Solved!

So it looks like this is actually a pretty common problem when you can work out what the root problem is.

Digging around, I located the call that renders text on the graphs: imagetext. imagetext is a routine (acutally called imageText - note the uppercase T - which makes it hard to find on cases sensitive searches

) that wraps imagettftext....

more digging results in this wrapper relying on the font file path being:

/usr/share/fonts/dejavu/DejaVuSans.ttf

Do some creative Googling with this, and there are plenty of Zabbix font issues that point you to a fix . It seems many linux distros ship with dejavu-lgc ( which contains only Latin, Greek, Crylic - i assume to save size?) not dejavu (the complete set).

dejavu-lgc installs to:
/usr/share/fonts/dejavu-lgc/DejaVuLGCSans.ttf

So edit /zabbix-web-site/include/defines.inc.php and edit the following lines:

Code:

	define('ZBX_FONTPATH',		'/usr/share/fonts/dejavu-lgc');	// where to search for font (GD > 2.0.18)
	define('ZBX_GRAPH_FONT_NAME',	'DejaVuLGCSans');		// font file name
	define('ZBX_FONT_NAME', 'DejaVuLGCSans');

restart httpd and bingo ... zabbix graphs with text!

Thanks to the Zabbix team for a great product, it's a pleasure to use! If I could suggest a small enhancement:

Can zabbix search the font path during the install wizard and ensure it finds an adequate ttf file?

hey

i have the same problem, missing legend and axes on zabbix graphs.
Zabbix is running on Centos 5.4

i've installed dejavu-lgc, and chanched path at include/defines.inc.php of zabbix web.

But after http restart the problem didnt dissapear. Still no text at legend.
What should i check ?

Further config updates

Yo hippie,

I don't check this forum very often so sorry I hadn't responded to you. But if you're still having this issue I'd be happy to help.

I did notice that the fix above only did half the job, in the same file you have to also update the line:

Code:

define('ZBX_FONT_NAME', 'DejaVuLGCSans');

I'll update the post above to include this.

I'm beginning to think a 'more proper' fix might be to create a link:

Code:

ln /usr/share/fonts/dejavu-lgc/DejaVuLGCSans.ttf /usr/share/fonts/dejavu/DejaVuSans.ttf

Not sure if that's really a legit way to do things, but I think it would work. Perhaps, if an experienced linux admin is reading, they might be able to offer some advice on what they think? Edit the config -or- create a link?

later

I'm having the exact same problem but this wasnt enought for me.

I've changed the font path to my fonts dir to
/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf

but nothing happened.

I'm running Zabbix 1.8.2 from the Debian Squeeze package.
(installed with a simple apt-get install)

Any ideas?

I've find out that my problem was a permission problem. I couldn't see text because the application didn't have permission to access the font files.

Maybe you should try this code and then see what is the error you get. Save this to a file, open in your browser and check the source to see the errors.

It worked for me.

Code:

<?php
// Set the content-type
header('Content-Type: image/png');

// Report all PHP errors (see changelog)
error_reporting(E_ALL);

// Create the image
$im = imagecreatetruecolor(400, 30);

// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);

// The text to draw
$text = 'Testing...';
// Replace path by your own font path
$font = '/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf'; //Change to the location of your font file

// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);

// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>

Hi,

Exactly which file you changed, and this x-th row?

advance, thank you for your help.

**mpax** · 16-06-2014, 20:00

Change font name and ensure path is correct for your environment

I have DejaVu installed rather than DejaVu-lgc and I found that for me I had a slightly different font path and font name. In my case the path was '/usr/share/fonts/truetype/dejavu' and the font name did not include GC, rather it was just 'DejaVuSans'.

So here is what things look like in my situation:
define('ZBX_FONTPATH', '/usr/share/fonts/truetype/dejavu'); // where to search for font (GD > 2.0.18)
define('ZBX_GRAPH_FONT_NAME', 'DejaVuSans'); // font file name
define('ZBX_FONT_NAME', 'DejaVuSans');

Also, I am on Zabbix v 2.2, just as a heads up.

Enjoy!

I have Zabbix server v2.2.4 installed on CentOS 6. Tried to change font location, but text in graphs still missing.

define('ZBX_FONTPATH', '/usr/share/fonts/dejavu'); // where to search for font (GD > 2.0.18)
define('ZBX_GRAPH_FONT_NAME', 'DejaVuSans'); // font file name
define('ZBX_FONT_NAME', 'DejaVuSans');
define('ZBX_GRAPH_LEGEND_HEIGHT', 120);

I've cheked everything, also tried to use DejaVuLGCSans font. Nothing helps, font still missing. Can anyone suggest something else?

Hi all,

I have found the final fix to this problem (this was at me also on Ubuntu server):

1. First, install the needed font.

Code:

# apt-get install ttf-dejavu

2. After that make a symlink about the font into the application (frontend) "fonts" directory

Code:

# ln -s /usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf /usr/share/zabbix/fonts/DejaVuSans.ttf

3. Modify the "ZBX_GRAPH_FONT_NAME" variable in the defines.inc.php (/usr/share/zabbix/include/defines.inc.php) to the following:

Code:

define('ZBX_GRAPH_FONT_NAME',           'DejaVuSans'); // font file name

4. Restart the apache http server:

Code:

# service apache2 restart

Have fun, enjoy!

Cheers,

Blackcode

I had the same issue after upgrade to 4.2.2 and this thread saved my day!

**dolastro** · 01-06-2019, 02:00

Verify permissions for '/usr/share/zabbix/assets', if not 'www-data:www:data':

>chown www-data:www-data assets/

If the file does not exist (/usr/share/zabbix/fonts/graphfont.ttf):

>cd assets/fonts/

Copy the file graphfont.ttf to /usr/share/zabbix/assets/fonts/:

>cp /usr/share/zabbix/fonts/graphfont.ttf /usr/share/zabbix/assets/fonts/

Or link the file:

>ln -s /usr/share/zabbix/fonts/graphfont.ttf /usr/share/zabbix/assets/fonts/

I got this issue, when upgrading Zabbix 4.0 to 4.2.2 on CentOS 7 - this was the solution for me:

Edit
"/usr/share/zabbix/include/defines.inc.php" and change the following lines:

Code:

define('ZBX_FONTPATH', realpath('fonts'));

to

define('ZBX_FONTPATH', '/usr/share/fonts/dejavu');

AND

Code:

define('ZBX_GRAPH_FONT_NAME',           'graphfont'); // font file name

TO

define('ZBX_GRAPH_FONT_NAME',           'DejaVuSans'); // font file name

restart httpd service:
"systemctl restart httpd.service"
