  title: Dynatrace Export Logs for SIEM Forwarding
  summary: Aggregate logs to size the export, then bulk-export the matching records page by page.
  description: >-
    Prepares a bulk log extract for an external SIEM or archive. The workflow
    first aggregates the matching logs to understand the volume per group, then
    runs the slice-based bulk export endpoint to retrieve the first page of
    records along with the cursor for continued pagination. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
