Health Check Routes

In addition to system information, if a collection of routes are specified DADI Status will send a request to each one and return data about the response:

  "routes": [
      "route": "/movies/latest",
      "status": 200,
      "responseTime": 0.039,
      "healthStatus": "Green"

User-Agent identifier

DADI Status passes a User-Agent header to idenitify itself when making health check requests. The following header is used:

'User-Agent': '@dadi/status'



npm install @dadi/status --save

Add a route

var dadiStatus = require('@dadi/status')

app.use('/api/status', function(req, res, next) {
  var params = {
    site: "WC?",
    package: '@dadi/web',
    version: version,
    healthCheck: {
      baseUrl: '',
      authorization: 'Bearer 123abcdef',
      routes: [{
        route: '/movies/latest',
        expectedResponseTime: 10

  dadiStatus(params, function(err, data) {
    if (err) return next(err)
    var resBody = JSON.stringify(data, null, 2)

    res.statusCode = 200
    res.setHeader('Content-Type', 'application/json')
    res.setHeader('content-length', Buffer.byteLength(resBody))
