  • username (String) (defaults to: lookup('profile::gnmi_telemetry::username'))
  • password (String) (defaults to: lookup('profile::gnmi_telemetry::password'))
  • targets_sub (Hash[String, Any]) (defaults to: lookup('profile::gnmi_telemetry::targets_sub'))
  • outputs (Hash[String, Any]) (defaults to: lookup('profile::gnmi_telemetry::outputs'))
  • subscriptions (Hash[String, Any]) (defaults to: lookup('profile::gnmi_telemetry::subscriptions'))
  • processors (Hash[String, Any]) (defaults to: lookup('profile::gnmi_telemetry::processors'))
