rum

Datadog browser rum library.

Setup

NPM

import { datadogRum } from '@datadog/browser-rum'
datadogRum.init({
  applicationId: 'XXX',
  clientToken: 'XXX',
  site: 'datadoghq.com',
  resourceSampleRate: 100,
  sampleRate: 100
})

Bundle

<script src = 'https://www.datadoghq-browser-agent.com/datadog-rum.js'>
<script>
  window.DD_RUM.init({
    applicationId: 'XXX',
    clientToken: 'XXX',
    site: 'datadoghq.com',
    resourceSampleRate: 100,
    sampleRate: 100
  });
</script>

Public API

• Init must be called to start the tracking

  • Configurable options:

    • sampleRate: percentage of sessions to track. Only tracked sessions send rum events.
    • resourceSampleRate: percentage of tracked sessions with resources collection.
    • site: The site of the Datadog intake to send SDK data to (default: 'datadoghq.com', set to 'datadoghq.eu' to send data to the EU site)
    • silentMultipleInit: prevent logging errors while having multiple Init
    • trackInteractions: collect actions initiated by user interactions
    • service: name of the corresponding service
    • env: environment of the service
    • version: version of the service
    • allowedTracingOrigins: list of string or regexp of request origins in which to inject tracing headers

  • Options that must have matching configuration when also using logs SDK:

    • trackSessionAcrossSubdomains: preserve session across subdomains of the same site (default: false)
    • useSecureSessionCookie: use a secure session cookie. This will disable rum events sending on insecure (non-HTTPS) connections. (default: false)
    • allowThirdPartyContextExecution: use a secure cross-site session cookie. This will allow the Logs SDK to run when the site is loaded from another one (ex: via an iframe). Implies useSecureSessionCookie. (default: false)

  init(configuration: {
      applicationId: string,
      clientToken: string,
      site?: string,
      resourceSampleRate?: number
      sampleRate?: number,
      silentMultipleInit?: boolean,
      trackInteractions?: boolean,
      service?: string,
      env?: string,
      version?: string,
      allowedTracingOrigins?: Array<String|Regexp>,
      trackSessionAcrossSubdomains?: boolean,
      useSecureSessionCookie?: boolean,
      useCrossSiteSessionCookie?: boolean,
  })

• Modify the global context

  addRumGlobalContext (key: string, value: any)  # add one key-value to the default context
  removeRumGlobalContext (key: string)  # remove one key of the default context
  setRumGlobalContext (context: Context)  # entirely replace the default context

• Add user action

  addUserAction (name: string, context: Context)

Declarative API

Click action naming

The RUM library is using various strategies to get a name for click actions, but if you want more control, you can define a data-dd-action-name attribute on clickable elements (or any of their parents) that will be used to name the action. Examples:

<a class="btn btn-default" href="#" role="button" data-dd-action-name="Login button">Try it out!</a>

<div class="alert alert-danger" role="alert" data-dd-action-name="Dismiss alert">
  <span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span>
  <span class="sr-only">Error:</span>
  Enter a valid email address
</div>

TypeScript support

Types are compatible with TypeScript >= 3.0. For earlier version, you can import js sources and use global variable to avoid any compilation issue:

import '@datadog/browser-rum/bundle/datadog-rum';

window.DD_RUM.init({
  applicationId: 'XXX',
  clientToken: 'XXX',
  site: 'datadoghq.com',
  resourceSampleRate: 100,
  sampleRate: 100
});
