Re: alarm/severity

[Ralph Lange <Ralph.Lange@bessy.de>]

The current plan (afaik) is to allow even more user-defined "triggers". 
Or "filters". Or "events". (Everyone of us has different interpretations 
of those terms...)
Your last mentioned subscription won't be enough, as e.g. the Alarm 
Hander is also interested in the value, but only wants updates when the 
severity changes.
The trigger/events and channels/fields/views aspects of a connection are 
orthogonal.
