Monolog version 1.25.3

Hi,

I am using monolog in Drupal. I am finding a way to print info & warn log to stdout, and print error log to stderr, if I configure 2 handlers, error log will appear in both stdout and stderr, that's not what I expected, error log should not print to stdout.

Here is what I configured.

services:
  # Monolog handlers.
  # https://github.com/Seldaek/monolog/blob/1.25.3/README.md
  monolog.handler.std_info:
    class: Monolog\Handler\StreamHandler
    arguments: ['php://stdout', '%monolog.level.info%']
  monolog.handler.std_error:
    class: Monolog\Handler\StreamHandler
    arguments: ['php://stderr', '%monolog.level.error%']

The StreamHandler only accept minimum logging level.

/**
 * @param string|int $level The minimum logging level at which this handler will be triggered
 */

Is it possible to set maxium logging level?

Thanks.

Finally I find a way.

Configure info handler behind error handler.
Set error handler $bubble as FALSE.

You can also use FilterHandler to only pass some exact levels into a given handler.

@Seldaek Thank you for the answer. I haven't noticed FilterHandler, it would help.
