Configuration selecting which encoder to use for a scenario.

This enum is serde-deserializable from YAML scenario files. The type field selects the variant: prometheus_text, influx_lp, json_lines, syslog, remote_write, or otlp.

Feature-gated encoders (remote_write, otlp) have companion *Disabled variants that are compiled in when their feature is absent. These accept the YAML tag so that deserialization succeeds with a descriptive error from create_encoder instead of a generic “unknown variant” error from serde.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PrometheusText

Prometheus text exposition format (version 0.0.4).

precision optionally limits the number of decimal places in metric values.

Fields

precision: Option<u8>

Maximum decimal places for metric values. None preserves full f64 precision.

InfluxLineProtocol

InfluxDB line protocol.

field_key sets the field key used for the metric value. Defaults to "value". precision optionally limits the number of decimal places in metric values.

Fields

field_key: Option<String>

The InfluxDB field key for the metric value. Defaults to "value" if absent.

precision: Option<u8>

Maximum decimal places for metric values. None preserves full f64 precision.

JsonLines

JSON Lines (NDJSON) format.

Each event is serialized as one JSON object per line. Compatible with Elasticsearch, Loki, and generic HTTP ingest endpoints.

precision optionally rounds the metric value before JSON serialization.

Fields

precision: Option<u8>

Maximum decimal places for metric values. None preserves full f64 precision.

Syslog

RFC 5424 syslog format.

Encodes log events as syslog lines. hostname and app_name default to "sonda".

Fields

hostname: Option<String>

The HOSTNAME field in the syslog header. Defaults to "sonda".

app_name: Option<String>

The APP-NAME field in the syslog header. Defaults to "sonda".

RemoteWriteDisabled

Placeholder variant when the remote-write feature is not compiled in.

Deserializes the remote_write YAML tag so that the error message can point the user at the missing feature flag instead of producing a generic “unknown variant” error from serde.

OtlpDisabled

Placeholder variant when the otlp feature is not compiled in.

Deserializes the otlp YAML tag so that the error message can point the user at the missing feature flag instead of producing a generic “unknown variant” error from serde.
