New question #191085 on Graphite:
https://answers.launchpad.net/graphite/+question/191085
Hi,
I have recently begun to use Graphite . I have used the default example_client.py and that data is generated and I can view it. However, we have quite a bit of data that was collected since Jan and we are trying to retrofit the data. We have defined the following kinds of values in storage-schemas.conf
[carbon]
pattern = ^carbon\.
retentions = 60s:120d
[other_data]
pattern = ^Test\.
priority = 100
retentions = 60:43200,1800:17520
[default_1min_for_1day]
pattern = .*
retentions = 60s:1d,1800s:90d
I wrote up a script to transfer data to this . Initially the listener.log showed me errors :19/03/2012 14:27:49 :: invalid line received from client 10.0.1.2:45212, ignoring . Fixed that bit . Then started the carbon-cache via the debug mode and I can see stuff being written to the disk in the front end :
19/03/2012 16:06:22 :: [console] Sorted 1 cache queues in 0.000018 seconds
19/03/2012 16:06:22 :: [updates] wrote 47 datapoints for Test.Data in 0.00154 seconds
19/03/2012 16:06:22 :: [listener] MetricLineReceiver connection with 10.0.1.2:33402 established
19/03/2012 16:06:22 :: [listener] MetricLineReceiver connection with 10.0.1.2:33402 closed cleanly
When I choose the range in the front end , I can only see the timeline being shown but no data is displayed. The web log at times shows me things like:
storage/log/webapp/error.log <==
storage/log/webapp/error.log <==

Mon Mar 19 01:35:04 2012 :: Exception Caught
Traceback (most recent call last):

len_prefix = recv_exactly(conn, 4)
File "/opt/graphite/webapp/graphite/render/datalib.py", line 188, in recv_exactly
raise Exception("Connection lost")
Exception: Connection lost
Can you point me as to where I am going wrong ? The storage folder is owned by the apache user. We are running Graphite on Centos and followed the instructions on the Graphite website.
Thanks
Ranjan
