If you have not set up the Datadog Browser SDK yet, follow the in-app setup instructions or see the Browser Logs setup documentation.

1. Download the latest version of the Logs Browser SDK. Error Tracking requires at least v4.36.0.

2. Configure your application’s version, env, and service when initializing the SDK. For example, with NPM:

   import { datadogLogs } from '@datadog/browser-logs'
   
   datadogLogs.init({
     clientToken: '<DATADOG_CLIENT_TOKEN>',
     site: '<DATADOG_SITE>',
     service: '<MY_SERVICE>',
     env: '<MY_ENV>',
     forwardErrorsToLogs: true,
     sessionSampleRate: 100,
   })
   

3. To log a caught exception yourself, you may use the optional error parameter:

   try {
     throw new Error('wrong behavior');
   } catch(err) {
     datadogLogs.logger.error("an error occurred", {usr: {id: 123}}, err);
   }
   

Note: Error Tracking only considers errors that are instances of Error.

If you have not set up the Datadog Android SDK yet, follow the in-app setup instructions or see the Android Logs setup documentation.

1. Download the latest version of the Datadog Android SDK for Logs.

2. Configure your application’s version, env, and service when initializing the SDK.

3. To log a caught exception yourself, you may optionally use:

   try {
     doSomething();
   } catch (IOException e) {
     logger.e("an exception occurred", e);
   }
   

If you have not setup the Datadog iOS SDK yet, follow the in-app setup instructions or see the iOS Logs setup documentation.

1. Download the latest version of the Datadog iOS SDK for Logs.

2. Configure your application’s version, env, and service when initializing the SDK.
