Mike,

I think your maxbytes may be set to low.   1024 bytes?

Subject: [mrtg] log not keeping historical data


I have MRTG running on a Windows 2003 Server using IIS 6.0 as the webserver.
I
am trying to monitor Windows 2000 Servers and have been able to successfully
monitor and graph CPU, free drive space on C, NIC utilization, and Page
Faults
Per Sec, but I am having a hell of a time with Free Memory and Commited
Memory.
Below is a portion of my cfg file.  I have multiple sections identical to
this
and they are all experiencing the same issue, the log file does not keep any
historical data.  Just the currently returned values.  If I use GetIf and
continually SNMPGET on the specific OID, .1.3.6.1.4.1.311.1.1.3.1.1.1.2.0, I
can
see the value fluctuate and when compared to the stats that are displayed on
the
Performance tab of Task Manager they seem to correspond.  So I think I can
safely assume that I am using the correct OID.  The same applies to OID
.1.3.6.1.4.1.311.1.1.3.1.1.1.3.0

### Global Config Options

Logdir: x:\inetpub\wwwroot\mrtg\logs
Htmldir: x:\inetpub\wwwroot\mrtg
Imagedir: x:\inetpub\wwwroot\mrtg\images

RunAsDaemon: Yes
Refresh: 300
Interval: 5

### Global Defaults

#  to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits

Options[_]: growright,gauge

### Available Memory vs. Commited

Target[xxx.xxx.xxx.xxx_FREE_COMMIT]:
1.3.6.1.4.1.311.1.1.3.1.1.1.2.0&1.3.6.1.4.1.311.1.1.3.1.1.1.3.0:pgpmrtg at xxx.
xxx.xxx.xxx
MaxBytes[xxx.xxx.xxx.xxx_FREE_COMMIT]: 1024
Title[xxx.xxx.xxx.xxx_FREE_COMMIT]: Available vs Committed Bytes
PageTop[xxx.xxx.xxx.xxx_FREE_COMMIT]: <H1>Available Memory</H1>
kMG[xxx.xxx.xxx.xxx_FREE_COMMIT]: M,G
Unscaled[xxx.xxx.xxx.xxx_FREE_COMMIT]: dwmy
# Supress[xxx.xxx.xxx.xxx_FREE_COMMIT]:dwmy
XSize[xxx.xxx.xxx.xxx_FREE_COMMIT]: 380
YSize[xxx.xxx.xxx.xxx_FREE_COMMIT]: 100
YLegend[xxx.xxx.xxx.xxx_FREE_COMMIT]: Bytes
ShortLegend[xxx.xxx.xxx.xxx_FREE_COMMIT]: Bytes
Legend1[xxx.xxx.xxx.xxx_FREE_COMMIT]: Available Memory (Bytes)
Legend2[xxx.xxx.xxx.xxx_FREE_COMMIT]: Committed Memory (Bytes)
# Legend3[xxx.xxx.xxx.xxx_FREE_COMMIT]:
# Legend4[xxx.xxx.xxx.xxx_FREE_COMMIT]:
LegendI[xxx.xxx.xxx.xxx_FREE_COMMIT]: Avail:&nbsp
LegendO[xxx.xxx.xxx.xxx_FREE_COMMIT]: Commit:&nbsp


### Corresponding Log

1063891156 719548416 255483904
1063891156 0 0 0 0
1063890921 0 0 0 0
1063890900 0 0 0 0
1063890600 0 0 0 0

### Notice all the columns have changed, but it still isn't keeping a
history of
the data

1063899128 664395776 280588288
1063899128 0 0 0 0
1063898700 0 0 0 0
1063898400 0 0 0 0

### I have since added Options to the target

Title[xxx.xxx.xxx.xxx_FREE_COMMIT]: Available vs Committed Bytes
Options[xxx.xxx.xxx.xxx_FREE_COMMIT]: growright,gauge
PageTop[xxx.xxx.xxx.xxx_FREE_COMMIT]: <H1>Available Memory</H1>

Any ideas would be greatly appreciated as I have worn our Google looking for
clues and/or answers.

Thanks,
Mike
