[rrd-users] problem with update (integer values)

[Rogério Schneider]

Hi people.
I have this problem: When I insert (update) an rrd db with my scripts I
insert some int values, but with fetch I read only float value.
But, this is ok if the round turns back into int values, but it is not
really what occurs. When I insert, for example, value 514 I got 356 into the
rrd file !!! I don't know why this is happing, and I need your help.

It is not all times this occurs, but it is very frequent to insert something
linke a 2000 and fetch from rrd values like 1700.. This is bad for me.

I Insert values at each 300 seconds, near, of course, this can vary 60
seconds to more, like, from 300 do 360 seconds each update.

This values make no sense for me, I got, for example, 98 besides the 78 I
puted into rrd, in the second value, just before the 150.


Thanks for your help!
