Doesn't the device produce these values as separate OIDs? It seems a bit
strange that they are only available as a string. Four separate SNMP OIDs
would be much easier to manage.

MRTG will ALWAYS takes EXACTLY TWO values. Also, both values are passed to the
postprocessing script with no additional parameters. So, you should instead
have:
Target[netappTempOne]:encTempSensorsCurrentTemp.1&
encTempSensorsCurrentTemp.1:[EMAIL PROTECTED]|netappTempone
Which will extract the string (twice) and pass it to the postprocess function
(twice). So, you need multiple postprocess functions to extract different
positions in the string.

sub getitemn($$) {
my(@l) = split " ",$_[0];
my($t) = $l[$_[1]*2];
return $1 if($t =~ /(\d+)/);
return "UNKNOWN";
}
sub netappTempone { return getitem($_[0],0); }
sub netappTemptwo { return getitem($_[0],1); }
sub netappTempthree { return getitem($_[0],2); }
sub netappTempfour { return getitem($_[0],3); }
Now, this means you can only have one of the 4 temperatures per MRTG graph, so
you use the 'noo' option and create 4 targets (one per item). If you user
Routers2, you can create a userdefined graph to put all 4 lines on one image:
Target[netappTempOne]:encTempSensorsCurrentTemp.1&
encTempSensorsCurrentTemp.1:[EMAIL PROTECTED]|netappTempone
SetEnv[netappTempOne]: MRTG_INT_DESCR="1"
MaxBytes[netappTempOne]: 100
ShortLegend[netappTempOne]: degC
LegendI[netappTempOne]: 1:
Legend1[netappTempOne]: first sensor temperature
Legend3[netappTempOne]: peak first sensor temp
Title[netappTempOne]: Temp - Netapp 1 FS01
PageTop[netappTempOne]: <h1>Temp-Netapp 1 FS01</h1>
Options[netappTempOne]: noo
routers.cgi*Options[netappTempOne]: unscaled fixunit nomax nopercent
routers.cgi*Graph[netappTempOne]: netappTemp
routers.cgi*ShortDesc[netappTempOne]: Sensor 1
routers.cgi*InMenu[netappTempOne]: no
Target[netappTempTwo]:encTempSensorsCurrentTemp.1&
encTempSensorsCurrentTemp.1:[EMAIL PROTECTED]|netappTemptwo
SetEnv[netappTempTwo]: MRTG_INT_DESCR="2"
MaxBytes[netappTempTwo]: 100
ShortLegend[netappTempTwo]: degC
LegendI[netappTempTwo]: 2:
Legend1[netappTempTwo]: second sensor temperature
Legend3[netappTempTwo]: peak second sensor temp
Title[netappTempTwo]: Temp - Netapp 1 FS01
PageTop[netappTempTwo]: <h1>Temp-Netapp 1 FS01</h1>
Options[netappTempTwo]: noo
routers.cgi*Options[netappTempTwo]: unscaled fixunit nomax nopercent
routers.cgi*Graph[netappTempTwo]: netappTemp
routers.cgi*ShortDesc[netappTempTwo]: Sensor 2
routers.cgi*InMenu[netappTempTwo]: no
then repeat for the other 2 sensors. See how the Target line specifies a
different postprocess function each time - the new function extracts a
different number from the list. The routers2 extended options define a summary
graph, and hide the individual graphs from the menu.
This explanation got a bit out of hand, I've been writing MRTG documentation
examples this week...
