[OVN][Neurton] Help in capturing metrics part of scale testing in OVN

Hello Team Myself new to OVN with Openstack ( provider network based model) , as part of this I am trying to perform an iperf based network test to understand how traffic flow is happening. As part of that, how to validate how much time took for logical flow computation by services in hypervisor. For specific tests, looking for a way to figure out, how much services like ovn-controller, vswitchd & ovsdb server are contributing to it . Do we have any specific tooling to capture these metrics ? Can you please help with this ? Regards, Keerthivasan
