Napatech’s implementation of the pcap_stat capture statistics counters.
Napatech's implementation
| Counter | Description |
|---|---|
| ps_recv | Counts the number of packets received by libpcap before the PCAP filter. |
| ps_drop | Counts all packets dropped by the NT Driver software. Packets might be dropped if streams are shared and opened with host buffer allowance < 100%. |
| ps_ifdrop | Counts the number of packets lost due to host buffer overrun for the actual stream. If multiple host buffers are attached to the stream ID used in the actual libpcap device (merging), the individual drop counters are combined into this ps_ifdrop counter. |
