Statistics

Statistics for Chimera ports.

Clear Counter

Clear all the impairment (duplicate, drop, mis-ordered, corrupted, latency and jitter) statistics for a Chimera port and flows on the port. The byte and packet counts will restart at zero.

Corresponding low-level API class: PE_CLEAR

await port.emulation.clear.set()

Corruption

Obtains statistics concerning all the packets corrupted on between this receive port and its partner TX port.

Corresponding low-level API class: PE_CORTOTAL

port_corrupted = await port.emulation.statistics.corrupted.get()
port_corrupted.fcs_corrupted_pkt_count
port_corrupted.fcs_corrupted_pkt_ratio
port_corrupted.ip_corrupted_pkt_count
port_corrupted.ip_corrupted_pkt_ratio
port_corrupted.tcp_corrupted_pkt_count
port_corrupted.tcp_corrupted_pkt_ratio
port_corrupted.total_corrupted_pkt_count

port_corrupted.udp_corrupted_pkt_ratio

Drop Counter

Obtains statistics concerning all the packets dropped between this receive port and its partner TX port.

Corresponding low-level API class: PE_DROPTOTAL

port_drop = await port.emulation.statistics.drop.get()
port_drop.pkt_drop_count_total
port_drop.pkt_drop_count_programmed
port_drop.pkt_drop_count_bandwidth
port_drop.pkt_drop_count_other
port_drop.pkt_drop_ratio_total

Duplication Counter

Obtains statistics concerning all the packets duplicated between this receive port and its partner TX port.

Corresponding low-level API class: PE_DUPTOTAL

port_duplicated = await port.emulation.statistics.duplicated.get()
port_duplicated.pkt_count
port_duplicated.ratio

Jittered Counter

Obtains statistics concerning all the packets jittered between this receive port and its partner TX port.

Corresponding low-level API class: PE_JITTERTOTAL

port_jittered = await port.emulation.statistics.jittered.get()
port_jittered.pkt_count
port_jittered.ratio

Delay Counter

Obtains statistics concerning all the packets delayed this receive port and its partner TX port.

Corresponding low-level API class: PE_LATENCYTOTAL

port_delayed = await port.emulation.statistics.latency.get()
port_delayed.pkt_count
port_delayed.ratio

Misordering Counter

Obtains statistics concerning all the packets mis-ordered between this receive port and its partner TX port.

Corresponding low-level API class: PE_MISTOTAL

port_misordered = await port.emulation.statistics.mis_ordered.get()
port_misordered.pkt_count
port_misordered.ratio
