Hi experts!
I know of a lot of post talk about NAN, but I can't resolve it.
I try this:
rrdtool create temperature.rrd --step 300 \
DS:temp:GAUGE:600:-273:5000 \
RRA:AVERAGE:0.5:1:1200 \
RRA:MIN:0.5:12:2400 \
RRA:MAX:0.5:12:2400 \
RRA:AVERAGE:0.5:12:2400
and this (with different value)
rrdtool update temperature.rrd N:25
And I obtain this:
nsp-nms:/usr/local/cacti/rra# rrdtool fetch temperature.rrd MAX
timestamp temp
1211392800: nan

So this is bad, but not so bad because in rrdtool info I found:
rra[3].cdp_prep[0].value = 2.4792592593e+01

My realy problem is:
I make this script for cacti:

The main probleme is this:
.cdp_prep[0].value = NaN
I hope of I'm clear...
I'm newbee with rrdtool!
Just for info:
I want display in cacti the number of IP packet with a size of 32 and 64.
My script called by cacti:
#!/usr/bin/perl
if (!$ARGV[0]){
print "error: Bad argument\n";
print "usage: ./snmp_netflow.pl [IP Address]\n";
exit 1;
}
open(PROCESS, "snmpget -m all -c public -v2c $ARGV[0]
cnfPSPacketSizeDistribution.0|");
@snmpget = <PROCESS>;
close(PROCESS);
chomp(@snmpget); # enleve les '\n' a la fin des lignes
my $string = join(" ",@snmpget);
if ($string =~ m/Hex-STRING:(.*)/) {
my $hex = $1;
#print "$hex\n";
my $i = 0;
# Tant que l'on trouve deux nombres (separés par des blancs)
while ($hex =~ m/(\w{2})\s+(\w{2})/g) {
if ($i >= 1024) {
$i = $i + 512;
}
else {
$i += 32;
if ($i == 576+32){
$i = 1024;
}
}
if ($i < 64){
print "$i:" . sprintf("%d",hex("$1$2") / 10) . " ";
}
if ($i == 64){
print "$i:" . sprintf("%d",hex("$1$2") / 10);
}
if ($i > 64){
exit 1;
}
}}
I hope of I didn't post 2 times, if I did it, I'm really sorry!
