我正在尝试在Mongo DB中使用cygnus，但是数据库中没有数据。 这里是通知在天鹅座有：Fiware cygnus：mongo数据库中没有数据持续存在
15/07/21 14:48:01 INFO handlers.OrionRestHandler: Starting transaction (1437482681-118-0000000000)
15/07/21 14:48:01 INFO handlers.OrionRestHandler: Received data ({ "subscriptionId" : "55a73819d0c457bb20b1d467", "originator" : "localhost", "contextResponses" : [ { "contextElement" : { "type" : "enocean", "isPattern" : "false", "id" : "enocean:myButtonA", "attributes" : [ { "name" : "ButtonValue", "type" : "", "value" : "ON", "metadatas" : [ { "name" : "TimeInstant", "type" : "ISO8601", "value" : "2015-07-20T21:29:56.509293Z" } ] } ] }, "statusCode" : { "code" : "200", "reasonPhrase" : "OK" } } ]})
15/07/21 14:48:01 INFO handlers.OrionRestHandler: Event put in the channel (id=1454120446, ttl=10)
这里是我的代理配置：
cygnusagent.sources = http-source
cygnusagent.sinks = OrionMongoSink
cygnusagent.channels = mongo-channel
#=============================================
# source configuration
# channel name where to write the notification events
cygnusagent.sources.http-source.channels = mongo-channel
# source class, must not be changed
cygnusagent.sources.http-source.type = org.apache.flume.source.http.HTTPSource
# listening port the Flume source will use for receiving incoming notifications
cygnusagent.sources.http-source.port = 5050
# Flume handler that will parse the notifications, must not be changed
cygnusagent.sources.http-source.handler = com.telefonica.iot.cygnus.handlers.OrionRestHandler
# URL target
cygnusagent.sources.http-source.handler.notification_target = /notify
# Default service (service semantic depends on the persistence sink)
cygnusagent.sources.http-source.handler.default_service = def_serv
# Default service path (service path semantic depends on the persistence sink)
cygnusagent.sources.http-source.handler.default_service_path = def_servpath
# Number of channel re-injection retries before a Flume event is definitely discarded (-1 means infinite retries)
cygnusagent.sources.http-source.handler.events_ttl = 10
# Source interceptors, do not change
cygnusagent.sources.http-source.interceptors = ts gi
# TimestampInterceptor, do not change
cygnusagent.sources.http-source.interceptors.ts.type = timestamp
# GroupinInterceptor, do not change
cygnusagent.sources.http-source.interceptors.gi.type = com.telefonica.iot.cygnus.interceptors.GroupingInterceptor$Builder
# Grouping rules for the GroupingInterceptor, put the right absolute path to the file if necessary
# See the doc/design/interceptors document for more details
cygnusagent.sources.http-source.interceptors.gi.grouping_rules_conf_file = /home/egm_demo/usr/fiware-cygnus/conf/grouping_rules.conf
# ============================================
# OrionMongoSink configuration
# sink class, must not be changed
cygnusagent.sinks.mongo-sink.type = com.telefonica.iot.cygnus.sinks.OrionMongoSink
# channel name from where to read notification events
cygnusagent.sinks.mongo-sink.channel = mongo-channel
# FQDN/IP:port where the MongoDB server runs (standalone case) or comma-separated list of FQDN/IP:port pairs where the MongoDB replica set members run
cygnusagent.sinks.mongo-sink.mongo_hosts = 127.0.0.1:27017
# a valid user in the MongoDB server (or empty if authentication is not enabled in MongoDB)
cygnusagent.sinks.mongo-sink.mongo_username =
# password for the user above (or empty if authentication is not enabled in MongoDB)
cygnusagent.sinks.mongo-sink.mongo_password =
# prefix for the MongoDB databases
#cygnusagent.sinks.mongo-sink.db_prefix = kura
# prefix pro the MongoDB collections
#cygnusagent.sinks.mongo-sink.collection_prefix = button
# true is collection names are based on a hash, false for human redable collections
cygnusagent.sinks.mongo-sink.should_hash = false
# ============================================
# mongo-channel configuration
# channel type (must not be changed)
cygnusagent.channels.mongo-channel.type = memory
# capacity of the channel
cygnusagent.channels.mongo-channel.capacity = 1000
# amount of bytes that can be sent per transaction
cygnusagent.channels.mongo-channel.transactionCapacity = 100
这里是我的规则：
{
"grouping_rules": [
{
"id": 1,
"fields": [
"button"
],
"regex": ".*",
"destination": "kura",
"fiware_service_path": "/kuraspath"
}
]
}
什么，我已经错过了任何想法？在此先感谢您的帮助！
