Question #175552 on Graphite changed:
https://answers.launchpad.net/graphite/+question/175552

Aaron Sterr proposed the following answer:
Here is my local patch to fix the truncated query problem when using
symlinks in whisper storage:

# diff render/datalib.py.20130325 render/datalib.py
226c226,228
<       cachedResults = CarbonLink.query(dbFile.real_metric)
---
>       # BUG: real_metric (from storage.py) breaks in at least some cases when symlinks are used.
>       #cachedResults = CarbonLink.query(dbFile.real_metric)
>       cachedResults = CarbonLink.query(dbFile.metric_path)


I am not sure if what else this might break.  There was probably a
reason for the code that attempts to resolve symlinks and then use that
result in the cache query.  Caveat Emptor.
