I don't have a console/shell. It would be nice to get this with the librrd
in Ansi C.
Best regards, Bredi.

but librrd does not format the rrd_fetch output, the formatting is
only done for console output if you are calling the library
functions directly, you get the numbers and you should be all set.

BUT dumping the database shows the same value at the correct last update time. Why is that?

[rrd-users] rrdtool fetch: Where does the 'b' come from?
HI! I'm using the fetch command on the command line with the same start and endtime. I'm getting something like this: b 1250702520: 1.00e+02 What about the 'b' charackter?
