Epsagon Instrumentation for OpenWhisk

Installation

From your project directory:

npm install --save epsagon-openwhisk

Getting started (Apache OpenWhisk)

You should pass the Epsagon token to your action as a default parameter, so that you don't have to expose important credentials in your code. The name of the parameter can be configured using token_param, in this example we use EPSAGON_TOKEN

const epsagon = require('epsagon');

function main(params) {
    // your main function
}

module.exports.main = epsagon.openWhiskWrapper(main, {
    token_param: 'EPSAGON_TOKEN', // name of the action parameter to take the token from
    appName: 'my-app-name'
    metadataOnly: false // Optional, send more trace data
});

You can then pass the EPSAGON_TOKEN as a default parameter into your action using the wsk command line client:

$ wsk action update <myaction> --parameter EPSAGON_TOKEN <your-epsagon-token>
