Sigyan

Sigyan is a small utility to change levels of Bunyan logger instances using SIGUSR1/SIGUSR2 POSIX signals. (See sigaction(2) for more information on POSIX signals).

Usage

  1. Include in your node program and indicate which loggers to modify when a signal is received:

    var sigyan = require('sigyan');
    sigyan.add([LOG, backend.log]);
    

Note LOG and backend.log are bunyan logger instances here.

  1. Send SIGUSR1 signal to your running node program to decrease log level:

    kill -s SIGUSR1 <PID>
    
  2. Send SIGUSR2 signal to your running node program to increase log level:

    kill -s SIGUSR2 <PID>
    
  3. You can also pass a single logger instance to add:

    sigyan.add(logger);
