Overview

A SIEM streaming forwarder configured on the customer’s account.

Active-record style: instantiate via client.audit.forwarders.new(…), mutate fields directly, and call #save to persist or #delete to remove. Header values in configuration.headers are returned redacted on reads — the GET path on the audit API replaces every header value with “<redacted>”. Re-supply real values before calling #save; the SDK does not cache them client-side.

end

#enabled ⇒ Boolean

Returns Read-only. Always false — the base enablement is pinned off. Whether a forwarder actually delivers is decided per environment via #environments; mutating this field has no effect on the server.

Returns:

  • (Boolean) —

end

#environments ⇒ Hash{String => ForwarderEnvironment}

Returns Per-environment overrides keyed by environment key (e.g. “production”, “staging”). A forwarder delivers in an environment only when environments[env].enabled is true. Each entry may carry an optional HttpConfiguration override; omit it to inherit the base #configuration. Every referenced environment must exist and be managed for the account.

Returns:

  • (Hash{String => ForwarderEnvironment}) —

    Per-environment overrides keyed by environment key (e.g. “production”, “staging”). A forwarder delivers in an environment only when environments[env].enabled is true.

#filter ⇒ Hash?

Returns Optional JSON Logic expression evaluated per event. When set, events that don’t match are recorded as filtered_out deliveries instead of being delivered to the destination.

Returns:

  • (Hash, nil) —

#forward_smplkit_events ⇒ Boolean

Returns When true, this forwarder also receives platform change events that smplkit records about your own resources (flag, configuration, and similar changes). Each such event is delivered through every environment this forwarder is enabled in, using that environment’s resolved configuration. Defaults to false — platform change events are not forwarded unless you opt in. Independent of the per-environment enabled settings, since platform change events are not tied to a deployment environment.

#transform ⇒ Object?

Returns Optional template applied to each event before delivery. Free-form — the audit service passes the value verbatim to the engine named by #transform_type. For TransformType::JSONATA a JSONata expression string; nil delivers the event JSON as-is. Must be paired with a non-nil #transform_type.

.validate_transform_pair!(transform, transform_type) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Validate the (transform, transform_type) pair.

Both must be nil or both must be set. When transform_type is TransformType::JSONATA, transform must be a String (the JSONata expression). Other engines accept any value.

Raises:

  • (ArgumentError)

end

#_environment_override(environment) ⇒ Object

Return the override for environment, creating an empty one if absent.

The per-environment mutators reach through here so an existing override’s other field is preserved when only one of enabled / configuration is being set.

def _environment_override(environment)

Soft-delete this forwarder on the server.

def delete

  @client.delete(@id)
end

#save ⇒ self Also known as: save!

Create or update this forwarder on the server.

Upsert behavior is driven by #created_at: a forwarder with no created_at is created (POST); otherwise it’s full-replace updated (PUT). After the call, every field is refreshed from the server response (including newly-assigned id, created_at, updated_at, version).

Returns:

  • (self)

end

#set_configuration(configuration, environment: nil) ⇒ Object

Set this forwarder’s destination configuration in memory.

With environment omitted, replaces the base #configuration. With environment given, sets the per-environment override’s configuration on #environments, creating the override entry if it doesn’t exist yet (preserving any already-set enabled on it). Call #save to persist.

  else
    _environment_override(environment).configuration = configuration
  end
end

#set_enabled(enabled, environment: nil) ⇒ Object

Set this forwarder’s enablement in memory.

With environment omitted, sets the base #enabled (which the server pins false regardless — enablement is per-environment). With environment given, sets the per-environment override’s enabled on #environments, creating the override entry if it doesn’t exist yet (preserving any already-set configuration on it). Call #save to persist.
