Scott,

I don't know exactly what changed between these two versions. As work around 
you can lower the MaxBytes value for this specific counter.
If the part of the logfile is representive for the normal traffic flow you can 
set the Maxbytes to something like 3000 to avoid peaks higher than this value 
and still have all the normal traffic graphed.

HTH,

Jan.

Subject: [mrtg] Massive peaks on counter resets


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

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!
