Hello!
I have a problem with very similar to this one:
http://forums.cacti.net/about8389.html

All the graphs in cacti are with missing labels. I am using cacti 0.8.7b-2 (Debian package). Everything was working fine before i upgraded the following packages:

[UPGRADE] apache2 2.2.3-4+etch4 -> 2.2.3-4+etch5
[UPGRADE] apache2-mpm-prefork 2.2.3-4+etch4 -> 2.2.3-4+etch5
[UPGRADE] apache2-utils 2.2.3-4+etch4 -> 2.2.3-4+etch5
[UPGRADE] apache2.2-common 2.2.3-4+etch4 -> 2.2.3-4+etch5
[UPGRADE] libfreetype6 2.3.6-1 -> 2.3.7-1
[UPGRADE] librrd2 1.2.27-2+b1 -> 1.2.28-1
[UPGRADE] librrds-perl 1.2.27-2+b1 -> 1.2.28-1
[UPGRADE] rrdtool 1.2.27-2+b1 -> 1.2.28-1

I enabled some debug to catch the command used for creating the PNGs:
it was:
Code:
/usr/bin/rrdtool graph -  --imgformat=PNG  --start=-2678400  --end=-7200  --title="Localhost - Traffic - |query_ifName|"  --rigid  --base=1000  --height=120  --width=500  --alt-autoscale-max  --lower-limit=0  --vertical-label="bits per second"  --slope-mode  --font TITLE:12:  --font AXIS:8:  --font LEGEND:10:  --font UNIT:8:  DEF:a="/var/lib/cacti/rra/localhost_traffic_in_669.rrd":traffic_in:AVERAGE  DEF:b="/var/lib/cacti/rra/localhost_traffic_in_669.rrd":traffic_in:MAX  DEF:c="/var/lib/cacti/rra/localhost_traffic_in_669.rrd":traffic_out:AVERAGE  DEF:d="/var/lib/cacti/rra/localhost_traffic_in_669.rrd":traffic_out:MAX  CDEF:cdefa=a,8,*  CDEF:cdefd=b,8,*  CDEF:cdefe=c,8,*  CDEF:cdefh=d,8,*  AREA:cdefa#00CF00FF:"Inbound"   GPRINT:cdefa:LAST:" Current\:%8.2lf %s"   GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s"   GPRINT:cdefd:MAX:"Maximum\:%8.2lf %s\n"   LINE1:cdefe#002A97FF:"Outbound"   GPRINT:cdefe:LAST:"Current\:%8.2lf %s"   GPRINT:cdefe:AVERAGE:"Average\:%8.2lf %s"   GPRINT:cdefh:MAX:"Maximum\:%8.2lf %s"


When i ran it manually it displayed:
Code:
ERROR: failed to load

and the generated PNG was with missing labels exactly as in cacti.

I ran the same command again but removed all the --font parameters and the generated PNG was with correct labels.

It seems that it isnt loading the font or the parameters are incorrect. (i'm not RRD expert)

Tried setting the RRDTool Default Font Path to some ttf font but without result. The labels still missing.

Any suggestions how to fix it? Thanks in advance!

Hi,

I have exactly the same problem since last update of rrdtool on my Lenny installation.
I do not think it is related to apache update.

I have created a new graph, but still have the problem.
Perhaps a cacti problem with the new version of rrdtool ?

downgrading librrd2 back to version 1.2.27-2+b1 fixed the problem...

I tried rolling back the librrd2, but seeing same problem, not sure if it's the same as posted or not so putting up a screenshot.

I've tried the font path, checked debug, no errors, it seems to be polling, collecting, and graphing the data itself just fine, but no labels.

This is running 0.8.7b on linux (debian testing), across numerous hosts, and numerous graph templates. I've deleted everything and started over twice.

Any one else have some suggestions?

I had the same issue, downgrading both librrd2 and rrdtool to 1.2.15-0.3 solved the issue.

Hallo,

as I ran in the same problem today, I installed the old version of both
librrd2 and rrdtool. This fixed the graphs.

I did a little bit of resaerch an have found a message on debian.org
reporting the same issue.

The guy who reported this, said also that he has solved the problem
with some additional parameters.
Maybe this is interesting for cacti devolopment?

kind regards
