I'm turning the collective genius of the MRTG list for assistance with this problem :). I'm wanting to use net-snmp to monitor CPU usage information. I went through the tutorial at the net-snmp website and configuring MRTG as instructed did not provide expected results.
The system I'm monitoring is a dual CPU FreeBSD box (FBSD 4.8-RELEASE-p13). Doing a snmp walk on the ssCpuRawIdle, etc results in an incrementing counter. Checking the log files for the target also shows increment. However, the graph is all wrong. Below I will include the relevant config entries. mrtg.cfg LoadMIBs: /usr/local/share/snmp/mibs/UCD-SNMP-MIB.txt ... Include: /usr/local/etc/mrtg/cpu.cfg cpu.cfg WithPeak[arthur.cpusum]:n Options[arthur.cpusum]: growright,nopercent RouterUptime[arthur.cpusum]: [EMAIL PROTECTED] Target[arthur.cpusum]:ssCpuRawUser.0&ssCpuRawIdle.0:[EMAIL PROTECTED] MaxBytes[arthur.cpusum]: 100 Title[arthur.cpusum]: CPU LOAD PageTop[arthur.cpusum]: <H1>Active CPU Load %</H1> Unscaled[arthur.cpusum]: ymwd ShortLegend[arthur.cpusum]: % YLegend[arthur.cpusum]: CPU Utilization Legend1[arthur.cpusum]: Idle CPU in % Legend2[arthur.cpusum]: User CPU in % Legend3[arthur.cpusum]: Maximum CPU Active Legend4[arthur.cpusum]: Maximum CPU Idle LegendI[arthur.cpusum]: User LegendO[arthur.cpusum]: Idle arthur.cpusum.log 1066017228 7471223 25885963 1066017228 2 0 2 0 1066016928 2 0 2 0 1066016700 2 0 2 0 1066016400 5 0 7 0 1066016100 3 0 7 0 1066015800 2 0 3 0 1066015500 2 0 2 0 1066015200 2 0 2 0 1066014900 2 0 2 0 arthur.cpusum.old 1066016928 7470682 25810851 1066016928 2 0 2 0 1066016628 2 0 2 0 1066016400 5 0 7 0 1066016100 3 0 7 0 1066015800 2 0 3 0 1066015500 2 0 2 0 1066015200 2 0 2 0 1066014900 2 0 2 0 1066014600 2 0 2 0 You can see the graph in all its broken glory at http://www.silvertree.org/performance/arthur.cpusum.html CPU idle should be high 90%, not 0% This little problem is most vexing, and I thank you all for your help. -- PGP Key: http://archon.silvertree.org/pgp.txt (also on various key servers) "Compassion and retribution are two sides of the same coin.
