New question #103036 on Graphite:
https://answers.launchpad.net/graphite/+question/103036

I installed graphite on a VM on my desktop.  After some teething issues, and looking at the answers here (the install documentation REALLY needs updating...), everything looks OK.  So I launched the webapp (no data inserted yet) and got a page with a bunch of horizontal lines - it took a LONG time to render.  So I thought, OK, something's working, let's get some data in here.

I set up the carbon-cache daemon (again, documentation needs updating) and wrote a little client to read some data from a CSV file (the data is from a sar output from two hosts that are of interest).  I successfully (at least I think...) inserted 3 different metrics, 7 or 8 points each.

But when I tried to look at the graph, I still get nothing but lines.  

Here is the URL I used:

http://localhost/graphite/render?from=00:00%2011.02.2010+0h&until=01:00%2011.02.2011+0h&target=servers.*&title=PROD01_TEST


Looking at the web access.log, I see things like the following (20 or 30 identical entries):

127.0.0.1 - - [02/Mar/2010:20:38:28 -0600] "GET /graphite/composer/composer/composer/composer/composer/composer/composer/browser/header/composer/? HTTP/1.1" 200 793 "http://localhost/graphite/composer/composer/composer/composer/composer/composer/composer/browser/header/"; "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.8) Gecko/20100214 Ubuntu/9.10 (karmic) Firefox/3.5.8"

And finally:
127.0.0.1 - - [02/Mar/2010:20:38:28 -0600] "GET /graphite/composer/composer/composer/composer/composer/composer/composer/composer/composer/?showTarget=servers.*&title=PROD01_TEST&from=00%3A00+11.02.2010+0h&until=01%3A00+11.02.2011+0h&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&target=servers.%2A HTTP/1.1" 200 876 "http://localhost/graphite/composer/composer/composer/composer/composer/composer/composer/composer/?showTarget=servers.*&until=01%3A00+11.02.2011+0h&from=00%3A00+11.02.2010+0h&target=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&showTarget=servers.%2A&title=PROD01_TEST"; "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.8) Gecko/20100214 Ubuntu/9.10 (karmic) Firefox/3.5.8"

The data I inserted is between 00:00:01 and 00:08:01 on Feb 11th.

So two questions:

1) Regarding the time format, all our servers run on UTC time, but the VM is running on PST (it's my desktop).  Do I have to take that into account?  The data is, of course (and by definition!) UTC.  I did try both local time and UTC time on the URL, but the result was the same.

2) Do these log entries indicate something wrong?  They seem a little strange to me... If not, fine, but if so, what?

Thanks for any advice.
