[rrd-users] Difficulty setting Graph TITLE font with RRDs::graph

[Steve Shipway]

This looks as if you have a different version of RRDs to your rrdtool executable version.

 

Try this:

 

                rrdtool  -v

 

This should give you the version of the RRDTool executable, and

 

                perl -MRRDs -e ‘print $RRDs::VERSION;’

 

this should give you the version of your RRDs module.

 

It sounds as if you have an older version of the RRDs libraries installed (possibly v1.2.x).  In this case, reinstall the updated version, or ensure your perl @INC path is pointing first to the newer one.

Subject: [rrd-users] Difficulty setting Graph TITLE font with RRDs::graph

 

Hi list,

I'm having difficulty setting a graph TITLE font size using the RRDTool Perl bindings (RRDs::graph).

When used in a shell with `rrdtool graph`, both "-n TITLE:7:" and "--font TITLE:7:" work as expected and give the desired result.
However, both options when passed to RRDs::graph produce an error.

"-n TITLE:7:" results in: Error: RRDs::graph failed, invalid text property format
"--font TITLE:7:" results in: Error: RRDs::graph failed, unknown option '--font TITLE:7:'

A Google search for both errors hasn't turned up anything useful, the closest I got was a posting in the Cacti forums (http://forums.cacti.net/about28174.html) that suggested upgrading RRDTool.

I am using RRDTool version 1.4.7 on CentOS 5.4

For completeness, I have included below both a dump of the array passed to RRDs::graph which produces the failure, as well as the result of the same arguments passed to `rrdtool graph`

Any advice much appreciated.

Thanks in advance,
Darren
