Configuration

See sample.config.yaml for configuration options.

Event types are configured via environment variables:

  • DATADOG_EVENT_SITE - Division where Datadog account is registered
  • DATADOG_EVENT_API_KEY - API key used to send requests to Datadog API

Finding the Telegram Group Chat ID

To integrate Telegram events with the Observer, you need the Telegram group chat ID. Here's how you can find it:

1. Open Telegram Web.
2. Navigate to the group chat for which you need the ID.
3. Look at the URL in the browser's address bar; it should look something like https://web.telegram.org/a/#-1111111111.
4. The group chat ID is the number in the URL, including the - sign if present (e.g., -1111111111).

Use this ID in the publishers.yaml configuration to correctly set up Telegram events.
