Hello All,
Q1: How can I obtain the start and end value in the RRD/RRA so that
I can dump all values in the rrd/rra during "start" to "end" time?
Q2: How can I just simply fetch from the start to the ending (or last)
data value in rrd/rra?
I find that the value "start" and "end" cannot be used together or
reference to each other in command like
rrdtool fetch --start --end
e.g.
Hope this can get the "start" and "end" value from the output
> /usr/local/rrdtool-1.0.25/bin/rrdtool fetch etc6p3.rrd AVERAGE
--start start+0s --end end-0s
ERROR: the start time cannot be specified relative to itself
Hope this can get the end value from the command output
> /usr/local/rrdtool-1.0.25/bin/rrdtool fetch etc6p3.rrd AVERAGE
--start end+0s --end end-0s
ERROR: the end time cannot be specified relative to itself
> /usr/local/rrdtool-1.0.25/bin/rrdtool fetch etc6p3.rrd AVERAGE
--start end+0s --end start-0s
ERROR: the start and end times cannot be specified relative to each other
Thanks in advance !
Best Regards,
Alex
