Abstract
Techniques are described herein that are capable of monitoring connectivity and latency of network links in virtual networks. For instance, a ping agent injects first ping packets into network traffic on behalf of hosts in the virtual network. The ping agent monitors incoming packets to identify first ping response packets, which are in response to the first ping packets, among the incoming packets. A ping responder rule that is included in inbound packet filter rules for a port in a virtual switch intercepts second ping packets in the network traffic. The ping responder rule converts the second ping packets into second ping response packets and injects the second ping response packets into outbound packet filter rules to be transferred to sources from which the second ping packets are received.
