Ilias;

I think that if rrd has been created then data were accepted. I'm not sure about rrdtool itself how/if this keeps only single value.

What's the problem?

I've been populating the rrd-ma via the Store functionality and I  ... can't find the data I stored.
Just for testing purposes, i let a script send Storerequests with the same data, for "current" timestamps , every 3 minutes all night. Then I passed the key to a SetupDataRequest, and all I've got was "0"...

If you were always sending the same data, the change in data over time would be 0, so it is behaving correctly :)

Exactly. RRD doesn't store actual data (at least those pS is using) but it calculates delta and then stores average bps.

You're probably right, but the thing is that I am supposed to be sending bps - a data rate.

You are supposed to send counter value i.e. number o bits read from your interface.

OK, got that. Thanks!

The store-eps-request.xml is the one that produces NaN. Any ideas?  I get NaN also with store-eps-request2.xml
The first has optional parameter dataSourceType ABSOLUTE and the latter GAUGE.
The both created new rrd files and I let them populate for at least 15 minutes.

The rrdtool info output is :
rrd_version = "0003"
step = 300
last_update = 1191585752
ds[ds].type = "COUNTER"
ds[ds].minimal_heartbeat = 1800
ds[ds].min = 0.0000000000e+00
ds[ds].max = 1.0000000000e+13
ds[ds].last_ds = "U"
ds[ds].value = NaN
ds[ds].unknown_sec = 152
.
.
.
