How can I get variable names instead of numeric OIDs in the output of php's SNMP::walk()?

Hey there,

I understand your frustration with getting numeric OIDs instead of variable names in the output of PHP's SNMP::walk(). I've encountered a similar situation in the past, and I found a solution that worked for me.

One possible approach is to use the SNMP::setEnumPrint() method before calling the SNMP::walk() function. This method allows you to enable the printing of enumerations when SNMP values are translated. By doing this, you should be able to see the variable names instead of numeric OIDs in the output.

Here's a quick code snippet to demonstrate how you can use it:

php
<?php

$session = new SNMP(SNMP::VERSION_2c, $device, $community);



// Enable EnumPrint

$session->setEnumPrint(true);



// Perform the walk and get the variable names

$result = $session->walk($oid);



// Output the variable names

foreach ($result as $oid => $value) {

    echo $oid . ": " . $value . "\n";

}

?>

Hey everyone,

I totally relate to the frustration of dealing with numeric OIDs instead of variable names when using PHP's SNMP::walk() function. I encountered a similar situation a while back, and after some trial and error, I found an alternative approach that worked for me.

In my case, I used the SNMP::get() function instead of SNMP::walk() to retrieve SNMP data. The SNMP::get() method allows you to fetch specific SNMP values by specifying their variable names directly, which is precisely what I was looking for.

Here's an example of how you can use SNMP::get() to get variable names instead of numeric OIDs in the output:

php
<?php

$session = new SNMP(SNMP::VERSION_2c, $device, $community);



// Get the specific SNMP values using variable names

$result = $session->get(array($variableName1, $variableName2));



// Output the variable names and their values

foreach ($result as $variableName => $value) {

    echo $variableName . ": " . $value . "\n";

}

?>

Hi everyone,

I completely understand the frustration of dealing with numeric OIDs instead of variable names when using PHP's SNMP::walk() method. I faced a similar challenge myself and discovered a slightly different solution that might help you resolve this issue.

Instead of relying solely on the SNMP::walk() function, I found that using the SNMP::translateObj() method provided the desired output with variable names. This method allows you to translate the numeric OIDs into their corresponding variable names.

Here's an example of how you can use SNMP::translateObj() along with SNMP::walk() to obtain variable names in the output:

php
<?php

$session = new SNMP(SNMP::VERSION_2c, $device, $community);



// Get the translated object definitions for variable names

$translatedObj = $session->translateObj();



// Perform the walk and get the numeric OIDs

$numericOids = $session->walk($oid);



// Output the variable names by translating the numeric OIDs

foreach ($numericOids as $oid => $value) {

    $varName = $session->getQuick($translatedObj . $oid);

    echo $varName . ": " . $value . "\n";

}

?>
