Remote captures allow administrators to collect packet captures (PCAPs) and WARP diagnostic logs directly from end user devices. This data can be used to troubleshoot network problems, investigate security incidents, and identify performance bottlenecks.

-
1. In [Zero Trust](https://one.dash.cloudflare.com/), go to **DEX** > **Remote captures**.
34
-
2. Select up to 10 devices that you want to run a capture on. Devices must be [registered](/cloudflare-one/connections/connect-devices/warp/deployment/) in your Zero Trust organization.

3. Configure the types of captures to run.

-**WARP Diagnostics Logs**: Generates a [WARP diagnostic log](/cloudflare-one/connections/connect-devices/warp/troubleshooting/warp-logs/#warp-diag-logs) of the past 96 hours. To include a routing test for all IPs and domains in your [Split Tunnel configuration](/cloudflare-one/connections/connect-devices/warp/configure-warp/route-traffic/split-tunnels/), select **Test all routes**.
