Hi
I have now found the problem. It is a localization problem and explains why I
did
not get it when I tried it the first time.
With LANG=sv_SE.UTF-8
I get the following with some extra debug code:
Mar 25 22:22:01 localhost ntop[29502]: RRD: rrdtool create arg: rrd_create

rrd_update(/var/lib/ntop/interfaces/eth0/throughput.rrd) error: opening

With LANG=C I get the following:
Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg: rrd_create
Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg:

Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg: 1206480658
Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg: --step
Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg: 20

Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg:
RRA:AVERAGE:0.5:1:12960
Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg:
RRA:MIN:0.5:1:72
Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg:
RRA:MAX:0.5:1:72
Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg:
RRA:AVERAGE:0.5:180:2160
Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg:
RRA:AVERAGE:0.5:4320:1080
Mar 25 22:31:00 localhost ntop[30466]: RRD: rrdtool create arg:
RRA:HWPREDICT:1440:0.1:0.0035:20
So the quick workaround is to set LANG=C.
It is quite obvious that 0.5 and 0,5 are different! :)
Obviously the problem is the use of
safe_snprintf(__FILE__, __LINE__, monthsStr, sizeof(monthsStr),
"RRA:AVERAGE:%.1f:%d:%d",
0.5, value1, dumpMonths * 30);
This converts the 0.5 to a 0,5 if LANG != C.
So I have added "export LANG=C" to the debian init script as a workaround.
Best regards,
