SNMP::get — Fetch an SNMP object
Fetch an SNMP object specified in
object_id
using GET query.
If object_id
is a string, then SNMP::get()
will return SNMP object as string. If
object_id
is a array, all requested SNMP
objects will be returned as associative array of the SNMP object ids and their
values.
object_id
The SNMP object (OID) or objects
preserve_keys
When object_id
is a array and
preserve_keys
set to TRUE
keys in results
will be taken exactly as in object_id
,
otherwise SNMP::oid_output_format property is used to determinate
the form of keys.
Returns SNMP objects requested as string or array
depending on object_id
type or FALSE
on error.
Esse método não lança nenhuma exceção por padrão.
Para ativar o lançamento de exceções SNMPException quando algum erro ocorrer,
o parâmetro exceptions_enabled
deve ser configurado. Veja
SNMP::$exceptions_enabled
essa explicação para mais detalhes.
Exemplo #1 Single SNMP object
Single SNMP object may be requested in two ways: as string resulting string return value or as single-element array with associative array as output.
<?php
$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
$sysdescr = $session->get("sysDescr.0");
echo "$sysdescr\n";
$sysdescr = $session->get(array("sysDescr.0"));
print_r($sysdescr);
?>
O exemplo acima irá imprimir algo similar à:
STRING: Test server Array ( [SNMPv2-MIB::sysDescr.0] => STRING: Test server )
Exemplo #2 Multiple SNMP objects
$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
$results = $session->get(array("sysDescr.0", "sysName.0"));
print_r($results);
$session->close();
O exemplo acima irá imprimir algo similar à:
Array ( [SNMPv2-MIB::sysDescr.0] => STRING: Test server [SNMPv2-MIB::sysName.0] => STRING: myhost.nodomain )
