[rrd-users] Re: Putting current time in rrdgraph COMMENT

I've successfully placed the current time in a rrdgraph generated png
file in perl, with the following snippet:

    $nowlit = "$mon/$day/$yr $hour:$min:$sec GMT";

    $com = " COMMENT:\"Written: $nowlit\"";


I now have the need to do this directly from a shell file (or rewrite a
bunch of shell scripts to perl)


A current command might be:


rrdtool graph /graphs/w1p1/allin.png -s e-24h -a PNG -w 600 -h 150 -t
"West1  All Inbound Packets"  \

   DEF:disc=/usr/perl/w1p1.rrd:disc:AVERAGE \

   DEF:b=/usr/perl/w1p1.rrd:req:AVERAGE \

   DEF:c=/usr/perl/w1p1.rrd:inf:AVERAGE \

   DEF:d=/usr/perl/w1p1.rrd:decl:AVERAGE  \

   DEF:e=/usr/perl/w1p1.rrd:rel:AVERAGE \

   CDEF:all=disc,b,+,c,+,d,+,e,+ \

   LINE1:disc#FF0000:disc: \

   LINE1:b#00FF00:req: \

   LINE1:c#0000FF:inf: \

   LINE1:d#555555:decl: \

   LINE1:e#550000:rel: \



I just want to add a COMMENT: command that includes a human-readable
timestamp.  I couldn't figure out the exact syntax, even with the
seemingly similar question involving rrdcgi.


Thanks in advance!
