[rrd-users] how to add last update info into graphic?

[John Conner]

hey guys, I am trying to add last update time info into rrdtool graphic,
what I did is something like

#!/bin/bash
now=`date`

rrdtool graph blablabla \
blablabla \
blablabla \
COMMENT:"last update\: $now"

when I ran the scipt, I got the following error,

ERROR: Garbage ':56:46 CDT 2007' after command:
COMMENT:last update\: Wed Jun 20 09:56:46 CDT 2007

I know it was caused by the ":", rrdtool does not like any ":" without "\",

So any quick solution I can print date info on the graphic? thanks a lot!
