New question #152851 on Graphite:
https://answers.launchpad.net/graphite/+question/152851

I've recently set up graphite (along with StatsD) to track my application. It seems pretty neat, however I'm running into one issue that I can't get past.

When I try to view a graph for a stat that I've incremented, I'm occasionally getting a ValueError when the image gets generated - leading to a broken image. If I try to view the image itself, I receive the following traceback:

Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/django/core/handlers/base.py", line 92, in get_response
    response = callback(request, *callback_args, **callback_kwargs)
  File "/opt/graphite/webapp/graphite/render/views.py", line 143, in renderView
    image = doImageRender(requestOptions['graphClass'], graphOptions)
  File "/opt/graphite/webapp/graphite/render/views.py", line 302, in doImageRender
    img = graphClass(**graphOptions)
  File "/opt/graphite/webapp/graphite/render/glyph.py", line 150, in __init__
    self.drawGraph(**params)
  File "/opt/graphite/webapp/graphite/render/glyph.py", line 392, in drawGraph
    self.setupYAxis()
  File "/opt/graphite/webapp/graphite/render/glyph.py", line 598, in setupYAxis
    order = math.log10(yVariance)
ValueError: math domain error

I can't quite figure out what could be causing this. Anyone have any thoughts here? Thanks!
