Hello everyone, I apologize in advance for my newbieness with RRDtool, but I have wrestled with this problem for over 2 weeks and have come up with no solution. Nor have I seen anything like this mentioned in the mailing list archives. I will say that RRDtool looks quite awesome still despite my headaches though, which are probably induced by some little thing I missed in the manuals.
The Setup: I have a perl script which is executed by cron every 5 minutes. The perl script performs an snmpget on said device and collects the inOctets and outOctets and places the info into a .rrd via an rrdtool update command. ## Typical perl script used to pull data #!/usr/bin/perl $community = "xxx"; $hostname = "192.168.0.254"; $snmpget = "snmpget -Oqv -c $community $hostname"; $ifInOctets = `$snmpget 2.2.1.10.2`; $ifOutOctets = `$snmpget 2.2.1.16.2`; chomp ($ifInOctets); chomp ($ifOutOctets); $thereitgoes = `rrdtool update /home/somedir/perl/flapflap.rrd N:$ifInOctets:$ifOutOctets`; ##END PERL SCRIPT ##Typical command used to create the rrd rrdtool create somerrd.rrd DS:input:COUNTER:600:U:U DS:output:COUNTER:600:U:U RRA:AVERAGE:0.5:1:600 RRA:AVERAGE:0.5:6:700 RRA:AVERAGE:0.5:24:775 RRA:AVERAGE:0.5:288:797 RRA:MAX:0.5:1:600 RRA:MAX:0.5:6:700 RRA:MAX:0.5:24:775 RRA:MAX:0.5:288:797 ##Typical command run to graph rrdtool graph somerrd.gif --start -86400 DEF:inoctets=somerrd.rrd:input:AVERAGE DEF:outoctets=somerrd.rrd:output:AVERAGE AREA:inoctets#00FF00:"In traffic" LINE1:outoctets#0000FF:"Out traffic" The Problem: The data is totally off in the rrd. It may show anywhere from constant 50 M (million) to 1.5 G (giga) at all times (I tried using it to graph a server at one point, and a router at another time, I have gotten rrd to successfully graph two workstations though). There is no possible way that these devices could pass this much data a second.. also, I can manually pull the octets, then five minutes later pull the octets again and manually do the math and everything looks ok. When I let rrdtool do the work for me, it just shows extraordinarily huge numbers. Any idea why this is? If you need more info about my problem, I will be more than happy to provide it. Thanks in advance for any assistance.
