Monitoring signals

Signal	What it shows
Request volume	How many requests the connection sends over time.
Success rate	The share of requests that complete successfully.
Latency	How long Pxxl takes to authorize and serve requests.
Popular methods	The tools and methods the client uses most.
Transfer usage	The amount of data sent and returned.

Request history

Request history records method, tool, status, duration, and byte counts. It does not store request or response bodies. Use it to find blocked calls and slow operations without creating a second copy of resource data.

Investigate a failed request

Check whether the response was 401 or 403.
For 401, confirm the key is current and the client sends it as an HTTP header.
For 403, open Permissions and check the scope and resource allowlist.
If the request succeeded but was slow, compare its method and resource with the latency view.

Safe operations

Monitoring data is metadata about the connection. It is not a transcript of prompts, tool arguments, or returned records.
