You might be interested to use some of the Linaro LAVA (advanced 
validation architecture) components to make your life easier.

In particular we supply the following pieces:

1) Well defined document for representing test results, including 
measurements within some hardware and software context.

2) A server side database that can consume such documents

3) Client side tools and python APIs to process and send documents to 
the server side component. Including libraries to probe the "context" 
form a running system (as in what hardware I'm running on and what 
software is installed)

If you wish to learn more feel free to join #linaro on 
and ping me (zyga) or Paul Larson (plars). The LAVA stack is spread 
around a few launchpad projects and is somewhat hard to find but we're 
working on consolidation and I would love to give you hints on how to 
get started.

Best regards
