CycleCountFrom Element Documentation

NAME

CycleCountFrom — Click element; collects differences in cycle counters

SYNOPSIS

CycleCountFrom()

Batching: Batching natively supported
Ports: 1 input, 1 output
Processing: push

DESCRIPTION

Incoming packets should have their cycle counter annotation set. Measures the current value of the cycle counter, and keeps track of the total accumulated difference. Packets whose cycle counter annotations are zero are not added to the count or difference.

NOTES

A packet has room for either exactly one cycle count or exactly one performance metric.

ELEMENT HANDLERS

• count (read-only) — Returns the number of packets that have passed.
• cycles (read-only) — Returns the accumulated cycles for all passing packets.
• zero_count (read-only) — Returns the number of packets with zero-valued cycle counter annotations that have passed. These aren't included in the count.
• reset_counts (write-only) — Resets count, cycles, and zero_count counters to zero when written.
