no title or legend in graphs

[yardus9]

I searched through the forums and could not find another similar post, sorry if i missed it.

I did a migration of cacti from solaris to centOS, and installed version on the way. Everything seems to be working fine, however, my graphs have no Title or Legends displayed.

I figured this out. You need to have your fonts directory set properly. In this case on CentOS with rrdtool from the dag repository it is:
/usr/share/rrdtool/fonts/DevaVuSansMono-Roman.ttf

Yep, common mistake. And you didn't find it by searching? You may want to use google with special search parm "site:forums.cacti.net". Sometimes, this yields better results.

My friend had the same problem in FC7. Told him to clear out the RRDTool Default Font Path and it was fixed.

Hi,

I have exactly the same problem, since I'm running 0.8.7... strange. I have tested upgrading from 0.8.6j to 0.8.7 or even with a fresh install... same problem. My RRDFontpath is good :
root : fedora - /servers/apache/sites/cacti> ls DejaVuSansMono-Roman.ttf --> OK
RRDFontPath : /servers/apache/sites/cacti/DejaVuSansMono-Roman.ttf

I've also tried setting nothing, setting another ttf (arial). Same Result, my graphs are OK but no legend on my graphs. It seems there's no error in the debug log. Have you another Idea?
PS: RRDtool version 1.2.11 (so I've set 1.2.x in cacti).
Thanx

Hi Gandalf,

It seems to be something like that... you're true!
I've got many :
ERROR: failed to load
ERROR: failed to load
ERROR: failed to load
ERROR: failed to load
ERROR: failed to load .....................
in my apache error.log

Do you have an idea what this could mean?
Thanx by advance

Bye

[gandalf]

If you leave the font out, does it work correctly?
Reinhard

[cornut]

No it seems to be the same...
another idea?

[gandalf]

Please visit Graph Management, select the failing graph. Switch to DEBUG. Post the result

For what it's worth, I'm also experiencing the exact issue as mentionned in the most recent posts, after upgrading from 0.8.6j to 0.8.7.

I've tried specifying a font path, not specifying one, same thing, all the graphs just seem to be missing all the text.

I've tried 2 different ttf files:
/usr/share/fonts/truetype/ttf-dejavu/DejaVuSansMono.ttf
/usr/local/src/rrdtool-1.2.25/src/DejaVuSansMono-Roman.ttf

I've also tried removing all my rrd files so new ones could get created.

In my apache error logs, I'm also getting similar errors, such as:

ERROR: failed to load üUÖ¿
ERROR: failed to load ìí¿
ERROR: failed to load lî¿
ERROR: failed to load ¼dÿ¿
ERROR: failed to load ì$п

And, in my case, a graph debug shows:

RRDTool Command:

/usr/bin/rrdtool graph - \

I found it!!!!

It was because of rrdtool version!
I upgraded from rrdtool-1.2.11 -> rrdtool-1.2.25 and it roxxxxxx!

cacti 0.8.7 needs probably things included in recents rrdtools that cacti 0.8.6x didn't need...
Tell me if it works for you

and thanx very much gandalf

Interesting...

Installing and using rrdtool 1.2.25 has also fixed the problem for me. I do wonder what exactly has changed though.

0.8.7 also is working fine for me on another machine which is using rrdtool 1.2.23.

Perhaps 0.8.7 needs a minimum rrdtool 1.2.x version? Might be something to change in the documentation, is that's in fact the case?

Thanks for the tip cornut.

1.2.25. Wow, downloading in a few minutes
