Support Multiple Datadog Browser Log Instances with Independent Session Management

[naseemkullah]

Problem Statement

In monolithic frontend applications where multiple teams require distinct Datadog browser log instances, the current session management (based on a shared cookie) prevents setting unique sample rates and configurations for each instance. This limitation affects our ability to monitor different functionalities independently, as the sample rate and session data are applied globally across all instances, rather than on a per-instance basis.

Proposed Solution

Introduce a cookieName or namespace parameter for datadogLogs.init, allowing each instance to maintain isolated session data, sample rates, and configurations. By providing unique identifiers, teams could independently monitor specific functionalities without global session overlap.

Potential API:

datadogLogs.init({
  clientToken: 'your-client-token',
  site: 'datadoghq.com',
  service: 'my-service',
  sampleRate: 50,
  cookieName: 'dd_logs_teamA', // Custom cookie for team A's logs
  namespace: 'teamA_logs',     // Alternative: unique namespace
});

This change would enhance Datadog's usability for large, multi-team applications by supporting more granular, instance-specific logging configurations.
