[rrd-users] Unable to print date to the graph

[Emre Aydın]

I'm not sure why you're using GPRINT.
I add the date to my graphs too in my bash script. But I add it as a
COMMENT. Here's the basic idea.

time_readible=$(echo $(date) | sed 's/\:/\\:/g')

COMMENT:"Last Update: $time_readible"

the sed line is just to add a backslash before every semi-colon (so that
rrdtool won't think of it as a command like it happened earlier to you)

Hope this helps,
