[rrd-users] Last value always nan

[Michael Jürgens]

Hi,

I´m using mrtg to collect data and rrdtool to create graphs.
I´m now trying to fetch the last value from datasource and always get NaN.

    > /usr/local/rrdtool/bin/rrdtool last
    /home/mrtg/data/dolly.log4j.warn.rrd
    > 1188916748
    > /usr/local/rrdtool/bin/rrdtool fetch
    /home/mrtg/data/dolly.log4j.warn.rrd AVERAGE   -s 1188916748 -e
    1188916748
    >                             ds0                 ds1
    >
    > 1188916860: nan nan

The databases are created by mrtg.

I´m using mrtg 2.15.2 and rrdtool 1.2.23

regards,

Michael
