这是一个 MongoDB 数据库的认证成功的完整日志记录，其中包含了客户端元数据和认证信息。

客户端元数据记录了客户端的驱动程序信息、操作系统信息和平台信息等。认证信息记录了认证使用的机制、用户名和认证的数据库等信息，还包含了客户端的 IP 地址和端口号等连接信息。此外，该日志记录还包含了一些额外信息，但是由于你没有提供完整的日志内容，我无法确定这些信息的具体内容。

这段日志是一个 MySQL 集群中的一台机器（DONOR）在进行 SST（State Snapshot Transfer）时出现了错误。从日志中可以看到，xtrabackup_checkpoints 文件缺失导致 SST 失败，需要检查 DONOR 日志文件，以找到原因。因为 SST 失败，其他节点（joiner）无法接收状态，集群需要终止。最后，WSREP 进程由于遇到错误而退出。
