Monitor server status and receive an email if one of the cores goes down

Recommended Posts

This is a pretty simple tutorial in which I'll show you how to get notified via email (or sms, but this feature is not free) when your server goes offline or is not reachable for some reason.

 

I personally suggest and use HetrixTools, which will be also used in this tutorial.

 

Step 1)

First of all, you want to create an account on HetrixTools website.

 

Step 2)

After you have logged in, from the main menu click on Tools -> Uptime montitors.

and then click on Add monitor to add a new server.

Step 3)

A window will pop up. As monitor type select "Ping/Service monitor".

Then fill up the form as follows:

In the "Monitor from" section you have to select 4 locations. Choose them according to the continent where your server is hosted.

For example, my server is hosted in France and I picked these four locations:

Then click on "show advanced settings" and change "Number of tries" to 1 (or 2) and finally click on "Add monitor".

Now you will be notified if your server goes offline and you will have your personal server status page with detailed information :)

There's an even simpler solution if the cores crash: a telegram bot (probably a discord one is fine as well)

I did something like this with a single-line c++ telegram bot:

The code for the game to handle the abort signal is just:

void emergency_sig(int32_t sig)
{
	if (sig == SIGSEGV)
	{
		tgfeed::CrashRpt();
		abort();
	}
}
// somewhere at the top inside int start(int argc, char **argv)
signal(SIGSEGV, emergency_sig);

in game/src/main.cpp

From HentrixTools you can also get information about memory usage, cpu  usage, network usage etc... and log them (but you have to configure a php deamon for freebsd, however instructions are on hentrixtools website :P )

 

So you can also monitor server resources usage which is nice :)
