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

• 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.

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

   kill -s SIGUSR1 <PID>
  

• Send SIGUSR2 signal to your running node program to increase log level:

   kill -s SIGUSR2 <PID>
  

• You can also pass a single logger instance to add:

   sigyan.add(logger);
