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_rsnmprealwalk('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.
