+The ServiceNow Metrics output data format (serializer) outputs metrics in the [ServiceNow Operational Intelligence format](https://docs.servicenow.com/bundle/kingston-it-operations-management/page/product/event-management/reference/mid-POST-metrics.html).
 
 It can be used to write to a file using the File output plugin, or for sending metrics to a MID Server with Enable REST endpoint activated using the standard telegraf HTTP output.
 If you're using the HTTP output plugin, this serializer knows how to batch the metrics so you don't end up with an HTTP POST per metric.
