在Debian系统中，主要通过systemd定时器（timer）进行监控，核心命令如下：
sudo systemctl list-timers --all。sudo systemctl status <timer_name>.timer。sudo journalctl -u <service_name>.service。sudo journalctl -u <service_name>.service -f。sudo systemctl enable/disable <timer_name>.timer。sudo systemctl start/stop <timer_name>.timer。sudo systemctl daemon-reload。sudo systemctl is-enabled <timer_name>.timer。sudo systemctl show --property=NextStartUTC <timer_name>.timer。通过以上命令可全面监控定时器的运行状态、日志及配置，确保任务按预期执行。
