## Options

<definitions>
  <definition term="--service string required">
  </definition>
  <definition term="--error string">
    If provided, the agent configuration will be marked as error and `applied_by_agent` will be set to `false`.
    This is useful for cases where the agent configuration was not applied successfully.
  </definition>
  <definition term="--etag string">
    If etags match then `applied_by_agent` field will be set to `true`
  </definition>
  <definition term="--mark-as-applied-by-agent">
    `markAsAppliedByAgent=true` means "force setting it to true regardless of etag".
    This is needed for Jaeger agent that doesn't have etags
  </definition>
  <definition term="--input-file string">
    path to a JSON file to use as command input
