How to detect restart of the app by Forever module

Question

I have an application with cluster and Forever. I want to save information from workers before shutdown or restart of the app. So I use process.on('SIGINT') and that works fine for CTRL+C.

But I have stuck with Forever. Is it possible to detect somehow the app was restarted by Forever? Is there any signal about that?

Answer 1

This issue is quite old, but for those who did not saw it, the lastest forever versions support --killSignal (this has been added in dec 2013) so you can use by example --killSignal=SIGUSR2 and catch this signal with process.on('SIGUSR2', func)
