[rrd-users] Re: Problems with RRD and graphing BIND...........

[Serge Maandag]

I don't see what's wrong at first glance, are you sure your script is
outputting valid data?
Not something like: N:12:13::20:5: ?

What I do see though:

"RRA:AVERAGE:0.5:6:17520",
"RRA:AVERAGE:0.5:24:4380",

6 * 17520  is the same timespan as 24 * 4380, so the second one
effectively does nothing and will not be used.

Serge.

Hi,
 
i know what i am going to ask might be something i should be able to
find somewhere in the docs but for some reason i am not.
I have a script which uses the named.stats file to extract the nbr of
queries and some other stuff of my dns server. So far so good
but when i try to enter all this in rrd i am not getting anything back.
 
First off i created my rrd file like this..
 
RRDs::create ($rrd, "--start",$start-1, "--step",300,
              "DS:ok:GAUGE:600:U:U",
              "DS:fail:GAUGE:600:U:U",
              "DS:referal:GAUGE:600:U:U",
              "DS:nxrrset:GAUGE:600:U:U",
              "DS:nxdomain:GAUGE:600:U:U",
              "DS:recursion:GAUGE:600:U:U",
              "RRA:AVERAGE:0.5:1:7000",
              "RRA:AVERAGE:0.5:6:17520",
              "RRA:AVERAGE:0.5:24:4380",
              "RRA:AVERAGE:0.5:288:1825",
              "RRA:MAX:0.5:1:7000",
              "RRA:MAX:0.5:6:17520",
              "RRA:MAX:0.5:24:4380",
              "RRA:MAX:0.5:288:1825",
              "RRA:MIN:0.5:1:7000",
              "RRA:MIN:0.5:6:17520",
              "RRA:MIN:0.5:24:4380",
              "RRA:MIN:0.5:288:1825");
 
i want to store the data for quite some time, thats why i have these
large values........ and i chose gauge since i will pass a nbr for each
DS
which reflect nbrs of querys for the 5 Min interval. Also i want to keep
track of the max values an Min Values. I hope this is ok so far. 
Now i run a script every 5 minutes which feeds the data into the rrd
db.....
 
RRDs::update
("bindns2laxus.rrd","N:$ok:$fail:$referal:$nxrrset:$nxdomain:$recursion"
);
 
which seems to run fine because i dont get any errors.....
 
then when i try to graph this i get nothing but a blank graph...
 
/usr/local/rrdtool-1.0.41/bin/rrdtool graph -w 650 -h 200
myrouter-dns.png --start -3600 \
DEF:dnsok=bindns2laxus.rrd:ok:AVERAGE  \
DEF:dnsfail=bindns2laxus.rrd:fail:AVERAGE \
DEF:dnsreferal=bindns2laxus.rrd:referal:AVERAGE \
DEF:dnsnxrrset=bindns2laxus.rrd:nxrrset:AVERAGE \
DEF:dnsnxdomain=bindns2laxus.rrd:nxdomain:AVERAGE \
DEF:dnsrecursion=bindns2laxus.rrd:recursion:AVERAGE \ 
AREA:dnsok#00FF00:"Ok" \
LINE1:dnsfail#0000FF:"Fail" \ 
LINE2:dnsreferal#FF00FF:"Referal" \ 
LINE3:dnsnxrrset#FF0000:"Nxrrset" \
LINE4:dnsnxdomain#555555:"Nxdomain" \ 
LINE5:dnsrecursion#FFFFFF:"Recursion"
 
 
I hope someone can point me here in the right direction...
Thanks
 
Alex
