LogBlast

LogBlast is a command‑line tool that parses large log files in a streaming fashion, keeping memory usage low while delivering results in seconds. It automatically detects common log formats such as Nginx and Apache combined logs, and then provides filtered views based on level, time range, regex, IP address, or HTTP status. Users can combine multiple filters and invert them without writing custom scripts.

The utility presents per‑level statistics with visual bars, lists top IPs, paths, and user agents, and highlights anomalies like error spikes or IP bursts using configurable thresholds. Output can be rendered as color‑coded tables in the terminal or exported to CSV or NDJSON for downstream processing. A simple YAML file in the working directory stores reusable filter sets and anomaly settings, which are loaded automatically.

Designed for developers and DevOps engineers who need rapid insight from multi‑gigabyte logs, LogBlast runs on any platform supported by Rust, streams data through a BufReader pipeline, and integrates smoothly with standard UNIX pipelines via stdin support.
