## What it is
A Python command-line tool from Facebook that parses the output of Redis' MONITOR command and aggregates counter and timing statistics about query patterns. It reports top key prefixes, most-hit keys, common commands, and command timing percentiles.

## Use cases
- analyze which Redis keys are hit most often
- find slowest Redis commands from MONITOR output
- profile Redis query patterns and timing percentiles
- identify hot key prefixes on a busy Redis server
- measure commands per second on a Redis instance

## When to choose
- you need quick, dependency-light analysis of Redis MONITOR output
- you want per-command timing and top-key stats without installing agents
- you are debugging query patterns on a legacy Redis 2.x-era deployment

## When to avoid
- you need real-time or continuous monitoring with dashboards and alerting
- your Redis server has low request rates, making MONITOR-based timing inaccurate
- you need an actively maintained tool with support for modern Redis versions
