日志中 sftp 用户的唯一 ID

我在 /var/log/auth.log 中记录 SFTP 行为。输出看起来像这样

May 27 05:58:16 test-server sshd[20044]: User child is on pid 20049
May 27 05:58:16 test-server sshd[20049]: subsystem request for sftp by user test-user

但是，新会话的 ID 总是会发生变化。是否有可能为每个用户的每个会话拥有相同的 ID？例如，用户“child”将拥有他所有的会话 ID 20050。

我正在寻找这个或类似的解决方案，以便我可以将其解析到我的系统并记录用户行为。
