How exactly do I write a selector that requests all of the channels that *do
not have a particular label*?
My labels were previously {assetid=<number>, name=<name>}, but I've
recently added *type*, which can be 'cont' (continuous) and 'disc'
(discrete).
This means that I've now duplicated all of my measurement channels, which
is irritating some of my downstream data consumers - I've now got
*Pressure{assetid=5,asset=TransmitterX1223}* and
*Pressure{assetid=5,asset=TransmitterX1223,type=cont}*
What I'd like to do is erase all of my old GTSes, but the only difference
between the ones I want to keep and the ones I want to erase is the *absence
of the 'type' label*.
So basically, I'd like to perform a /DELETE on all channels that don't have
the 'type' label - I've tried a few different styles, such as ~.*{!type} or
~.*{type=null} etc, but had no luck. Is there a syntax I can use?
