Serverless Metrics (WIP)

Get KPIs for API Gateway + Lambda

Why - AWS API Gateway + Lambda is a great stack for developing serverless apps. Currently, trying to get a good overview of whats going on with your service is very difficult.

This project's goal is to let you easily get key metrics about your serverless service, for each resource + method of your gateway:

• Calls to API Gateway
• Errors returned by API Gateway
• Lambda Invocations
• Lambda Errors
• Lambda Throttles

Installation

npm i --save serverless-metrics

Usage

const ServerlessMetrics = require('serverless-metrics')
const HOURS_TO_GET = 5 // default 24
ServerlessMetrics.getGatewayMetrics('gateway_id', 'stage_name', HOURS_TO_GET)
  .then(function(data) {
    console.log(data)
  })
  .catch(console.error)
/* Returns
