robintra/perf-sentinel v0.3.1 on GitHub

What's new in v0.3.1

Highlights

Score interpretation bands: IIS and waste ratio now carry human-readable labels (healthy / moderate / high / critical) in CLI output and JSON reports
Tempo trace ingestion: new perf-sentinel tempo subcommand to pull traces from Grafana Tempo for post-hoc analysis
Calibrate mode: new perf-sentinel calibrate to tune energy coefficients from real RAPL measurements
Electricity Maps API: real-time carbon intensity via opt-in API integration
30+ hourly carbon profiles: seasonal x hourly profiles for 30+ cloud regions (AWS, GCP, Azure)
Per-operation energy coefficients: SQL verb and HTTP payload size weighting for more accurate carbon estimates
Network transport energy: opt-in cross-region network energy term (Mytton et al. 2024)
3 new detectors: chatty service, connection pool saturation, serialized-but-parallelizable calls
Finding confidence field: ci_batch / daemon_staging / daemon_production for perf-lint IDE integration
Cloud SPECpower energy: opt-in CPU% + SPECpower interpolation for AWS/GCP/Azure VMs
Scaphandre RAPL integration: opt-in per-process energy measurement via Prometheus scraping
TLS for daemon OTLP receivers: optional TLS on gRPC (4317) and HTTP (4318) via tls_cert_path / tls_key_path
Sharded daemon deployment: validated horizontal scaling via OTel Collector loadbalancingexporter with correctness test and docker-compose example
Slow duration histogram: new perf_sentinel_slow_duration_seconds{type} Prometheus histogram for accurate global percentiles across sharded instances

Breaking changes

None. All changes are additive. Default behavior is unchanged.
