Is your feature request related to a problem? Please describe.

I want to add pod labels to some metric。But I can not finish this easily。for example when I get some metric about pod by intermediary system。

Describe the solution you'd like

we can add sources.from a enum metric_attribute to match data point's attribute and then fetch pod labels。

Describe alternatives you've considered

@halleystar I think your need would be better served by the transformprocessor, have you looked into that processor yet? It can add resource attributes based on datapoint attributes.

[TylerHelmuth]

Or are you saying the pod association would come from a datapoint attribute instead of a resource attribute?

[halleystar]

Thank you for your reply. I have learned about transformprocessor, but it does not seem to meet my needs. The transformprocessor requires all attributes to exist in source_attribute or data_points, but for the metrics of the pod obtained from the intermediary service, the pod-related label attribute does not exist. Need to be obtained from the pod.

[TylerHelmuth]

@halleystar is your goal to do pod association using a datapoint attribute or to add pod labels to only some metrics?

[halleystar]

yeah, do pod association using a datapoint attribute

[TylerHelmuth]

I don't think that would be impossible, but would be very tricky as not all the datapoints in a payload would be guaranteed to have the same value. How would the association work if there are 2 datapoints that have different attribute values?

In the meantime you can solve your problem using a transformprocessor before the k8sattributesprocessor to set a resource attribute using a datapoint attribute

set(resource.attributes["test"], attributes["test"])
