[Q] diffSeries on multiple series comparing to a single serie

[nikobearrr]

I have 3 series which give me their timestamps in milliseconds:

#A: service.abc.timestamp
#B: service.xyz.timestamp
#C: ervice.mno.timestamp

and I would like to compare them with real time. I use

#D: scale(time("now"), 1000)

as a series to get the current time in milliseconds.

What I can do now is specify them 1 by 1 and and do a diffSeries(), e.g.

diffSeries(#A, #D) will give me the service abc vs current time. diffSeries(#B, #D) will give me the service xyz vs current time.

What I would like to do, is do them on bulk. So for series #A I specify service.*.timestamp and then do diffSeries(#A, #D) and get the difference for any service that shows up.

I have tried the above, but that would not do it. As I understand it the diffSeries() compares 2 series and in the above case it combined the wildcard into 1.

My question is if what I would like is achievable and if yes how?

You can try something like

applyByNode(service.*.timestamp,1,"diffSeries(%.timestamp,scale(time("now"), 1000))")
