[rrd-users] Re: Printing a text report instead of a graph

[Ruttenberg, Tanya]

I originally thought that would do the trick.  However, I've never
gotten the results I want.

For example, here is my original graph statement

rrdtool graph - \
 --start=end-86400 \
 --title=SSA-SRSW-NCC-W00C02 \
 --vertical-label=bandwidth % \
 --imgformat=PNG \
 --width=750 \
 --base=1000 \
 --height=180 \
 --interlaced \
 
DEF:a=/data1/cricket-data//NCC/ssa-srsw-ncc-w00c02_3-1_if.rrd:ifhcinocte
ts:AVERAGE \
 
DEF:b=/data1/cricket-data//NCC/ssa-srsw-ncc-w00c02_3-1_if.rrd:ifhcoutoct
ets:AVERAGE \
 CDEF:A=a,125000000,/,100,* \
 CDEF:B=b,125000000,/,100,* \
 LINE1:A#00FFFF:ifhcinoctets AVERAGE  \
 GPRINT:A:MIN:"Min\: %8.2lf%s" \
 GPRINT:A:AVERAGE:"Avg\: %8.2lf%s" \
 GPRINT:A:MAX:"Max\: %8.2lf%s" \
 GPRINT:A:LAST:"Last\: %8.2lf%s" \
 LINE1:B#0000FF:ifhcoutoctets AVERAGE \
 GPRINT:B:MIN:"Min\: %8.2lf%s" \
 GPRINT:B:AVERAGE:"Avg\: %8.2lf%s" \
 GPRINT:B:MAX:"Max\: %8.2lf%s" \
 GPRINT:B:LAST:"Last\: %8.2lf%s"

Gives me a nice graph.

I make the following changes removing everything related to the graph
and changing the GPRINTs to PRINTs:

rrdtool graph /var/tmp/out.txt \
 --start=end-86400 \
 
DEF:a=/data1/cricket-data//NCC/ssa-srsw-ncc-w00c02_3-1_if.rrd:ifhcinocte
ts:AVERAGE \
 
DEF:b=/data1/cricket-data//NCC/ssa-srsw-ncc-w00c02_3-1_if.rrd:ifhcoutoct
ets:AVERAGE \
 CDEF:A=a,125000000,/,100,* \
 CDEF:B=b,125000000,/,100,* \
 PRINT:A:MIN:"Min\: %8.2lf%s" \
 PRINT:A:AVERAGE:"Avg\: %8.2lf%s" \
 PRINT:A:MAX:"Max\: %8.2lf%s" \
 PRINT:A:LAST:"Last\: %8.2lf%s" \
 PRINT:B:MIN:"Min\: %8.2lf%s" \
 PRINT:B:AVERAGE:"Avg\: %8.2lf%s"\
 PRINT:B:MAX:"Max\: %8.2lf%s" \
 PRINT:B:LAST:"Last\: %8.2lf%s"

And get what I guess is the expected behavior, but it's not what I want:

Min:   486.93m
Avg:    13.15
Max:    97.81
Last:     2.23
Min:     1.43
Avg:    31.61
Max:    98.62
Last:     2.43

What I want is a list of datapoints that made up the LINE in the graph,
(preferably listed with a timestamp).

P.S.  Have any of you people who *really* understand rrdtool thought
about writing an O'Reilly book about it?

erm... are you saying you want the result of GPRINT, but not in the
graph but rather as text?  If so: use PRINT.
