Hi,
After recreating whisper databases I can see some of the graphs. Now I have another problém - not all statistics are collected! I checked graphite and it displays only few of them. The nav systém have ran for a day now, so I would expect, that it is enough time to collect all informations.
In the screenshot (made from graphite webinterface) you can see various collected statistics - they are not even the same for various ports.
There are no problems reported for this device in the ipdevpoll.log
Any ideas?
Thanks
Mat

Hi,
I'm stupid. I forget to update etc/graphite/storage-schemas.conf and etc/graphite/storage-aggregation.conf.
I deleted all whisper databases and hopefully it will be much better now.

Hi,
Regarding the bug - I'm using 4.0b5 right now. Is the patch also applicable for this version?
Restarting ipdevpoll does help, but not for the first time. I had to restart
it repeatadly (I did it due to other errors and then I mention, that it corrected it)
Regarding the graphs I think there is some problem with graphing/storing data? I attached three pictures: Ten correct.png ... correct graph from rrdtools Ten graphite.png ... graph collected from graphite web interface Ten nav.png ... graph collected from nav interface
It seems to me, that graphite stores too few datapoints, I tried to dump raw
data and I get this:

Shouldn't I set up scheme for carbon database to await only 5 min collections? It seems to me, that after applying derivative function it show nothing due to empty datapoints.

Great!
Now I have these issues:
- graphs showing throughput - there are only empty graphs on port info
tabs. I think that backend should be fine, because I can see some graphs (for example SystemMetrics/CPU are all fine) Maybe it is related to a fetch error from statistics pane. (see screenshot)
See below.
2014-03-24 04:59:09,673 [WARNING plugins.dnsname.dnsname] [inventory IP2] Box dnsname has changed from u 'IP2' to 'DNS2' When I edit device it gets the right name, but it keep reporting only IP. This started when I added unknown device and now I corrected it. So I have other devices with right DNS names as sysnames.
We think this may be related to this bug: https://bugs.launchpad.net/nav/+bug/1292513 . This has been fixed and will be part of the next release.
The port statistics are probably being stored using the IP-address not the DNS name of the IP Device. You can verify this by browsing the Graphite Web interface and see which nodes are present under nav.devices.
Try restarting ipdevpoll. This may fix your current problem.
- how can I change the look of graphs? I'm getting black backgrounded
graphs which are really ugly on white background.
In the graphite configuration directory (perhaps /opt/graphite/conf), copy the file graphTemplates.conf.example to graphTemplates.conf. Then edit it and add the following:
[nav] background = white foreground = black
The work done is really amazing. I look forward when I have it finally fully up.
Thank you! :)
