[rrd-users] 0 values in rra

[Vlad Dimitriu]

I create a database :

	/usr/local/bin/rrdtool \\
        create \\
        --start N --step 300 \\
        /somepath/db/mdm??.rrd \\
        DS:lrx:ABSOLUTE:600:-100:200 \\
        DS:ltx:ABSOLUTE:600:-100:200 \\
        RRA:AVERAGE:0.5:1:105120

at some moment, A crontab script colects the data with snmp and updates
the database :

/usr/local/bin/rrdtool 
update 
/somepath/db/mdm??.rrd 
-t lrx:ltx 
N:$FRX1[1]:$FTX1[1]

the values are corectly provided but :

rrdtool fetch /somepath/db/mdm??.rrd AVERAGE -s -1200 -e +1200

shows:


1020202800: NaN NaN
1020203100: NaN NaN
1020203400: NaN NaN
1020203700: 0.0000000000e+00 0.0000000000e+00
1020204000: 0.0000000000e+00 0.0000000000e+00
1020204300: NaN NaN
1020204600: NaN NaN
1020204900: NaN NaN
1020205200: NaN NaN
1020205500: NaN NaN



	Where am I wrong? The two data sets are not counters, just some 
parameters like the temperature. I could run the update scripts from 
crontab for days and I get only zero's in mdm??.rrd. Maybe the date of 
rra creation and the data of the first update may be wrong ?
	Any ideeas ?



Thanx !
