個人服務的正常執行時間

我在生產伺服器上執行多個獨角獸程序。現在我想檢查我的服務的單個服務正常執行時間。例如，如果任何獨角獸程序自動重啟，它應該開始記錄其正常執行時間。通過這種方式，我想計算自上次服務以來服務的正常執行時間start/restart/reload 注意：這裡我不是在談論伺服器正常執行時間，可以通過使用uptime如下命令知道。

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

我想知道單個服務的正常執行時間，比如 nginx 的正常執行時間

有可能以某種方式知道嗎？

Monit非常適合這個。

該monit status命令清楚地顯示了此資訊：
