sysstat包中的sysstat-collect.timer/sysstat-collect.service/sa命令（没有配置文件）

分别相当于systemd-tmpfiles-clean.timer/systemd-tmpfiles-setup.service/systemd-tmpfiles --create      systemd-tmpfiles --remove (这个有配置文件
/usr/lib/tmpfiles.d/*.conf   /run/tmpfiles.d/*.conf  /etc/tmpfiles.d/*.conf)

1. [Unit]
   
2. Description=Daily Cleanup of Temporary Directories
   
3. Documentation=man:tmpfiles.d(5) man:systemd-tmpfiles(8)
   
4. 
   
5. [Timer]
   
6. OnBootSec=15min
   
7. OnUnitActiveSec=1d
