[Solved]Pango-CRITICAL **: pango_context_load_font:.....

[tonyd]

Hi all,

I'm new to Cacti. I've recently gotten acquainted with it. We have it running on our noc server. The other night it broke due to an Net-SNMP update. So I decided it was probably best to try to replicate/backup Cacti on another server. So I installed Cacti and all of it's dependencies on a new server. I copied over the rra dir and did a dump/restore of the sql, made the necessary changes to the config.php. Cacti is displaying existing data already gathered. But I'm getting these errors in my http-error.log as well as not seeing the graphs update with any new info. I'm not even sure that the snmpgets (or whatever Cacti is using to request it's info - walk, bulk, etc.) are taking place. Here are some lines from the log.

(process:69919): Pango-CRITICAL **: pango_context_load_font: assertion `pango_font_description_get_family (desc) != NULL' failed

(process:69919): Pango-CRITICAL **: pango_context_load_font: assertion `pango_font_description_get_family (desc) != NULL' failed

(process:74373): Pango-CRITICAL **: pango_context_load_font: assertion `pango_font_description_get_family (desc) != NULL' failed
ERROR: invalid y-grid format

My server:
FreeBSD 7
Port tree current, all installed ports to current versions.
cacti-0.8.7b_2
rrdtool-1.3.0_1

EDIT: I've just noticed that Cacti sees only RRDTool v1.2 in the settings interface. However I have 1.3 installed. Also, the Cacti log is empty.

Let me know what other specific ports you may need version info on and I'll supply it. Any help on this would be great. Thanks to all in advance.

EDIT: Still have a problem as noted above, but will start a new thread. Thanks

When you installed RRDTool 1.3 did you properly install Pango-Cairo?

When you installed RRDTool 1.3 did you properly install Pango-Cairo?

The FreeBSD rrdtool port did install cairo/pango last time I used it (a few weeks ago).

rrdtool 1.3 uses a totally different system for fonts (pango), so if your old install used custom fonts or custom font sizes in Cacti, then that might cause the errors you are seeing. Cacti doesn't yet understand 1.3's font stuff.

[tonyd]

I don't fully understand the Cacti installation to be sure. But this is a clean Cacti installation on a separate server. As mentioned, I transferred any graph data (as I understand it) via a dump/restore of the sql and copied the rra dir/files. So how is it that Cacti is using the "old font method"? And how can I change this behavior?

@streaker69:

I don't see a "Pango-Cairo" in my ports tree or on freebsd.org ports. All I see are these:

/usr/ports/graphics/cairo
/usr/ports/graphics/cairo/files/patch-src_cairo-ft-font.c
/usr/ports/graphics/cairo/files/patch-src_cairoint.h
/usr/ports/graphics/cairo-java

I think I may have solved my Pango font error. I configured a default font and fonts for the visual. The "ERROR: invalid y-grid format" still exists. My technical report show this:

Date Tue, 12 Aug 2008 13:54:58 -0600
Cacti Version 0.8.7b
Cacti OS unix
SNMP Version net-snmp
RRDTool Version
ERROR: Installed RRDTool version does not match configured version.
Please visit the Configuration Settings and select the correct RRDTool Utility Version.
Hosts 260

Data Sources Script/Command: 58
SNMP: 2277
SNMP Query: 1457
Script Query: 7

So it's clear that there's a problem with Cacti not understanding that RRDTool v 1.3 is installed. The Settings->RRDTool Utility Version
The version of RRDTool that you have installed. only shows v1.0 and 1.2 as an option.

This is a known error that was already fixed in SVN. Please see upcoming 087c. Until then, use "rrdtool 1.2" setting

Hello, sorry for posting in this topic but I have the same problem.


I use Debian updated to lenny rrd 1.3

And my apache error log is full of this errors.
I searched for the shared libraries of pango and cairo and all of them are installed ( not the dev packages ).

Can you please guide me where to look for the problem.

[stein]

Did you find a solution to this?
I have the same problem with norwegian characters (æøå).

I'm also on Debian Lenny
Rrd 1.3.7
Cacti 0.8.7e

[Gorbachov]

I am still having this problems. I did not manage to get rid of them.

[razvanu]

same problem and here:
debian lenny main
cacti 0.8.7g, rrd 1.3

Code: Select all

(process:19987): Pango-CRITICAL **: pango_context_load_font: assertion `pango_font_description_get_family (desc) != NULL' failed
(process:19989): Pango-CRITICAL **: pango_context_load_font: assertion `pango_font_description_get_family (desc) != NULL' failed
(process:19989): Pango-CRITICAL **: pango_context_load_font: assertion `pango_font_description_get_family (desc) != NULL' failed

anyone ?

[gandalf]

These problems IMHO are related to rrdtool's usage of pango for displaying fonts.
You may use Graph Management, select the graph and use DEBUG to get the plain rrdtool command.
Run that command from cli (redirect output to /dev/null). If the same error shows up, it's an rrdtool issue. Post to e.g. rrdtool-users mailing list
