Struct MetricsSnapshot 

pub struct MetricsSnapshot {
    pub connections: u64,
    pub connections_refused_total: u64,
    pub commands_total: u64,
    pub commands_error_total: u64,

}

One consistent-enough read of the listener’s counters (SRV-030), exporter-agnostic by design.

Fields

connections: u64

Currently open connections (gauge).

connections_refused_total: u64

Accepts refused at the max_connections ceiling.

commands_total: u64

Responses written, success or error.

commands_error_total: u64

Error responses written.

command_duration_microseconds_total: u64

Total dispatch time across all commands, microseconds.

frame_bytes_in_total: u64

Request bytes as counted by the decoder’s length prefix (SRV-007).

frame_bytes_out_total: u64

Response/push bytes as counted from the encoded buffers (SRV-007).

slow_commands_total: u64

Commands slower than the configured threshold (SRV-030).

non_hello_first_frames_total: u64

Connections whose first frame was not a canonical HELLO — the lead-with-HELLO adoption signal (SPEC-008 handshake section).
