snmpwalk -- Fetch all the SNMP objects from an agent

Description

array snmpwalk (string hostname, string community, string object_id [, int timeout [, int retries]])

Returns an array of SNMP object values starting from the object_id() as root and false on error.

snmpwalk() function is used to read all the values from an SNMP agent specified by the hostname. Community specifies the read community for that agent. A 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.

 
$a = snmpwalk("127.0.0.1", "public", ""); 
      

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


for ($i=0; $i<count($a); $i++) {
    echo $a[$i];
}
