Package Exports

@elastic/ecs-morgan-format

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@elastic/ecs-morgan-format) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@elastic/ecs-morgan-format

This Node.js package provides a formatter for the morgan logging middleware compatible with Elastic Common Schema (ECS) logging.
In combination with the filebeat shipper, you can send your logs directly to Elasticsearch and leverage Kibana's Logs app to inspect all logs in one single place.

Please see the Node.js ECS morgan documentation.

Install

npm install @elastic/ecs-morgan-format

Usage

const app = require('express')()
const morgan = require('morgan')
const ecsFormat = require('@elastic/ecs-morgan-format')

app.use(morgan(ecsFormat()))

app.get('/', function (req, res) {
  res.send('hello, world!')
})

app.listen(3000)

Running this script and making a request (via curl -i localhost:3000/) will produce log output similar to the following:
