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.
