poke

poke is summoned for analyzing MySQL slow query logs, poke examines log entries, converts text to JSON format and detects following features:

  • time when query was started (using Time: and Query_time fields),
  • query type: SELECT, INSERT, UPDATE, DELETE, DROP
  • query length

After analyzing slow logs poke will print JSON output to stdout, like as following:

What we can do with that JSON

We can use github.com/kovetskiy/jsql and query JSON dataset using SQL queries.
