How do I create and array with two heads and LOTS of members - powershell

Question

Preface: Please tell me a better way of doing this if you know of any! Even if it changes everything.
I have a powershell script that works with Net-SNMP to store the current value of an OID, change it and then check and store the values. Right now the previous and new values are stored in their own variable. There are about 160 OIDs that I need to change on >1000 nodes in my environment.
For Example for Previous and New values:
$P_vpwrSystemTempCompensation_0 = & '.\SnmpGet.exe' -q -r:"$ip" -v:2c -c:public -o:.1.3.6.1.4.1.13858.2.2.1.0
$N_vpwrSystemTempCompensation_0 = & '.\SnmpGet.exe' -q -r:"$ip" -v:2c -c:public -o:.1.3.6.1.4.1.13858.2.2.1.0
I'm try to figure the best way to store these and output into an CSV. I would like it to be formatted liked this:
Each CSV will be saved with the name and IP of the node I'm hitting.

Answer 1

You can make an object like this in a loop, and that could be exported to csv:
$oid = 'vpwrSystemTempCompensation.0'
$prev = 2
$new = 4647
[pscustomobject]#{OID=$oid; Previous=$prev; New=$new}
OID Previous New
--- -------- ---
vpwrSystemTempCompensation.0 2 5647
By the way, you don't need the call operator to run smnpget, if you don't put it in quotes:
.\SnmpGet.exe -q -r:$ip -v:2c -c:public -o:.1.3.6.1.4.1.13858.2.2.1.0
