Disable HikariPool logging

Question

This is perhaps a very simple question. How do i disable Hikari-CP debug logs? In my log file i have lots of these messages

DEBUG [.zaxxer.hikari.pool.HikariPool         


        

Answer 1

I use log4j properties, simple add these two lines:

log4j.category.com.zaxxer.hikari=INFO
log4j.logger.HikariPool=INFO

Answer 2

The class name is displaying in you DEBUG info: DEBUG [.zaxxer.hikari.pool.HikariPool:] - ... here the class name is zaxxer.hikari.pool.HikariPool, Just modify config file as being disaplayed.

I use logback logger, there is a file named logback.xml located in resources folder, to disable HikariPool logging, i write following config:

 <configuration>
...
    <logger name="com.zaxxer.hikari.pool.PoolBase" level="ERROR"/>
    <logger name="com.zaxxer.hikari.pool.HikariPool" level="ERROR"/>
    <logger name="com.zaxxer.hikari.HikariDataSource" level="ERROR"/>
</configuration>

Answer 3

The logger name should be com.zaxxer.hikari not org.zaxxer.hikari.

Answer 4

You can set the levels of Hikari loggers dynamically:

import org.apache.log4j.Logger;
import org.apache.log4j.Level;

public class App{
     public static main(String[] args) {
         Logger.getLogger("com.zaxxer.hikari.pool.PoolBase").setLevel(Level.OFF);
         Logger.getLogger("com.zaxxer.hikari.pool.HikariPool").setLevel(Level.OFF);
         Logger.getLogger("com.zaxxer.hikari.HikariDataSource").setLevel(Level.OFF);
         Logger.getLogger("com.zaxxer.hikari.HikariConfig").setLevel(Level.OFF);
         Logger.getLogger("com.zaxxer.hikari.util.DriverDataSource").setLevel(Level.OFF);
     }
}

I have tested this on hikariCP 3.4.1 with log4j 1.2.17
