RUM Browser Monitoring
Overview
Datadog Real User Monitoring (RUM) enables you to visualize and analyze the real-time performance and user journeys of your application's individual users. To collect events, add the RUM Browser SDK to your browser application and configure what data is collected using initialization parameters.
Setup
The RUM Browser SDK supports all modern desktop and mobile browsers including IE11. For more information, see the Browser Support table.
To set up RUM Browser Monitoring, create a RUM application:
- In Datadog, navigate to the RUM Applications page and click the New Application button.
- Enter a name for your application and click Generate Client Token. This generates a
clientToken
and anapplicationId
for your application. - Choose the installation type for the RUM Browser SDK: npm, or a hosted version (CDN async or CDN sync).
- Define the environment name and service name for your application to use unified service tagging for RUM & Session Replay. Set a version number for your deployed application in the initialization snippet. For more information, see Tagging.
- Set the sampling rate of total user sessions collected and use the slider to set the percentage of total Browser Premium sessions collected. Browser Premium sessions include resources, long tasks, and replay recordings. For more information about configuring the percentage of Browser Premium sessions collected from the total amount of user sessions, see Configure Your Setup For Browser and Browser Premium Sampling.
- Click the Session Replay Enabled toggle to access replay recordings in Session Replay.
- Select a privacy setting for Session Replay in the dropdown menu.
- Enter a name for your application and click Generate Client Token. This generates a
- Deploy the changes to your application. Once your deployment is live, Datadog collects events from your users' browsers.
- Visualize the data collected in dashboards or create a search query in the RUM Explorer.
Until Datadog starts receiving data, your application appears as pending
on the RUM Applications page.
Choose the right installation method
npm (node package manager) : This method is recommended for modern web applications. The RUM Browser SDK is packaged with the rest of your front-end JavaScript code. It has no impact on page load performance. However, the SDK may miss errors, resources, and user actions triggered before the SDK is initialized. Datadog recommends using a matching version with the Browser Logs SDK.
CDN async : This method is recommended for web applications with performance targets. The RUM Browser SDK loads from our CDN asynchronously, ensuring the SDK download does not impact page load performance. However, the SDK may miss errors, resources, and user actions triggered before the SDK is initialized.
CDN sync : This method is recommended for collecting all RUM events. The RUM Browser SDK loads from our CDN synchronously, ensuring the SDK loads first and collects all errors, resources, and user actions. This method may impact page load performance.
npm
Add @datadog/browser-rum
to your package.json
file, then initialize it with:
import { datadogRum } from '@datadog/browser-rum'
datadogRum.init({
applicationId: '<DATADOG_APPLICATION_ID>',
clientToken: '<DATADOG_CLIENT_TOKEN>',
site: '<DATADOG_SITE>',
// service: 'my-web-application',
// env: 'production',
// version: '1.0.0',
sampleRate: 100,
premiumSampleRate: 100, // if not included, the default is 100
trackInteractions: true,
})
import { datadogRum } from '@datadog/browser-rum'
datadogRum.init({
applicationId: '<DATADOG_APPLICATION_ID>',
clientToken: '<DATADOG_CLIENT_TOKEN>',
site: '<DATADOG_SITE>',
// service: 'my-web-application',
// env: 'production',
// version: '1.0.0',
sampleRate: 100,
replaySampleRate: 100, // if not included, the default is 100
trackInteractions: true,
})
The trackInteractions
and trackFrustrations
parameters enable the automatic collection of user clicks in your application. Sensitive and private data contained on your pages may be included to identify the elements interacted with.
CDN async
Add the generated code snippet to the head tag of every HTML page you want to monitor in your application.
