    Lead maintainer: James Sumners

    pino-filter is a transport for Pino that allows filtering of log lines based on logger names, similar to the funtionality of filters in the debug module.

    Logs that match any filters are written to stdout. By default, pino-filter will pass through all received logs at the info level or higher. To define filters, a configuration file must be supplied that provides a mapping of filters to log levels. For example, you can supply a simple JSON file:

    {
      "levels": {
        "*": "info",
        "foo:bar": "debug",
        "baz:*": "trace"
      }
    }

    Usage

    $ node the-app.js | pino-filter ./config.json

    Config

    module.exports = {
      levels: {
        '*': 'info', // catch-all filter
        'foo:bar': 'debug',
        'baz:*': 'trace'
      },
      values: {
        fatal: 60,
        error: 50,
        warn: 40,
        info: 30,
        debug: 20,
        trace: 10
      }
    }
    • levels: a mapping of filters (keys) to log levels (level names). Note: the wildcard * may only be used at the end of a filter, e.g. foo:* is valid but foo:*:bar is not.
    • values: a mapping of level names to their numeric value. The default is set to the standard Pino levels. If custom levels are defined in the application, those level values should be defined here.

    Note: the configuration file can be reloaded at runtime by sending the SIGHUP signal to the pino-filter process.
