On-demand packet redirection

A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a computer system, cause the computer system to perform a method of performance management, the method comprising:

• receiving, at a port of a router that is implemented by a virtual router on an edge node of a logical network, a transport control protocol (TCP) or user datagram protocol (UDP) packet generated by a performance component of the router;
• identifying, by the router, a rule related to the TCP or UDP packet, wherein the rule causes all TCP or UDP traffic received at the port of the router from the performance component of the router to be forwarded to an interface of a kernel of an operating system (OS) running on the edge node;
• forwarding, by the router, the packet to the interface of the kernel based on the rule;
• receiving, by the performance component, in response to the TCP or UDP packet, an additional packet from the interface of the kernel;
• and
• determining, by the performance component, a performance metric based on the TCP or UDP packet and the additional packet.
