log4bro
- log4bro makes it hassle free to have compliant microservice ELK stack log behaviour
- just require & init and log via global variable in a few seconds
- you can run in production mode to automatically switch log-levels
- you can run in dockerMode to stop logfile writing and change output to json fields
- you can attach some extra fields to json logs so that they are also loved by your ELK stack and your sysops
- node + docker + log4bro = happy you, happy ELK stack and happy sysops
- comes batteries included for express.js users (check /examples/express_example.js)
- auto. access log in ELK format (cout or file)
- switch log-level dynamically example:
global.LOG.changeLogLevel("INFO");
simple example
const Logger = require("log4bro"); const options = { productionMode: true, //switches loglevel between DEBUG and WARN logDir: "logs", //relative directory to write log file to silence: false, //silences logger loggerName: "dev", //ignore dockerMode: true, //disables output to logfile varKey: "LOG" //name of global variable}; const logger = new Logger(options); LOG.trace("bla");LOG.debug("bla");LOG.info("bla");LOG.warn("bla");LOG.error("bla");LOG.fatal("bla");
