Problem with more than 3Gbps Graph

[penocchio]

Dear All,

I found problem when generate RRD Graph with traffic ~3Gbps.

Problem is when snmp counter64 more than 10E+15, Graph will blank out

EX. SNMPv2-SMI::enterprises.x.x.x.x.x.x = Counter64: 106144424591342

Then I checking log, It show as belows,

OK u:0.01 s:0.01 r:21.35
OK u:0.01 s:0.01 r:23.38
OK u:0.01 s:0.01 r:25.41
OK u:0.01 s:0.01 r:26.42
OK u:0.01 s:0.01 r:28.46
OK u:0.01 s:0.01 r:30.48
OK u:0.01 s:0.01 r:31.50
ERROR: not a simple integer: '1.549119706173E+14'
OK u:0.01 s:0.01 r:35.57
ERROR: not a simple integer: '1.1182789685187E+14'
OK u:0.01 s:0.01 r:38.62
OK u:0.01 s:0.01 r:40.65
OK u:0.01 s:0.01 r:42.67
OK u:0.01 s:0.01 r:43.69

As my understanding RRD is not support only integer number not "." or "E+14"

Can anyone help me solved this issue?

Make sure you're set the device to use snmpv2 and 64bit graph templates.

Maybe your problem is more related to rrdtool than to cacti.

Sometimes, i use this short script to see what cacti ask to rrdtool :

Code: Select all

 cat /usr/bin/rrdtool.sh
#!/bin/bash
echo `date +%Y%m%d-%H:%M:%S`" : rrdtool $@" >> /tmp/rrdtool.log
chmod 0777 /tmp/rrdtool.log
if [ "$1" = "-" -o "$2" = "-" ]
        then
                tee -a /tmp/rrdtool.log | /usr/bin/rrdtool "$@" 2>> /tmp/rrdtool.log
                echo -e "\ncode retour :$?:" >> /tmp/rrdtool.log
        else
                /usr/bin/rrdtool "$@" 2>> /tmp/rrdtool.log
                echo -e "\ncode retour :$?:" >> /tmp/rrdtool.log
        fi

th chmod line is only usefull when rrdtool graph commands are launched by a different user that the used used by the poller (for example, www-data and cacti).

Use it only for a short time, insted of /usr/bin/rrdtool in the Settings/Paths section. Maybe you can get the same information in the cacti log file, but i found this way more usefull to re-play some problems on rrd filesout of cacti.
