I want to know if is possible to generate and alert (email alert for example) when a service goes down or when user admin turn off any feature especifically when execute "fwaccel off" command.
I'm not sure what you mean by "service" in this context.
In general, there are plenty of ways to monitor the gateway, with Best Practices documented here: Best Practices - Monitoring of Security Gateways and Management Servers running on Gaia OS )
You could easily monitor with your own scripts as well.
Thanks for your answer, I will check the doc.
About "service" I mean CP process for example when FWM or FWD or as I write before when any user execute "fwacell off" for example.
The gateway already monitors (and restarts) several of these processes on it's own.
