chrismd proposed the following answer:
Glad to help. If you want to search or navigate the metric hierarchy
(especially when you have a clustered setup) you could do it locally on
the graphite server by using the graphite.storage module (I really need
to document this API, so here's a first stab at it).
bash$ export PYTHONPATH=/opt/graphite/webapp
bash$ export DJANGO_SETTINGS_MODULE=graphite.settings
bash$ python
>>> from django.conf import settings
>>> import time
>>> for metric in settings.STORE.find("servers.*.cpuUsage"):
... print metric.metric_path # servers.foo.cpuUsage
... print metric.fs_path #
/opt/graphite/storage/whisper/servers/foo/cpuUsage.wsp
... print metric.name # cpuUsage
... print metric.isLeaf() # True, which means we can fetch() data
... (timeInfo, values) metric.fetch(startTime, endTime) # both unix epoch
times
... (start, end, step) = timeInfo
... t = start
... for value in values:
... print time.ctime(), value
... t += step
This will work even in a clustered configuration.
If you need to lookup metrics from a remote machine however there is a
HTTP API as well. Basically you can GET
/metrics/?query=servers.*.cpuUsage&format=pickle (or format=treejson for
a JSON object that can be used by an Ext tree). Hope that helps.
