CycleCountFrom — Click element; collects differences in cycle counters
CycleCountFrom()
Batching: Batching natively supported
Ports: 1 input, 1 output
Processing: push
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.
A packet has room for either exactly one cycle count or exactly one performance metric.
- 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, andzero_countcounters to zero when written.
