When iterator gets advanced by :py:mod:`asyncio` main loop, SNMP TRAP or INFORM notification is send (:RFC:`1905#section-4.2.6`). The iterator yields :py:class:`asyncio.Future` which gets done whenever response arrives or error occurs. Parameters ---------- snmpEngine : :py:class:`~pysnmp.hlapi.SnmpEngine` Class instance representing SNMP engine. authData : :py:class:`~pysnmp.hlapi.CommunityData` or :py:class:`~pysnmp.hlapi.UsmUserData` Class instance representing SNMP credentials. transportTarget : :py:class:`~pysnmp.hlapi.asyncio.UdpTransportTarget` or :py:class:`~pysnmp.hlapi.asyncio.Udp6TransportTarget` Class instance representing transport type along with SNMP peer address. contextData : :py:class:`~pysnmp.hlapi.ContextData` Class instance representing SNMP ContextEngineId and ContextName values. notifyType : str Indicates type of notification to be sent. Recognized literal values are *trap* or *inform*. varBinds: tuple Single :py:class:`~pysnmp.smi.rfc1902.NotificationType` class instance representing a minimum sequence of MIB variables required for particular notification type. Alternatively, a sequence of :py:class:`~pysnmp.smi.rfc1902.ObjectType` objects could be passed instead. In the latter case it is up to the user to ensure proper Notification PDU contents. Other Parameters ---------------- \*\*options : Request options: * `lookupMib` - load MIB and resolve response MIB variables at the cost of slightly reduced performance. Default is `True`. Yields ------ errorIndication : str True value indicates SNMP engine error. errorStatus : str True value indicates SNMP PDU error. errorIndex : int Non-zero value refers to `varBinds[errorIndex-1]` varBinds : tuple A sequence of :py:class:`~pysnmp.smi.rfc1902.ObjectType` class instances representing MIB variables returned in SNMP response. Raises ------ PySnmpError Or its derivative indicating that an error occurred while performing SNMP operation. Notes ----- The `sendNotification` generator will be exhausted immidiately unless an instance of :py:class:`~pysnmp.smi.rfc1902.NotificationType` class or a sequence of :py:class:`~pysnmp.smi.rfc1902.ObjectType` `varBinds` are send back into running generator (supported since Python 2.6). Examples -------- >>> import asyncio >>> from pysnmp.hlapi.asyncio import * >>> >>> @asyncio.coroutine ... def run(): ... errorIndication, errorStatus, errorIndex, varBinds = yield from sendNotification( ... SnmpEngine(), ... CommunityData('public'), ... UdpTransportTarget(('demo.snmplabs.com', 162)), ... ContextData(), ... 'trap', ...
