Helper struct to store connection timing and TLS details

Fields

connection_reused: bool

A guess at reuse: the connection was established more than 100 ms before this request. It is only a guess - a slow client or a long TLS handshake trips it on a brand-new connection - so the proxy takes the exact keepalive signal pingora gives it for HTTP/1 and applies this only to HTTP/2, where streams share one connection with no signal.

connection_time: u64

Age of the connection in milliseconds, wall clock.

tcp_established: u64

Timestamp when TCP connection was established

tls_established: u64

Timestamp when TLS handshake completed

tcp_connect: Option<u64>

TCP connect time in milliseconds, measured by pingora on a monotonic clock. Only a connection this side opened has one; an accepted connection reports None.

tls_handshake: Option<u64>

TLS handshake time in milliseconds, measured by pingora on a monotonic clock around the handshake itself; None without TLS or when it was not measured.

connect_offload_wait: Option<u64>

Time the connect spent queued for an offload thread, in milliseconds. None unless the connect was offloaded.

tls_version: Option<Cow<'static, str>>

TLS protocol version if using HTTPS

tls_cipher: Option<Cow<'static, str>>

TLS cipher suite in use if using HTTPS
