It appears that if a server is configured to send the PROXY protocol *and* the server does not have a `check port` set, the agent check will always send the PROXY protocol. This doesn't seem to be documented anywhere, and it's kind of strange (especially since non-agent checks have the check-send-proxy flag available to control whether the PROXY protocol is emitted).
It's not hard to make my agent support receiving the PROXY protocol, but it's kind of strange, since nothing's actually being proxied. Thoughts? -- James Brown Engineer
