Struct ObservabilityConfig 

pub struct ObservabilityConfig {
    pub enabled: bool,
    pub exporter: TelemetryExporterKind,
    pub endpoint: Option<String>,
    pub service_name: Option<String>,
    pub log_file_max_bytes: u64,
}

Configuration for structured observability export, and for the daemon’s own log file.

Export is off by default: telemetry costs a background export pipeline and most interactive users have the dashboard instead. When enabled, spans, metrics and log records for every run flow to the configured exporter.

Example config:

[observability]
enabled = true
exporter = "otlp"
endpoint = "http://localhost:4318"
service_name = "leviath"
log_file_max_bytes = 5242880

Fields

enabled: bool

Whether to export telemetry at all (default: false).

exporter: TelemetryExporterKind

Which exporter to use (default: otlp).

endpoint: Option<String>

OTLP endpoint. Falls back to OTEL_EXPORTER_OTLP_ENDPOINT, then to http://localhost:4318 - the OTLP HTTP port. Leviath exports OTLP over HTTP/protobuf, not gRPC, so a collector’s 4317 gRPC endpoint will not work here.

service_name: Option<String>

The service.name resource attribute. Falls back to OTEL_SERVICE_NAME, then to "leviath".

log_file_max_bytes: u64

Bytes a log file Leviath writes for itself may reach before it is rolled to <name>.1, replacing the previous one: the daemon’s daemon.log and each lev serve’s serve-<name>.log, under the data directory. 0 never rolls. Default: 5 MiB.

Trait Implementations

impl Clone for ObservabilityConfig

fn clone(&self) -> ObservabilityConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ObservabilityConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ObservabilityConfig

fn default() -> Self

Export off, the OTLP exporter when it is turned on, and the default log cap. Hand-written so the empty-table serde default and Default agree on the cap.

impl<'de> Deserialize<'de> for ObservabilityConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ObservabilityConfig

impl PartialEq for ObservabilityConfig

fn eq(&self, other: &ObservabilityConfig) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for ObservabilityConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
