Configuring Logs for Node.js

Configuring Node.js Logging
Enabling Log Plugin
By default, log monitoring is disabled, but it can be enabled by setting the relevant configuration parameters. These parameters include the thundra_agent_lambda_log_disable environment variable and the disable_log object initialization parameter.
Enabling log programmatically on agent initialization
Programmatic Log Plugin Configuration
const thundra = require("@thundra/core")({ 
  logConfig: {
    enabled: false,
  },
});
Enabling log using environment variables
Log Plugin Configuration via Environment Variables
thundra_apiKey: ${self:custom.thundraApiKey}
thundra_agent_lambda_log_disable: false
Creating the Thundra Logger
In order to use Thundra's log support, you need to simply write “require” from the @thundra/core package, and use the createLogger method.
Configure the Thundra Logger
const thundra = require('@thundra/core');
const logger = thundra.createLogger();
When configuring your loggers, you can also set tag names so you can easily identify any logs that your functions may generate. The default name when setting up your log is default, but this can be changed as shown below:
Configure the Thundra Logger Name
const thundra = require('@thundra/core');
const logger = thundra.createLogger({
    loggerName: 'fooLogger'
});
Using the Thundra Logger
Using Thundra's Node.js logger, you can easily log variables, exceptions, and warnings and access those logs in the Thundra Web Console rather than CloudWatch Logs.
You can log in two different ways:
Using the trace, debug, info, warn, error, and fatal methods. All these methods support the printf-like format, which is the same as Node.js's util.format.
const thundra = require('@thundra/core');
const logger = thundra.createLogger();
​
exports.handler = thundra()((event, context, callback) => {
    logger.trace('Hello %s', 'Thundra');
    logger.debug('Hello %s', 'Thundra');
    logger.info('Hello %s', 'Thundra');
});
Using the log method, as demonstrated in the code snippet shown below.
Using the log method
const thundra = require("@thundra/core")
const logger = thundra.createLogger();
​
exports.handler = thundra()((event, context, callback) => {
    logger.log({
        level: "trace",
        message: "Hey, I am tracing",
    });
 
    //or directly use as
    logger.log("trace","Hey, I am %s","tracing");
});
