Overview

Package redis package contains prospector and harvester to read the redis slow log

The redis slow log is stored in memory. The slow log can be activate on the redis command line as following:

CONFIG SET slowlog-log-slower-than 2000000

This sets the value of the slow log to 2000000 micro seconds (2s). All queries taking longer will be reported.

As the slow log is in memory, it can be configured how many items it consists:

CONFIG SET slowlog-max-len 200

This sets the size of the slow log to 200 entries. In case the slow log is full, older entries are dropped.
