winston

I am using winston to add log details in node.js, i used the following procedure to add the logs var winston = require('winston'); winston.remove(winston.transports.Console); winston.add(winston.transports.Console, {'timestamp':true,'colorize':true); winston.log('info','jjjj'); the output that i got is 2012-12-21T09:32:05.428Z - info: jjjj I need to specify a format for mytimestamp , is there any provision to do so in winston any help will be much appreciated Ben Evans The timestamp option can be a function that returns what you wish it to be saved as... Line 4: winston.add(winston.transports

When I create a nodejs winston console logger and set json:true , it always output JSON logs in multiline format. If I pipe these to a file and try to grep that file, my grep hits only include part of the log line. I want winston to output my log lines in JSON format, but not to pretty print the JSON Here is my config (coffeescript, apologies): winston = require 'winston' logger = new (winston.Logger)( transports: [ new winston.transports.Console({ json: true }) ] ) And some sample output: { "name": "User4", "level": "info", "message": "multi line whyyyyy" } winston 3.x (current version)

My logger is set up like: const myFormat = printf(info => { return `${info.timestamp}: ${info.level}: ${info.message}: ${info.err}`; }); const logger = winston.createLogger({ level: "info", format: combine(timestamp(), myFormat), transports: [ new winston.transports.File({ filename: "./logger/error.log", level: "error" }), new winston.transports.File({ filename: "./logger/info.log", level: "info" }) ] }) Then I am logging out some error like this: logger.error(`GET on /history`, { err }); How is it possible to log the full stack trace for errors to via the error transport? I tried passing in

I want to add timestamp to logs. What is the best way to achieve this? imagreenplant I was dealing with the same issue myself. There are two ways I was able to do this. When you include Winston, it usually defaults to adding a Console transport. In order to get timestamps to work in this default case, I needed to either: Remove the console transport and add again with the timestamp option. Create your own Logger object with the timestamp option set to true. The first: var winston = require('winston'); winston.remove(winston.transports.Console); winston.add(winston.transports.Console, {

I am using forever to run my node application. When I start forever I specify where to write the logs. I also specify to append to the log. Problem here is that my log is going to grow out of control over the course of months. Is there any way to archive/roll logs on an interval, i.e. every day roll/archive what is in the log file to another file (i.e. server-2013-3-5.log). That way I can delete/move off old log files as needed. I have just started looking into using Winston for my logger and I have not come across anything there that would help. Any ideas? mak forever itself doesn't support

It seems nice for API's, scripts and what not. But reading a winston json stack trace is very hard with a text editor. E.g. {"level":"info","message":"starting","timestamp":"2014-05-14T15:45:44.334Z"} {"date":"Wed May 14 2014 08:45:45 GMT-0700 (Pacific Daylight Time)","process":{"pid":8804,"uid":null,"gid":null,"cwd":"C:\\data\\mytool","execPath":"C:\\Program Files\\nodejs\\node.exe","version":"v0.10.21","argv":["node","C:\\data\\mytool\\server"],"memoryUsage":{"rss":45199360,"heapTotal":32171264,"heapUsed":15158096}},"os":{"loadavg":[0,0,0],"uptime":70496.6138252},"trace":[{"column":null,
