termination of notification services on server shutdown
- Implement initialization and configuration loading for event notification
- Fix environment variable configuration to properly parse adapter arrays
- Update example code to demonstrate proper configuration usage
This change ensures proper integration between rustfs and the event
notification system, with clean startup and shutdown sequences to prevent
resource leaks during application lifecycle.
Improve observability setup with the following changes:
- Replace static OnceCell with tokio::sync::OnceCell for guard management
- Add logger_level to OtelConfig for configurable tracing verbosity
- Improve telemetry initialization with better error handling
- Enhance logging filters and span configuration
Breaking Changes:
- Configuration now requires logger_level field
- Global guard management uses async-safe primitives
Example config:
observability:
endpoint: "http://localhost:4317"
logger_level: "debug" # New required field
- Add obs_config parameter to config struct with default path
- Document how to modify use_stdout value in README.md
- Support configuring observability via file or environment variables
This change helps users configure telemetry output destination for better
observability options in different deployment scenarios.
- Add initialization logic for the `rustfs-logging` crate.
- Provide examples for logging utilities.
- Include tests for logging and telemetry functionalities.
- Ensure proper configuration of dependencies in `Cargo.toml`.
