What is "'service':Off" in chassis.leds on PAN-OS 9.1?

[Mt_103]

Hi,

I found out a new item in 'chassis.leds' on PAN-OS 9.1.
There is not shown on PAN-OS 8.1.
Anyone know what does it mean 'service':Off ?

- v8.1
>show system state filter chassis.leds
Chassis.leds:{'alarm':Off, 'fans':Off, 'ha':Off, 'log':Off, 'status':Green, 'temp':Green, }

- v9.1
>show system state filter chassis.leds
Chassis.leds:{'alarm':Off, 'fans':Off, 'ha':Off, 'log':Off, 'service':Off, 'status':Green, 'temp':Green, }

Thank you.

It seems to me to be related to " show system software status" to have an alarm led if a service is not running but it will be nice someone from Palo Alto confirm this as there is no documentation for it.
