Hi MRTG fans, We use MRTG to monitor a variety of system performance counters including Veritas Volume Manager stats from vxstat. These are reset to 0 every night.
Previously using mrtg-2.9.25 this was working fine. Since upgrading recently to mrtg-2.13.0rc4 we have been getting massive peaks on the charts every time the counter is reset. What has changed between these two versions that makes this happen? We do NOT use rrdtool. I have seen discussions of DERIVE versus COUNTER in the rrdtool list, however they seemed to apply to rrdtool only. I have also seen mention of using 64-bit counters, however I can't see a way to turn that on for values that are not collected using SNMP. Here is a sample of the log file with such a peak: 1140100286 4614739 6217096 1140100286 1397 1658 1397 1658 1140099377 1105 1580 1105 1580 1140099300 1105 1580 1105 1580 1140099000 1105 1580 1105 1580 1140098700 1139 1577 1241 1580 1140098400 1241 1572 1241 1572 1140098100 1241 1572 1241 1572 1140097800 1246705 1263538 4614073 4675521 1140097500 4614073 4675521 4614073 4675521 1140097200 4614073 4675521 4614073 4675521 1140096900 3430080 3475828 4614073 4675521 1140096600 1115 1396 1115 1396 1140096300 1115 1396 1115 1396 1140096000 1246 1372 1628 1396 1140095700 1628 1305 1628 1305 Here are the settings in the MRTG config file for that parameter: MaxBytes[_]: 999999999999 UnScaled[_]: kMG[_]: k,M,G,T,P kilo[_]: 1024 Options[_]: growright noinfo nopercent YLegend[_]: Bytes / Sec ShortLegend[_]: B/s Legend1[_]: Total reads Legend2[_]: Total writes Legend3[_]: Peak reads Legend4[_]: Peak writes LegendI[_]: reads: LegendO[_]: writes: Colours[_]: SKYBLUE#0080FF, BLUE#000080, SKYBLUE#0080FF, BLUE#000080 Target[hostname_vxtotio_diskgroupname]: `/usr/bin/ssh hostname /usr/local/bin/mrtgagent vxtot diskgroupname ` Title[hostname_vxtotio_diskgroupname]: Total I/O on Veritas Volumes in diskgroupname PageTop[hostname_vxtotio_diskgroupname]: <H1>Total I/O on Veritas Volumes in diskgroupname</H1> Any suggestions would be greatly appreciated! -- Scott Rochford -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
