> +Question:+
> Cygnus: Bad HTTP notification (curl/7.29.0 user agent not supported)
> +Description:+
> I installed cygnus version 0.8.2 on Fiware instance basing on the image CentOS-7-x64 using:
> sudo yum install cygnus
> I configured my agent as the following:
> cygnusagent.sources = http-source
> cygnusagent.sinks = mongo-sink 
> 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 = /usr/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 = kura_
> # 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
> I tried to test it locally using the following curl command:
