How can you open many WebSocket connections and just keep them open?

Question

stress testing

What tool under Linux can just open as many WebSocket connections as possible and keep them open for a while?

Preferably without high-level NodeJS wrappers.

It is desirable that each connection randomly selects 1 from a pool of addresses to which to connect. The name is resolved into several IPs, and it is better to scatter evenly over all.

It is desirable to get a histogram of how quickly how many connections were opened, and how many were broken off.