<script>
(function(h,o,u,n,d) {
h=h[d]=h[d]||{q:[],onReady:function(c){h.q.push(c)}}
d=o.createElement(u);d.async=1;d.src=n
n=o.getElementsByTagName(u)[0];n.parentNode.insertBefore(d,n)
})(window,document,'script','https://www.datadoghq-browser-agent.com/datadog-rum-v4.js','DD_RUM')
DD_RUM.onReady(function() {
DD_RUM.init({
clientToken: '<CLIENT_TOKEN>',
applicationId: '<APPLICATION_ID>',
site: '<DATADOG_SITE>',
// service: 'my-web-application',
// env: 'production',
// version: '1.0.0',
sampleRate: 100,
premiumSampleRate: 100, // if not included, the default is 100
trackInteractions: true,
})
})
</script>
<script>
(function(h,o,u,n,d) {
h=h[d]=h[d]||{q:[],onReady:function(c){h.q.push(c)}}
d=o.createElement(u);d.async=1;d.src=n
n=o.getElementsByTagName(u)[0];n.parentNode.insertBefore(d,n)
})(window,document,'script','https://www.datadoghq-browser-agent.com/datadog-rum-v4.js','DD_RUM')
DD_RUM.onReady(function() {
DD_RUM.init({
clientToken: '<CLIENT_TOKEN>',
applicationId: '<APPLICATION_ID>',
site: '<DATADOG_SITE>',
// service: 'my-web-application',
// env: 'production',
// version: '1.0.0',
sampleRate: 100,
replaySampleRate: 100, // if not included, the default is 100
trackInteractions: true,
})
})
</script>
The trackInteractions
and trackFrustrations
parameters enable the automatic collection of user clicks in your application. Sensitive and private data contained on your pages may be included to identify the elements interacted with.
Early RUM API calls must be wrapped in the DD_RUM.onReady()
callback. This ensures the code only gets executed once the SDK is properly loaded.
CDN sync
Add the generated code snippet to the head tag (in front of any other script tags) of every HTML page you want to monitor in your application. Including the script tag higher and synchronized ensures Datadog RUM can collect all performance data and errors.
<script src="https://www.datadoghq-browser-agent.com/datadog-rum-v4.js" type="text/javascript"></script>
<script>
window.DD_RUM &&
window.DD_RUM.init({
clientToken: '<CLIENT_TOKEN>',
applicationId: '<APPLICATION_ID>',
site: '<DATADOG_SITE>',
// service: 'my-web-application',
// env: 'production',
// version: '1.0.0',
sampleRate: 100,
premiumSampleRate: 100, // if not included, the default is 100
trackInteractions: true,
})
</script>
<script src="https://www.datadoghq-browser-agent.com/datadog-rum-v4.js" type="text/javascript"></script>
<script>
window.DD_RUM &&
window.DD_RUM.init({
clientToken: '<CLIENT_TOKEN>',
applicationId: '<APPLICATION_ID>',
site: '<DATADOG_SITE>',
// service: 'my-web-application',
// env: 'production',
// version: '1.0.0',
sampleRate: 100,
replaySampleRate: 100, // if not included, the default is 100
trackInteractions: true,
})
</script>
The trackInteractions
and trackFrustrations
parameters enable the automatic collection of user clicks in your application. Sensitive and private data contained on your pages may be included to identify the elements interacted with.
The window.DD_RUM
check is used to prevent issues if a loading failure occurs with the RUM Browser SDK.
TypeScript
Types are compatible with TypeScript >= 3.8.2. For earlier versions, import JavaScript sources and use global variables to avoid any compilation issues:
import '@datadog/browser-rum/bundle/datadog-rum'
window.DD_RUM.init({
applicationId: 'XXX',
clientToken: 'XXX',
site: 'datadoghq.com',
sampleRate: 100,
premiumSampleRate: 100,
})

Tagging
A service is an independent, deployable code repository that maps to a set of pages.
- If your browser application was constructed as a monolith, your RUM application has one service name for the application.
- If your browser application was constructed as separate repositories for multiple pages, edit the default service names throughout the lifecycle of your application.
Access internal context
After the Datadog browser RUM SDK is initialized, you can access the internal context of the SDK.
You can explore the following attributes:
| Attribute | Description | | -------------- | ----------------------------------------------------------------- | | application_id | ID of the application. | | session_id | ID of the session. | | user_action | Object containing action ID (or undefined if no action is found). | | view | Object containing details about the current view event. |
For more information, see RUM Browser Data Collected.
Example
{
application_id : "xxx",
session_id : "xxx",
user_action: { id: "xxx" },
view : {
id : "xxx",
referrer : "",
url: "http://localhost:8080/",
name: "homepage"
}
}
You can optionally use startTime
parameter to get the context of a specific time. If the parameter is omitted, the current context is returned.
getInternalContext (startTime?: 'number' | undefined)
NPM
For NPM, use:
import { datadogRum } from '@datadog/browser-rum'
datadogRum.getInternalContext() // { session_id: "xxxx", application_id: "xxxx" ... }
CDN async
For CDN async, use:
DD_RUM.onReady(function () {
DD_RUM.getInternalContext() // { session_id: "xxxx", application_id: "xxxx" ... }
})
CDN sync
For CDN sync, use:
window.DD_RUM && window.DD_RUM.getInternalContext() // { session_id: "xxxx", application_id: "xxxx" ... }
