Graph is not renedered because of incorrect parameter

[dma_k]

I have created a graph with tree Data Sources, nothing tricky. However, seems like Cacti generates incorrect RRDTool command:

Code: Select all

RRDTool Command:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="Ping Latencies" \
--base=1000 \
--height=120 \
--width=800 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="" \
--slope-mode \
--font TITLE:10: \
--font AXIS:7: \
--font LEGEND:8: \
--font UNIT:8: \
DEF:a="/var/lib/cacti/rra/hosts_ping.rrd":ping_mail_ru:MAX \
DEF:b="/var/lib/cacti/rra/hosts_ping.rrd":ping_orangle_nl:MAX \
DEF:c="/var/lib/cacti/rra/hosts_ping.rrd":ping_rapidshare_com:MAX \
LINE2:#0000FFFF:"mail.ru" \
GPRINT:a:LAST:"       Last\:%8.2lf %s"  \
GPRINT:a:AVERAGE:"Avg\:%8.2lf %s"  \
GPRINT:a:MAX:"Max\:%8.2lf %s\n"  \
LINE2:#FF0000FF:"orange.nl"  \
GPRINT:b:LAST:"     Last\:%8.2lf %s"  \
GPRINT:b:AVERAGE:"Avg\:%8.2lf %s"  \
GPRINT:b:MAX:"Max\:%8.2lf %s\n"  \
LINE2:#00FF00FF:"rapidshare.com"  \
GPRINT:c:LAST:"Last\:%8.2lf %s"  \
GPRINT:c:AVERAGE:"Avg\:%8.2lf %s"  \
GPRINT:c:MAX:"Max\:%8.2lf %s\n" 

RRDTool Says:

ERROR: parameter '#0000FFFF' does not represent a number in line LINE2:#0000FFFF:mail.ru

When I correct the corresponding lines to:

Code: Select all

LINE2:a#0000FFFF:"mail.ru"  \
LINE2:b#FF0000FF:"orange.nl"  \
LINE2:c#00FF00FF:"rapidshare.com"  \

and execute the command from console, the resulting PNG is perfect. I can't understand, why cacti skips the reference just in one case, and includes it in other cases?

I've found similar cases here and here. The advice to remove and add Data Sources is not perfect, and I have already removed and created new graph.

Additional information:
Cacti Version: 0.8.7b
Cacti OS: unix
RRDTool Version: RRDTool 1.2.x

Maybe you should post screenshots of your graph definition / graph template, global overview and lines definitions pages.
Hopefully someone here will see something...

The LINE graph items are not related to any data source as should be. Please correct the Graph Template accordingly

I have reviewed my Graph Template and found an error in "Graph Item Inputs": The "Associated Graph Items" checkbox was not checked After I raised the flag, that problem went away.

Thank you for feedback!

hello. a similar problem:
When I try to watch graphics, get the error in the httpd.log:
"ERROR: parameter '#00CF00FF' does not represent a number in line AREA:#00CF00FF:In"

Have you tried my advise? If that does not work, then dump your RRD script and graph definition.
