ShortLegend

[bocasman]

Hi,

I was wondering if it is possible to set some type of ShortLegend as you do on mrtg, like say, if I'm plotting Temperature set a ShortLegend ºC, then the units string used for Max, Average and Current should be something like:

Current: 25ºC Average: 15ºC Maximun: 41ºC

Good question.

I always thought it could be done using the '--unit' option in rrdtool. Therefore I implimented this option in cacti as well. Of course, I cannot get the values to show up on the graph like the documentation says they should.

Does anyone else know how to even do this in rrdtool?

Hi,

Any one, have an idea for this?

Hi Ian,

After some research I think I have a solution for the ShortLegend issue.

The solution could be to add a field, that could be call ShortLegend or something like that for the GPRINT, and whatever we put in there should appears beside the %s, as it ºC is on this sample code.

Code: Select all

/usr/local/rrdtool/bin/rrdtool graph - \
--imgformat=PNG \
--start="-86400" \
--title="Core Router Temperature" \
--base=1000 \
--height=150 \
--width=500 \
--alt-autoscale \
--vertical-label="celcius degrees (ºC)" \
DEF:a="/usr/local/apache/htdocs/test/cacti/rra/core_temp_inlet.rrd":core_temp_inlet:AVERAGE \
DEF:b="/usr/local/apache/htdocs/test/cacti/rra/core_temp_outlet.rrd":core_temp_outlet:AVERAGE \
AREA:b#007283:"Outlet Temp" \
GPRINT:b:LAST:"Current\:%8.2lf %sºC" \
GPRINT:b:AVERAGE:"Average\:%8.2lf %sºC" \
GPRINT:b:MAX:"Maximun\:%8.2lf %sºC\n" \
AREA:a#00CF00:"Inlet Temp" \
GPRINT:a:LAST:" Current\:%8.2lf %sºC" \
GPRINT:a:AVERAGE:"Average\:%8.2lf %sºC" \
GPRINT:a:MAX:"Maximun\:%8.2lf %sºC\n"
