SNMP::get — Fetch an SNMP object
Fetch an SNMP object specified in
objectId
using GET query.
If objectId
is a string, then SNMP::get()
will return SNMP object as string. If
objectId
is a array, all requested SNMP
objects will be returned as associative array of the SNMP object ids and their
values.
objectId
The SNMP object (OID) or objects
preserveKeys
When objectId
is a array and
preserveKeys
set to true
keys in results
will be taken exactly as in objectId
,
otherwise SNMP::oid_output_format property is used to determinate
the form of keys.
Returns SNMP objects requested as string or array
depending on objectId
type or false
on error.
This method does not throw any exceptions by default.
To enable throwing an SNMPException exception when some of library errors occur
the SNMP class parameter exceptions_enabled
should be set to a corresponding value. See
SNMP::$exceptions_enabled
explanation for more details.
Example #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);
?>
The above example will output something similar to:
STRING: Test server Array ( [SNMPv2-MIB::sysDescr.0] => STRING: Test server )
Example #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();
The above example will output something similar to:
Array ( [SNMPv2-MIB::sysDescr.0] => STRING: Test server [SNMPv2-MIB::sysName.0] => STRING: myhost.nodomain )
