Get Toner Level from printers via SNMP Batch

I was asked to write a program that asks all printers in the network about there Name, Location and CMYK Toners (How many percentages are left). So i started with the OID's and tried it for only one printer. This worked. Then i wrote a .bat file with all querys i had to do. I made an array for all 97 printers. As i would use the array in the Codeline nothing worked. In my opinion the Codeline doesn't accept the array. I googled for everything and tried everything but nothing worked so I wanted to ask you what my problem is. Also I want to write it out in an .txt file.

My Code:

@echo off

setlocal enableDelayedExpansion 

SET count=0

SET a[0]= 172.22.10.3
SET a[1]= 172.22.10.2
SET a[2]= 172.22.10.1
SET a[3]= 172.22.10.5

snmpwalk -v2c -c public %a[%count%]% 5 1.3.6.1.2.1.25.3.2.1.3.1
>>C:\Temp\Drucker.txt
//Printer Name

snmpwalk -v2c -c public %a[%count%]% 1.3.6.1.2.1.1.6 >>C:\Temp\Drucker.txt
//Printer Location

snmpwalk -v2c -c public %a[%count%]% 1.3.6.1.2.1.43.11.1.1.9.1.4
>>C:\Temp\Drucker.txt
//Black Toner   

snmpwalk -v2c -c public %a[%count%]% 1.3.6.1.2.1.43.11.1.1.9.1.1
>>C:\Temp\Drucker.txt
//Cyan Toner

snmpwalk -v2c -c public %a[%count%]% 1.3.6.1.2.1.43.11.1.1.9.1.2
>>C:\Temp\Drucker.txt
//Magenta Toner

snmpwalk -v2c -c public %a[%count%]% 1.3.6.1.2.1.43.11.1.1.9.1.3
>>C:\Temp\Drucker.txt
//Yellow Toner

endlocal

The Picture is showing the error message that comes when I start the .bat file.

Solution

  • Here is the way you should iterate over an array:

    @echo off 
setlocal enabledelayedexpansion 

set hosts[0]=172.22.10.3
set hosts[1]=172.22.10.2
set hosts[2]=172.22.10.1
set hosts[3]=172.22.10.5

for /l %%n in (0,1,3) do ( 
   echo !hosts[%%n]! 
)

    The output looks like:

    172.22.10.3
172.22.10.2
172.22.10.1
172.22.10.5

    UPDATE: So you just put your snmpwalk calls into the loop like this:

    for /l %%n in (0,1,3) do ( 
    echo Getting data from host: !hosts[%%n]! 

    echo Printer Name
    snmpwalk -v2c -c public !hosts[%%n]! 1.3.6.1.2.1.1.5
    echo Printer Location
    snmpwalk -v2c -c public !hosts[%%n]! 1.3.6.1.2.1.1.6 
    echo Black Toner   
    snmpwalk -v2c -c public !hosts[%%n]! 1.3.6.1.2.1.43.11.1.1.9.1.4 
    echo Cyan Toner      
    snmpwalk -v2c -c public !hosts[%%n]! 1.3.6.1.2.1.43.11.1.1.9.1.1
    echo Magenta Toner
    snmpwalk -v2c -c public !hosts[%%n]! 1.3.6.1.2.1.43.11.1.1.9.1.2
    echo Yellow Toner
    snmpwalk -v2c -c public !hosts[%%n]! 1.3.6.1.2.1.43.11.1.1.9.1.3
)

    IMPORTANT: Consider using -Oqv option of snmpwalk to print values only.
