Weathermap working, but graphs gone

[mellowd]

Hi all.

I'm using Cacti 0.8.8a with the weathermap plugin.

The wethermap is working fine, when I hover over a link it shows the the graph. However when I click on the like I don't see any graphs. In fact I don't see any graphs even when browsing the graph tree.

But when I create a NEW link, the graph shows just fine.

A quick example when I'm browsing the graph tree is in the image attached.

If I click on graph properties I see this

Code: Select all

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=1340715595 \
--end=1340801995 \

They used to be there a while ago. I don't remember changing anything

just to add, some even more odd behaviour. If I show 'Tree' view I don't see graphs. If I click 'Preview' view, I see the graphs

Any ideas?

This seems like a Cacti issue rather than a Weathermap one. It sounds like the poller is updating the rrd files correctly (or Weathermap wouldn't get data), but Weathermap doesn't do anything with the graph drawing process.

Hmm. I actually wanted to put this in the main board. Can a mod please move the thread into the correct section? Or do I just post a new thread?

[mellowd]

Can a mod assist?

[Howie]

Just remembered I'm a mod nowadays

Moved to Help: General.

So basically I still have this problem. Anyone got any ideas? I did mention weathermap but that's only because that plugin actually works but my old graphs don't

*bump*

So two questions:

If you paste all that rrdtool command-line into a shell, does it work? (change that first '-' to image.png to get a file output)

Is there anything in cacti.log or the apache error_log?

[mellowd]

Hi Howie.

There are no errors in the cacti.log file. Also there are no errors in the Apache access.log file


I'm not 100% sure what I need to type in via the cli on the server. Can you confirm?

Thanks

[Howie]

(error_log not access.log for apache)

Paste in all of that graph debug rrdtool command line - it's the command that actually generates the graph. But before you do, change the first - to a filename, otherwise it'll try to output a PNG into your console screen (producing garbage).

[mellowd]

Aha.

The error log does show errors:

Code: Select all

ERROR: Could not parse line 'GPRINT::AVERAGE:Average\:%8.2lf %s'
ERROR: Could not parse line 'GPRINT::AVERAGE:Average\:%8.2lf %s'
ERROR: Could not parse line 'GPRINT::AVERAGE:Average\:%8.2lf %s'
ERROR: Could not parse line 'GPRINT::AVERAGE:Average\:%8.2lf %s'

I see all 4 when I refresh the page.

If I paste the rrdtool cli then I get the same error:

Code: Select all

ERROR: Could not parse line 'GPRINT::AVERAGE:Average\:%8.2lf %s'

Any ideas?

The GPRINT error ouccurs e.g. in case no DEF has been set. In Cacti lingo: no valid data source was related to the GPRINT
R.
