Merge aliasByNode and aliasByMetric in Grafana backed by Graphite

Question

I want to label series by hostname + metric name. I know I can use aliasByNode(1) to do first part and aliasByMetric() to do the second. Any ideas how can I merge those two functions in a single metric?

Answer 1

Something that would solve ALL these problems would just be to have a string with replacement parameters for the metric nodes, like,

aliasByVars("core.app.city.rack.app.instance.thread", 
  "resource: city-$3,rack-$4")

You could intersperse static text with the values of the metric elements (nodes) all you wanted.

That could replace alias, aliasNode, aliasMetric and 99% of aliasSub with one simple, easy to understand namer.

There would be some aliasSub applications where you used partial node names this could not replace.

Answer 2

aliasByNode can take multiple arguments.

aliasByNode(apps.fakesite.web_server_01.counters.requests.count, 2,5)

returns web_server_01.count.

The Grafana query editor for Graphite does not support this but if you toggle edit mode then you can edit the raw query. After editing it, you can toggle back.
