Monitor the proxy memory usage and automatic restart

Depending on the activity of your proxy and the amount of memory you have allocated to your server, it is possible that the proxy service consumes a significant portion of the available memory.

See: Display history and graphs of your proxy memory usage

Especially when you put Artica Proxy in production, you are not sure of the load-bearing capacity of your proxy with your users.
When the proxy service reaches a critical memory, it will try to survive but will render a random service because it will not be able to load new child processes.
To correct this behavior, Artica v4.30 Service Pack 383 has implemented a memory usage monitor for the proxy service.

If the monitoring daemon detects an excessive proxy service memory usage , it will perform a quick restart of the proxy ( 10 seconds ).
By default, the value of 75% of the server memory is allocated.

To tune this value, on the left menu, go to “Your Proxy” / “Status”
Select the Watchdog tab.

In this example, it means: if the proxy service exceed 75% of the server memory during 5 minutes, then restart the proxy service.

Select the percentage of memory usage of your proxy and the period that the memory exceed.
