For some reason, the username of the user calling a command with sudo is not shown in the system log:
$ journalctl -ef
sudo[30160]: pam_unix(sudo:session): session opened for user root by (uid=0)
sudo[30160]: pam_unix(sudo:session): session closed for user root
I assume that the log message should actually be something like session opened for user root by myusername. It doesn't matter whether the sudo caller is a daemon process like telegraf or an interactive user via ssh.
How can I fix this? As it is, its impossible to see who actually called sudo by only checking the log files.
