How to scan a segment

This guide shows you how to trigger an ad-hoc scan on a segment so that AlloyScan refreshes its list of discovered devices without waiting for the segment's schedule.

Prerequisites

  • Administrator role, or User role with permission to start scans.
  • A Segment ready for its execution location: an active Audit Service for local execution, or compatible, enabled cloud credentials for a supported provider Segment using a cloud worker.
  • For local network scans, the required ports are open between the Audit Service host and the target devices. See Required Ports Reference.

Steps

  1. Navigate to Network > Segments.
  2. Click the segment name to open its detail view.
  3. In the left rail of the Segment Open view, click Scan.
  4. AlloyScan queues a scan task. You can monitor it in Admin Center > Tasks and services > Active tasks while it runs.

For a segment using Local Audit service, a missing or inactive service can prevent scanning. Assign or restore an active Audit Service.

Verify

After the scan completes:

  • The Scan Results grid in the Segment Open view refreshes with discovered devices.
  • The Last scan timestamp updates.
  • The Last scan statistics panel shows Total discovered, Ignored, New nodes, and Known inventory counters.
  • A new row appears in Admin Center > Logs > Scan log with Initiator set to your account, Scope set to the segment name, and Status set to Finished. Open the log entry to inspect any diagnostic messages.
