Struct ObservabilityConfig 

#[non_exhaustive]
pub struct ObservabilityConfig {
    pub log_level: String,
    pub log_format: String,
    pub audit_log_path: Option<PathBuf>,
    pub log_request_headers: bool,
    pub metrics_enabled: bool,
    pub metrics_bind: String,
}

Observability settings (reusable across MCP projects).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

log_level: String

tracing log level / env filter string (e.g. info,rmcp_server_kit=debug).

log_format: String

Log output format: json or text.

audit_log_path: Option<PathBuf>

Optional path to an append-only audit log file.

log_request_headers: bool

Emit inbound HTTP request headers at DEBUG level in transport logs. Sensitive headers remain redacted when enabled.

metrics_enabled: bool

Enable the Prometheus metrics endpoint.

metrics_bind: String

Bind address for the Prometheus metrics listener.
