 | tag\_prefix | Set the tag\_prefix used to validate the tag of logs with k8s resource type. Without this option, the tag of the log must be in format of k8s\_container\(pod/node\).\* in order to use the k8s\_container resource type. Now the tag prefix is configurable by this option \(note the ending dot\). | k8s\_container., k8s\_pod., k8s\_node. |
 | severity\_key | Specify the name of the key from the original record that contains the severity information. |  |

 | resource_labels | An optional list of comma separated strings specifying resource labels plaintext assignments (`new=value`) and/or mappings from an original field in the log entry to a destination field (`destination=$original`). Nested fields and environment variables are also supported using the [record accessor syntax](https://docs.fluentbit.io/manual/administration/configuring-fluent-bit/classic-mode/record-accessor). If configured, *all* resource labels will be assigned using this API only, with the exception of `project_id`. See [Resource Labels](#resource-labels) for more details. | |
