[rrd-users] Massive difference between "rrdtool graph" and "rrdtool fetch"

[Rick Blundell]

Hello.

I am extracting and summing up a column of values with both tools (graph
and fetch).  The graph sum is 100% accurate but, when I fetch for the
data, and sum it up (including the exponents), the value is very very
low.

If I have an RRD db, and I wish to calculate the total of a specific
column, what is the best way to accomplish this from the command line? 

The command I am using to display all of the rows from the command line
is:

#fetch file.rrd AVERAGE -r 900 -s -604800 -e -300 | tr -s " " | cut -d "
" -f5

This will display all the rows at a 15 minute resolution. I then add up
all of these values and I assume this would be the total, correct?




Thank You,
Rick Blundell
