Setting Up Log Management

1. Configure your application or services to send logs to Datadog.
2. Use the Datadog Agent to collect logs from your environment.
3. Analyze and visualize logs in the Logs section of the Datadog dashboard.

Synthetics

Synthetics allows you to create and run automated tests to monitor the availability and performance of your web applications and APIs. This helps you ensure that your services are running smoothly and meet user expectations.

Setting Up Synthetics

1. Navigate to the Synthetics section in the Datadog dashboard.
2. Create a new test by specifying the type (e.g., browser test, API test).
