Re: Issue with using use-gprint option.

Hi 

Upon further debug I came to know that the timestamp which is getting
printed as "last updated at" in the graph is causing this error.

These are the debug logs captured in the http error_log which pointed
out me this issue ..

 

Unable to create graph: Garbage ':10:02 2006"' after command:, referer:
http://10.237.2.50/cricket/grapher.cgi?target=%2FMpls-Links%2F10.70.12.2
32_fastethernet2_0;view=Octets

 

 

The Garbage value reported was actually the last updated time stamp
which is getting printed in the graph.

Im not sure whether the colon character in the date timestamp is causing
this error. Hence I just used a transliteration operation on the
variable which holds the last updated timestamp and converted the ":" to
"-". Now im properly getting the graph generated with GPRINT statements
embedded in the graph.

Added the transliteration operation on the variable $lasttime before the
"push @gprints statement' and removed the comma, character in that line.

Now the lines looks like this...

 

$lasttime =~ tr/:/-/;

push @gprints, "COMMENT:\\s", "COMMENT: Last Update at $now_day";

 

Not sure whether this is the correct approach, however this had resolved
the issue I was facing.

Subject: Issue with using use-gprint option.

 

Hi,

 

Im using cricket version 1.0.5 in linux.

RRDTOOL version 1.2.15 .

 

I would like to set the use-gprint option so that i can get the summary
values plotted in the graph itself.

However When "use-gprint" option is set to "true" im not getting the
graph plotted. Getting "Failed to draw graph error".

 

After turning on debug in grapher.cgi following is the log available
from apache error_log.
