+== Configure data sources 
+
+By default the Infrastructure UI uses the `metricbeat-*` index pattern to query the data. If you configured Metricbeat to export data to a different set of indices, you will need to set `xpack.infra.sources.default.metricAlias` in `config/kibana.yml` to match your index pattern. You can also configure the timestamp field by overriding `xpack.infra.sources.default.fields.timestamp`. See <<infrastructure-ui-settings-kb>> for a complete list.

+By default the Logs UI uses the `filebeat-*` index pattern to query the data. If your logs are located in a different set of indices, you will need to set `xpack.infra.sources.default.logAlias` in `config/kibana.yml` to match your log's index pattern. You can also configure the timestamp field by overriding `xpack.infra.sources.default.fields.timestamp`, by default it is set to `@timestamp`. See <<logs-ui-settings-kb>> for a complete list.
