### What did you do?

Open the [Logs Anthropic] Audit Overview dashboard and review the Top Related IPs dashboard panel.

### What did you see?

This dashboard panel is a duplicate of Top Actors and aggregates based on user.name rather than an IP address.

### What did you expect to see?

This dashboard should have IP addresses not Actors as the aggregate field.

### Anything else?

_No response_

Start with the Anthropic integration's Logs Anthropic Audit Overview dashboard and compare the Top Related IPs panel with Top Actors. Confirm which field each panel aggregates, then update the panel so it uses an IP address field and verify that the displayed values are IP addresses rather than actors.
