红帽全球峰会12.10. 跟踪 SSSD 后端中的客户端请求
SSSD 异步处理请求，并将来自不同请求的消息添加到同一日志文件中。要在后端日志中跟踪客户端请求，您可以使用唯一的请求标识符 RID" <integer> 和客户端 ID '[CID # <integer>]。这些标识符有助于隔离日志，以遵循跨多个 SSSD 组件的日志文件从头到尾的请求。
先决条件
- 您已启用了调试日志，并且已从 IdM 客户端提交了请求。
-
您有
root特权。
流程
要查看 SSSD 日志文件，请使用
less工具打开日志文件/var/log/sssd/sssd_<domain_name>.log。例如：less /var/log/sssd/sssd_example.com.log
[root@server ~]# less /var/log/sssd/sssd_example.com.logCopy to Clipboard Copied! Toggle word wrap Toggle overflow 查看 SSSD 日志，以获取有关客户端请求的信息。

Toggle word wrap Toggle overflow SSSD 日志文件中的这个示例输出显示了两个不同的请求的唯一标识符
RID#3和RID#4。
但是，对 SSSD 客户端接口的单一客户端请求通常会在后端触发多个请求，因此客户端请求和后端中的请求之间不是 1 到 1 的对应关系。虽然后端中的多个请求有不同的 RID 号，但每个初始后端请求都包括唯一的客户端 ID，以便管理员可以跟踪单个客户端请求的多个 RID 号。
以下示例显示了一个客户端请求 [sssd.nss CID #1] 和多个在后端生成的请求，[RID#5] 到 [RID#13]:
