Using Graphite, I'm plotting some graph and the same with a time shift.

Eg: 

aliasByNode(my.application.metric.$Continent.$DC.*, 4, 5, 3)
aliasByNode(timeShift(my.application.metric.$Continent.$DC.*, "7d"), 4, 5, 3)

But I'd like to be able to identify the graphs (they currently get the same name).

How to add a prefix or a suffix (or any marker) to a metric alias?

Eg: 

-- EU.PAR.pokemonCaught
-- EU.PAR.pokemonCaught (last week)

Use regex with aliasSub to grab whole ( (.*) ) metric and change it - add desired text ( \1 last week ). E.g. 

aliasByNode(timeShift(my.application.metric.$Continent.$DC.*, "7d"), 4, 5, 3)

should look like

aliasSub(aliasByNode(timeShift(my.application.metric.$Continent.$DC.*, "7d"), 4, 5, 3), "(.*)", "\1 last week")

You could just use alias() to rename it however you like.

  • I cannot, because I have several series (multiple $Continent and multiple $DC). So using a hard-coded alias would hide the Continent and the DC. – Alban Dericbourg Jul 25 '16 at 13:28

    Sorry, brain fart on my part. I was initially going to suggest `aliasSub` but I thought that was overkill lol. – obfuscurity Jul 26 '16 at 13:29
