The threshold property at appenderlevel wont work or did not exist yet

[tanujvishnoi]

I am looking for flushing different Appenders logs as per level . In the log4j there was originally a concept of threshold , which actually helps to difne a log level limit at appender level, here the same is not working

    appenders: {
        console: {
            type: 'console', layout: {
                type: 'pattern',
                pattern: '[%p] [%d] [%f{1} line %l] %m'
            },
            threshold: "info"
        },
        file: {
            type: 'file', layout: {
                type: 'pattern',
                pattern: '[%p] [%d] [%f{1} line %l] %m',
            }, filename: path.join(dir, "./logs/app.log")
        }
    },

or is this workaround for that, i dont want to use multiple categories or any alternative to divide logs using a single category

Hi, there is a logLevelFilter appender that you might want to take a look at.

The below code goes into the filterErrors appender (logLevelFilter).
It then outputs to the logToFile appender (file).

log4js.configure({
  appenders: {
    console: { type: "stdout" },
    logToFile: { type: "file", filename: "only-errors.log" },
    filterErrors: {
      type: "logLevelFilter",
      appender: "logToFile", // output to logToFile appender
      level: "error",
    },
  },
  categories: {
    default: { appenders: ["filterErrors", "console"], level: "debug" },
  },
});
