 The default list of resource attributes to store as labels can be configured using `default_resource_attributes_as_index_labels` under the [distributor's otlp_config](https://grafana.com/docs/loki/<LOKI_VERSION>/configure/#distributor). You can set global limits using [limits_config.otlp_config](/docs/loki/<LOKI_VERSION>/configure/#limits_config). If you are using Grafana Cloud, contact support to configure this setting.
