Abstract
A method for measuring latency of a data packet attributable to transit of the data packet through a distributed gateway includes transmitting, from a first virtual machine of a plurality of virtual machines executing different instances of a gateway, a ping request to each of the other virtual machines. A ping reply is received at the first virtual machine in association with each of the transmitted ping requests, and the first virtual machine measures a round-trip transit (RTT) time between transmission of each one of the ping requests and receipt of the corresponding ping response. The method further provides for publishing a latency statistic for the distributed gateway that is generated based on an aggregation of the RTT times measured by the first virtual machine.
