Problems with RRD Graphs

[Andy_Burn]

I'm running Domotiga on Linux Mint 64-bit edition on a dual core Atom board, so far so good.
I cannot get the graphs working at all.
I installed RRDtool and changed permissions to 777 for the whole DomotiGa directory. I set up the devices and graphs option to collect data, but no joy.
Has anyone seen this and fixed it?
Pleae help

Thanks,
Andy

Andy,
are you trying to produce your own graphs or the simple graphs?
Simple graphs: in the device setup ... x log RRD data / x Enable simple graphing, declare it as belonging to the climate group -> go to the climate tab and you should see your simple graphs. So far I didn't try to go further. But at least you will identify if RRD is working or not

And enable rrdtool debug and watch debug log window for a few minutes.

Hey Vdoucet/Ron
I tried both!
Heres an example from my log file

Code: Select all

But no graphs!!

Fixed it! ...Well nearly!
The clue was in the path name.
In the logs it was looking for "/home/zippy/rrd"
I moved the rrd folder from "/home/zippy/domotiga" into "/home/zippy" and I can see graphs!
Is there a place where I can change the path to restore the folder to its proper place?

p.s. which datasource type is best? gauge? My graph units and axes look strange. Please see the attachment.

Kind Regards,
Andy

[Andy_Burn]

Well, it looks like I got it solved.
I disables quick graphs, set up the advanced ones and all is well with units etc.
Thanks for the help guys.
I'm addicted now!

Strange as the base path is determined automatically, so there is no need to set/change it normally, do the logs turn up in /home/zippy/domotiga/logs ?

Ron,
No, I had to create a folder "/home/zippy/logs" to collect them. This is recent since I did have older logs. When I click 'view file' button, the filename is now "main-2010-12.log (~/logs)" in gedit. This would suggest its got the path wrong. I might just back up my database again and re-install to see what happens. It may be because I moved it between machines? I set it up originally on my main desktop, before transferring to a low power Atom machine.
Would it be possible to state/change the path manually in settings or conf somewhere?
Thanks,
Andy

[RDNZL]

Path is not in db, but foundby code at runtime you see it in startup log.

Will check code but this is first time i see this. Are permissions of domotiga dir ok?

[Andy_Burn]

I found the reason.
I had a copy of the domotiga.conf on my home directory /home/zippy
When it is removed, DomotiGa correctly looks for log and rrd folders in /home/zippy/domotiga
I moved the folders back to the correct position, and it still works. The main logs now give the correct path.
I guess wherever it finds a copy of the file, it uses that as the main path.

Thanks,
Andy
