recordNewConnectionSetupLatency

public void recordNewConnectionSetupLatency(double latencyMs,
 VeniceConnectionSource source)

Record the SSL handshake setup latency with connection source dimension. Called from the background scanner thread (same place as connection count metrics) after the connection source is identified via principal extraction.

Parameters:

latencyMs - the setup latency in milliseconds, computed at handshake completion

source - whether the connection is from a router or a client
