snmpwalkoid — Query for a tree of information about a network entity
$hostname
, string $community
, string $object_id
[, int $timeout = 1000000
[, int $retries = 5
]] )
snmpwalkoid() function is used to read all object ids
and their respective values from an SNMP agent specified by
hostname.
The existence of snmpwalkoid() and snmpwalk() has historical reasons. Both functions are provided for backward compatibility. Use snmprealwalk() instead.
hostname
The SNMP agent.
community
The read community.
object_id
If NULL, object_id is taken as the root of
the SNMP objects tree and all objects under that tree are returned as
an array.
If object_id is specified, all the SNMP objects
below that object_id are returned.
timeout
The number of microseconds until the first timeout.
retries
The number of times to retry if timeouts occur.
Returns an associative array with object ids and their respective
object value starting from the object_id
as root or FALSE on error.
Przykład #1 snmpwalkoid() Example
<?php
$a = snmpwalkoid("127.0.0.1", "public", "");
for (reset($a); $i = key($a); next($a)) {
echo "$i: $a[$i]<br />\n";
}
?>
Above function call would return all the SNMP objects from the SNMP agent running on localhost. One can step through the values with a loop
