yaol
Yet another observability library. Wires OpenTelemetry traces, metrics and logs plus structlog and Pyroscope profiling from a single config object.
Usage
from yaol import ObservabilityConfig, setup, shutdown, instrument_asyncpg
config = ObservabilityConfig(
service_name="bot",
service_version="0.1.7",
environment="prod",
otlp_endpoint="http://172.17.0.1:4317",
logger_levels={"sqlalchemy.engine": "WARNING"},
)
setup(config)
instrument_asyncpg()
...
shutdown()
from_env builds the same object from environment variables:
ENV, OTEL_EXPORTER_OTLP_ENDPOINT, LOG_LEVEL, YAOL_JSON_LOGS,
YAOL_EXPORT_LOGS, YAOL_EXPORT_METRICS, YAOL_METRIC_INTERVAL_MILLIS,
YAOL_PROFILING_ENABLED, PYROSCOPE_ADDRESS, PYROSCOPE_SAMPLE_RATE.
Signals
- Traces — OTLP gRPC,
BatchSpanProcessor. - Metrics — OTLP gRPC,
PeriodicExportingMetricReader. - Logs — OTLP gRPC alongside the stdout handler; both are attached to the root logger.
- Profiles — Pyroscope push, off by default.
shutdown() flushes every provider, which the previous ad-hoc setup did not do.
