I have a problem whit mrtg to get information from netapp 2020
what I want to monitoring is the temperature in the system.
if I run the command snmpget from linux ( ubuntu ) console I get
root at mrtg:~# snmpget -v1 -c public
SNMPv2-SMI::enterprises.789. = STRING: "33C (91F), 31C (87F), 30C (86F), 34C (93F)"
The result is: STRING: "33C (91F), 31C (87F), 30C (86F), 34C (93F)"
And the value I want mrtg to monitoring is 33, 31, 30, 34
In the mrtg.cfg file I have this information.

LoadMIBS: /etc/mrtg/temp/netapp.mib
ConversionCode: /etc/mrtg/temp/MyConversions.pl
Target[netappTemp]:encTempSensorsCurrentTemp.1:public at|netappTemp
SetEnv[netappTemp]: MRTG_INT_IP="" MRTG_INT_DESCR="1"
MaxBytes[netappTemp]: 60
Title[netappTemp]: Temp – Netapp 1 FS01
PageTop[netappTemp]: <h1>Temp—Netapp 1 FS01</h1>

And MyConversion.pl looks like this
Sub netappTemp{
The Problem is the MyConversion.pl file. I don’t know what I write inside it.
I have trid to find information on the internet on how the perl langugare works and how to get it working whit mrtg to get the temperatures monitored
Help me.

Kind Regards
