Angle-grinder (agrind) is a Rust command-line tool for parsing, filtering, and aggregating log data with a live-updating terminal UI. It provides a small query language with parsers (JSON, logfmt, split) and aggregators (sum, average, percentile, count, sort) for analytics on log streams without a full observability platform.

Use cases

• parse and aggregate JSON logs from the command line
• compute percentiles and averages over log streams
• live-updating terminal analytics on log files
• query structured logs without kibana or splunk
• count distinct values in log data
• filter and group log lines by fields

When to choose

• you need fast log analytics (millions of rows/sec) directly in the terminal
• your logs aren't in a centralized system like splunk or honeycomb
• you want a lightweight query language for parsing and aggregating logs

When to avoid

• you need long-term storage, dashboards, or alerting for logs
• you already have a full observability platform like kibana or sumologic
• you need a GUI-based log exploration tool
