This document includes cluster-dependent URLs. Each URL has a variable part (in Italics). Match this part with a row entry within the table below. Copy the table row entry located under the column that matches the top level domain of your Coralogix account (.com, .in, etc.). Replace the variable part of the URL with this entry.

npm install --save coralogix-logger


Provide the following four variables when creating a Coralogix logger instance:

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

Private Key – Your Coralogix Send-Your-Data API key

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

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

If your Coralogix account top level domain is not ‘.com’, add the following environment variable, CORALOGIX_URL=https://ingress.Cluster URL/api/v1/logs

Cluster locationCluster URL

Import Coralogix’s package and send logs in a stateless fashion.
Note that the privateKey, severity, applicationName, subsystemName and text properties are mandatory.

Node.js implementation example:

// set the CORALOGIX_URL environmental variable if your team URL different than <team>.coralogix.com
// process.env.CORALOGIX_URL = 'https://ingress.Cluster URL/api/v1/logs';

var Coralogix = require("coralogix-logger");
    // global confing for application name, private key, subsystem name 
    const config = new Coralogix.LoggerConfig({
        applicationName:"node tester",
        subsystemName:"node tester sub",
    // create a new logger with category 
    const logger = new Coralogix.CoralogixLogger("My Category");
    // create a log 
    const log = new Coralogix.Log({
        text:"log data"
    // send log to coralogix
