[rrd-users] R: AW: R: Export values from RRD, possible?

[Simone Felici - Alpikom Spa]

Yes ;)

rrdtool info test.rrd
[...]
rrd_version = "0001"
step = 300
last_update = 1074507618
ds[eth0_in].type = "COUNTER"
ds[eth0_in].minimal_heartbeat = 600
ds[eth0_in].min = NaN
ds[eth0_in].max = NaN
ds[eth0_in].last_ds = "1844871780"
ds[eth0_in].value = 1.5333594219e+07
ds[eth0_in].unknown_sec = 0
ds[eth0_out].type = "COUNTER"
[...]

Serge already said I've to add an "-" after rrdtool graph:

After this modify no errors, ok, but no stdout too, also the command will
execute without problems and without any output, nothing!


[root at test sbin]# rrdtool graph - -s -36800
"DEF:eth0_in=test.rrd:eth0_in:AVERAGE" PRINT:eth0_in:AVERAGE:"%7.2lf %Sb/s"
[root at test sbin]#

:(
