# S3LoggingConfiguration
Configuration for S3 logging behavior in EMR clusters. Defines how different types of logs are uploaded to S3 based on the specified upload policies for each log type.
## Contents
** LogTypeUploadPolicy **
A map that specifies the upload policy for each log type. The key is the log type, and the value is the upload policy.
Valid log types:
+ `system-logs`: EMR Daemon logs.
+ `application-logs`: Framework logs from Hadoop, Spark, Hive and other applications running on the cluster.
+ `persistent-ui-logs`: Logs required for persistent application UIs such as Spark History Server and Tez UI.
Valid upload policies:
+ `emr-managed`: Standard behavior. Logs are uploaded to S3 bucket as configured in your LogUri, with certain logs retained by the service for operational support and troubleshooting purposes.
+ `on-customer-s3only`: Logs are uploaded only to the customer-specified S3 bucket. This requires you to specify a LogUri when creating the cluster. Persistent-ui-logs cannot have on-customer-s3only policy. Allowed policies for persistent-ui-logs are emr-managed and disabled.
+ `disabled`: No S3 upload for this log type.
Type: String to string map
Valid Keys: `system-logs | application-logs | persistent-ui-logs`
Valid Values: `emr-managed | on-customer-s3only | disabled`
