Built LogSlash — a Rust pre-ingestion log firewall to reduce observability costs

Built LogSlash, a Rust-based log filtering proxy designed to suppress duplicate noise before logs reach observability platforms.

Goal: Reduce log ingestion volume and observability costs without losing critical signals.

Key features:

• Normalize → fingerprint logs
• Sliding-window deduplication
• ERROR/WARN always preserved
• Prometheus metrics endpoint
• Docker support

Would appreciate feedback from DevOps / infra engineers.
