Are servers shutting down or booting up without your knowledge something that often happens to you?

You know，sometimes Vps can go offline because Provider's maintanices or outages.So I want to monitor these events and record them~

What's wrong with the plethora of uptime monitors that have been mentioned here? Why do you want to roll your own? Wheel is round. Must reinvent. Ooga booga?

Is HetrixTools not enough?

(edit) I mean, what I said about their API

...check the uptime?

I use Munin, you can notice if the server has been rebooted using the uptime graph.

A simpler solution would be to send a mail from the host at init.

Sir, you are needing AutoBoot(tm) from DewLancing sir.

Write a systemd service that is configured to start automatically.
You should use Type=oneshot.
Then, put two different commands in ExecStart= and ExecStop=, the former is called when your server is booting, the latter is called when your server is shutting down.
