单个服务的正常运行时间

我在生产服务器上运行多个 unicorn 进程。现在我想检查我的服务的单个服务正常运行时间。例如，如果任何 unicorn 进程自动重新启动，它应该开始记录其正常运行时间。通过这种方式，我想计算自上次服务以来的正常运行时间。注意：这里我不是在谈论服务器正常运行时间，可以使用以下命令start/restart/reload 了解服务器正常运行时间。uptime

$ uptime
 19:11:25 up 2 days, 21:28,  1 user,  load average: 0.11, 0.09, 0.11

我想知道单个服务的正常运行时间，例如 nginx 的正常运行时间

有可能通过某种方式知道吗？

监控非常适合这个。

该monit status命令清楚地显示了这些信息：
