snmp_read_mib

(PHP 5, PHP 7, PHP 8)

snmp_read_mib — Reads and parses a MIB file into the active MIB tree

Descrizione

snmp_read_mib(string $filename): bool

This function is used to load additional, e.g. vendor specific, MIBs so that human readable OIDs like VENDOR-MIB::foo.1 instead of error prone numeric OIDs can be used.

The order in which the MIBs are loaded does matter as the underlying Net-SNMP library will print warnings if referenced objects cannot be resolved.

Elenco dei parametri

filename: The filename of the MIB.

Valori restituiti

Restituisce true in caso di successo, false in caso di fallimento.

Esempi

Example #1 Using snmp_read_mib()

<?php
 print_r( snmprealwalk('localhost', 'public', '.1.3.6.1.2.1.2.3.4.5') );
 
 snmp_read_mib('./FOO-BAR-MIB.txt');
 print_r( snmprealwalk('localhost', 'public', 'FOO-BAR-MIB::someTable') );
?>

The above example is made up but the results would look like:

     
Array
(
    [iso.3.6.1.2.1.2.3.4.5.0] => Gauge32: 6
)
Array
(
    [FOO-BAR-MIB::someTable.0] => Gauge32: 6
)

If you are trying to import mibs with dependencies on other mibs you will have to set the MIBDIRS environment variable.

Unix / Linux: export MIBDIRS=/home/<user>/MIBS:/usr/share/snmp/mibs
Window: Good luck! No really.  Try this url out.  It has everything that you need to know about setting environment vars in windows.

Importing massive Mibs located in a directory
<?php
/******************** Loading Mibs **************/
 $mib_path='YourPath';    
 if ($handle = opendir($mib_path)) 
 { echo "Directory handle: $handle <br>";
    echo "Files: <br>";
    while (false !== ($file = readdir($handle))) 
    { if($file!='.')
       { if($file!='..')
          { echo "Read : ";        
            echo "$mib_path.$file";
            if(snmp_read_mib($mib_path.'\\'.$file)) echo " Succesful <br>";
            else echo " Failed <br>";
         }
        }
    }
}
closedir($handle);
