Description
Hey guys,
I have two measurements, one with static data and one with data that gets updated every minute.
I would like to compare the recent data to the static data and do a math operation on them.
For example:
Static measurement has one field and one tag
Tag: Hostname=A
Field: Value=10
Tag: Hostname=B
Field: Value=5
In the measurement that gets updated every minute I have.
Tag: Hostname=A
Field: Value2=9
Tag: Hostname=B
Field: Value2=4
I would like to use a math operator when Hostnames are the same do Value-Value2 or check if Value == Value2.
Thank you.

First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.

Research direction
The issue names no files, tests, or entry points. First clarify whether Kapacitor should support joining static and updated measurements by the Hostname tag, then identify the relevant processing entry point and tests; completion would require a documented comparison behavior and coverage for both example hosts.
