You must provide the following four variables when creating a Coralogix logger instance.

Private Key – A unique ID that represents your company. The private key can be found under ‘settings’->’ send your logs’. It is located in the upper left corner.

Application Name – The name of your environment, for example, a company named “SuperData” would probably insert the “SuperData” string parameter or if they want to debug their test environment they might insert the “SuperData– Test”.

SubSystem Name – Your application probably has multiple components, for example: Backend servers, Middleware, Frontend servers etc. in order to help you examine the data you need, inserting the subsystem parameter is vital.

For more information on how to setup and use Winston head over to our guide as well as the Winston repository.

If your Coralogix account top level domain is not ‘.com’ set the following environment variable
CORALOGIX_URL=https://api.Cluster URL/api/v1/logs
npm install –save coralogix-logger-winston

Winston usage example:

var winston = require("winston");
    var CoralogixWinston = require("coralogix-logger-winston");
    // global configuration for coralogix 
    var config = {
        privateKey: "your-private-key",
        applicationName: "YOUR APP NAME",
        subsystemName: "YOUR SUBSYSTEM",
    // configure winston to user coralogix transport 
        transports: [new CoralogixWinston.CoralogixTransport({
            category: "YOUR CATEGORY",
            handleExceptions: true
    // use winston 
    winston.info("use winston to send your logs to coralogix");
