The Archive component of the WebLogic Diagnostic Framework (WLDF) captures and persists all data events, log records, and metrics collected by WLDF from server instances and applications running on them. You can configure WLDF to archive diagnostic data to a file store or a Java Database Connectivity (JDBC) data source. If you choose to archive diagnostic data to a file store, this file would stored in DOMAIN_NAME/servers/SERVER_NAME/data/store/diagnostics.
Under some conditions, these archived files may grow bigger and bigger and can not be removed automatically if you have not done special configuration. e.g., if JDBC connection profiling is enabled, etc.
