Rabbit Topic embed log level into routing key

[charithf]

I'm interested in the rabbitmq log appender. Can I put the log level into the routing key? Is there a way to configure this? or else is there a way to access the log level via the payload?

what layout type: did you choose, it's configurable from the base log4js feature.
Just add it to the bottom of the rabbit {} list of config attributes:

    type: '@log4js-node/rabbitmq',
    protocol: 'amqps',
       .....  0,
    layout: { type: 'json', separator: ',' }
  }

I implemented "custom" json layout, which inherited the color and everything layout.
My rabbit logs have this:
"level":{"level":20000,"levelStr":"INFO","colour":"green"}

export interface BaseLayout { type: 'basic';
export interface ColoredLayout { type: 'colored' | 'coloured';

Pick a standard layout or customize you own.

function timestampLevelAndCategory(loggingEvent, colour) {
  return colorize(
    util.format(
      '[%s] [%s] %s - ',
      dateFormat.asString(loggingEvent.startTime),
      loggingEvent.level.toString(),
      loggingEvent.categoryName
    ),
    colour
  );
}
