Introduction

This tool reads sql-converted mysql binlog files and inserts selected data form insert statements into InfluxDB.

Usage examples:

for f in DBSRV-bin.00*.gz; do
echo $f ; time zcat $f | mysqlbinlog - | mysqlinflux ;
done

or

parallel 'echo {} ; zcat {} | mysqlbinlog - | mysqlinflux' ::: DBSRV-bin.00*.gz

Configuration

A file 'conf.json' must be in folder of the binary
