Recently the beta for rrdtool 1.3 was released. (actual versioning is 1.2.99907080300) - information available here

I went ahead and began playing with it in test and having found no problems; moved it into production.

Combined with the Boost Plugin I found the write process to be about 15-20% faster with 1.3 versus 1.2.23.

Hi

I'm using RRDtool 1.3 beta 1 on a test system, and it works fine (with Cacti 0.8.6k beta 2).

RRDtool 1.3 needs Cairo/Pango for graphing, and does not need TTF fonts anymore (in fact no font is provided).

Graphs look different :

1.2.23
1.3 beta 1

I'll try to play with text alignement today and fonts sizes...

Where/How are you playing with the font size and alignment with rrdtool 1.3? Since the visual tab in cacti is only relevant it seems for 1.2

Hi,

I've also upgraded to rrdtool 1.3 beta and had an alignment problem.

It looked like this:

There was no space between the current counter and "Average" and the average counter and "Maximum" (like with rrdtool 1.2).

I tried to add a trainling space in the GPRINT definition but Mysql was removing it always.
So I read the MySQL docu and found that changing the gprint_text column from VARCHAR to TINYTEXT (or any other TEXT type) keeps trainling spaces and would not need more data type memory.

So I changed column type and added the trailing space:.
Now it looks like I want it:

Perhaps Cacti developers could consider this change of data types.

Best regards,
Johannes

Does anyone have RRDTOOL 1.3 as a windows (exe) binary ? I tried to compile my own using Cygwin, but seem to have failed ! Thanks

Is there any work being done to correct GPRINT alignment for RRDtool 1.3 in Cacti? I'm seeing the mis-aligned GPRINTS text as shown in the 2nd post here on all my graphs.

Just curious before I go about rolling back RRDtool.

FWIW, Fedora Core 8 uses RRDtool 1.3beta1 as part of its distro currently.

Alignment may look weird if not using mono-spaced fonts. Cacti does not yet support new "alignment" codes introduced with latest rrdtool versions

Yeah, I've tried several different fixed width fonts(courier, console-mono, etc) but the results are the same. I guess I'm waiting for an updated Cacti to go along with the new RRDtool.

Please visit such a graph at Graph Management, switch to DEBUg and post a screenshot

Thanks for taking a look! Here you go...

Edit: oops... sorry.. need to redo the screenshot.

Actually in creating the screenshots I noticed something that might be at the root of the problem here. It looks like the new RRDtool has made some changes regarding font usage:

http://oss.oetiker.ch/rrdtool-trac/wiki/RRDtool13

We now use Pango for all text rendering. Pango integrates with Cairo, Freetype and Fontconfig. This has a number of implications:

- Fonts are accessed through the fontconfig interface. This means you get access to all fonts on your system, and at the same time loose the ability to use true type fonts directly.

- All text is passed through Pango Markup. This means it is now possible to switch font properties inside any rrdtool graph text field.

I noticed this as I was making a mockup with 4 different fonts -- nothing ever changed with the font face, just size. So it looks like RRDtool is just looking to do name matching against "installed" fonts now rather then using a given TTF file. The problem is that unless Cacti can find the "font filename" you spec in the visual properties, it won't output anything in the font name area.

Or I could just be loosing it

I've just saw that RRDtool 1.3 was the one shiped with Fedora 8...

Some news

RRDtool 1.3 beta 4 was out this morning, with a lot of bugfixes, including this one :

* fixed: major text alignement bug in rrdtool graph

It builds fine on RHEL5, but RHEL4 needs "pangocairo". Still searching...
