redis-faina

===========

A query analyzer that parses Redis' MONITOR command for counter/timing stats about query patterns

At its core, redis-faina uses the Redis MONITOR command, which echoes every single command (with arguments) sent to a Redis instance. It parses these

entries, and aggregates stats on the most commonly-hit keys, the queries that took up the most amount of time, and the most common key prefixes

as well.

Usage is simple:

    # reading from stdin

    redis-cli -p 6490 MONITOR | head -n <NUMBER OF LINES TO ANALYZE> | ./redis-faina.py [options]

    # reading a file

    redis-cli -p 6490 MONITOR | head -n <...> > /tmp/outfile.txt  ./redis-faina.py [options] /tmp/outfile.txt

    

options:

     --prefix-delimiter=...          String to split on for delimiting prefix and rest of key, if not provided `:` is the default . --prefix-delimiter=#

      --redis-version=...                               Version of the redis server being monitored, if not provided `2.6` is the default. e.g. --redis-version=2.4

The output (anonymized below with 'zzz's) looks as follows:
