error when I change CDEF of graph

Post by joecen »

hi,all

I found an error when I changed the CDEF of a graph.

I created a "none host " and "none graph template" graph in graph management . I added many "graph items" and created a new "CDEF" item with this graph.

this is the code of my graph:

Code: Select all

/opt/rrdtool/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="1_IMGUV_SUM" \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="bits per second" \
DEF:a="/opt/cacti/httpd/htdocs/cacti/rra/traffic_in_31.rrd":traffic_in:AVERAGE \
DEF:b="/opt/cacti/httpd/htdocs/cacti/rra/traffic_in_44.rrd":traffic_in:AVERAGE \
DEF:c="/opt/cacti/httpd/htdocs/cacti/rra/traffic_in_46.rrd":traffic_in:AVERAGE \
DEF:d="/opt/cacti/httpd/htdocs/cacti/rra/traffic_in_45.rrd":traffic_in:AVERAGE \

AREA:cdefd#7EE600:"IMGUV_SUM_INPUT"  \
GPRINT:cdefd:LAST:" Current\:%8.2lf %s"  \
GPRINT:cdefd:MAX:"Max\:%8.2lf %s"  \
GPRINT:cdefd:AVERAGE:"AVERAGE\:%8.2lf %s\n"  \
AREA:e#:""  \

GPRINT:cdefbb:MAX:"MAX\:%8.2lf %s"  \
GPRINT:cdefbb:AVERAGE:"AVERAGE\:%8.2lf %s"  \
AREA:j#:""
I wanna delete a "DEF" in the graph.So I must choose another "CDEF" item with 4 data source.
but the graph couldn't display after I choose the new "CDEF" item.
I saw the code and found the old "CDEF" item still exist.

Code: Select all

/opt/rrdtool/bin/rrdtool graph - \
--imgformat=PNG \

--end=-300 \

GPRINT:cdefbb:LAST:"Current\:%8.2lf %s"  \
GPRINT:cdefbb:MAX:"MAX\:%8.2lf %s"  \
GPRINT:cdefbb:AVERAGE:"AVERAGE\:%8.2lf %s"
my question is:
why the old "CDEF" item still exist?
how to delete the old "CDEF" code on my graph?

Um.... Pretty sure your RPN should not be

Code: Select all

8,a,b,c,d,+,+,+,*
but

Code: Select all

a,b,+,c,+,d,+,8,*
But I could be wrong.



Removing the CDEF, well, edit the graph items and set the CDEF to None, click save.

Um..,I try to edit the graph items and set the CDEF to None.

e'en I delete the item with the CDEF ,the CDEF code still exist .... :evil:

originally code:
