Yes. See: https://github.com/owebeewan/wan-perftest/blob/master/gateway/src/main/java/io/pivotal/gateway/filter/TimingGatewayEventFilter.java
There are two types of latency in the WAN gateway: 1) queue time and 2) transmit time. Barry Oglesby provided a class that captures both metrics and I wrote a performance test project that uses it. Transmit time is defined as the send time AND the ack time. You define this event filter as follows: https://github.com/owebeewan/wan-perftest/blob/46f8c76e96e06265215f460dff5aeaf1a07bee49/DataCenter1/cluster.sh#L25 You define the jar in the server startup https://github.com/owebeewan/wan-perftest/blob/46f8c76e96e06265215f460dff5aeaf1a07bee49/DataCenter1/startall.sh#L10 Source was Barry Oglesby.
