6.2.11.2. Stratix 10 Packet Tracing, Profiling, and Statistics

Packet probes perform both tracing and statistic collection over packets passing through “links” connected to the probe.

Tracing can be fine-tuned through a Filter or a combination of Filters. Packets matching filter criteria is sent to the observer (to be forwarded to the ATB bus). Trace alarms can also be raised when packets match filter criteria. Trace Alarms are software readable registers on the system interconnect.

Statistics collection is done by setting up counters that track the number of packets matching certain criteria going through a link. Alarms can also be set when a statistic count hit a certain level.

The following table shows how each packet probe is configured.
