为了在某些磁盘上生成指标，我设置了systemd.timer + systemd.service
该计时器每 10 秒旋转一次，我想避免每次这个小脚本生成然后成功时我的日记都被垃圾邮件。
日记这样写多行
Jan 04 17:21:31 hostname systemd[1]: personal.service: Succeeded.
-- Subject: Unit succeeded
-- Defined-By: systemd
-- Support: http://www.ubuntu.com/support
--
-- The unit personal.service has successfully entered the 'dead' state.
此外，每次服务启动都会进行审核
