问题 We are trying to install Orion Context Broker in a CentOS-7 virtual machine as recommended in this link: https://fiware-orion.readthedocs.io/en/master/admin/install/index.html When we run the step "yum install contextBroker", an HTTPS 404 error is obtained (please, see instalation log). Apparently, the repositories are not available. We can access to the URL https://nexus.lab.fiware.org/service/rest/repository/browse/el/7/x86_64/release/ from the virtual machine (see curl output) and our

问题 I try to send a subscription to my Orion Context Broker instance. I'm sending this JSON: { "duration": "P1M", "reference": "http://130.206.127.23:1026/ngsi10/notifyContext", "notifyConditions": [ { "condValues": [ "PT10s" ], "type": "ONTIMEINTERVAL" } ], "entities": [ { "id": "1.0", "type": "Capsule", "isPattern": "false" } ], "attributes": [ "temperature" ] } And I receive the next message: <subscribeContextResponse> <subscribeError> <errorCode> <code>400</code> <reasonPhrase>Bad Request<

问题 I installed the new version of ContextBroker: curl localhost:1026/version { "orion" : { "version" : "1.2.1", "uptime" : "0 d, 0 h, 7 m, 58 s", "git_hash" : "af44fd1fbdbbfd28d79ef4f929e871e515b5452e", "compile_time" : "Thu Jun 16 15:46:51 CEST 2016", "compiled_by" : "fermin", "compiled_in" : "centollo" } } Then I installed the watchdog and verifying the file /var/log/contextBroker/monitBROKER.log , I encounter the following error: error : 'contextBroker' failed to start (exit status 1) -- /etc

问题 I have set my weather station with different sensors attached. My practice until now was to send the sensor data to a web address. But now that I have set up a CentOS 6.6 on a server with its IP address so now I want to send the sensor data directly to that machine that has orion context broker installed. So my question is, how do I configure orion context broker to accept these post requests (from the weather station sensors) that are being sent to the CentOS machine? 回答1: You shouldn't have

问题 So far I have configured ContextBroker to send data to Cygnus which in turn saves data by default names in database. But what if I want to target a specific database with a specific table? I know I have to set: dbName=<fiware-service> tableName=<fiware-servicePath>_<entityId>_<entityType> I dont know where that file is, and I know it isnt in /etc/sysconfig/contextBroker because that folder doesnt exist. EDIT1: here is my updatecontext: (curl localhost:1026/NGSI10/updateContext -s -S --header

问题 I can't connect to ContextBroker from another machine, even a machine in the same LAN. Accessing by ssh without any problem ssh geezar@192.168.1.115 and then curl localhost:1026/statistics the terminal shows the statistics, all right <orion> <xmlRequests>3</xmlRequests> <jsonRequests>1</jsonRequests> <updates>1</updates> <versionRequests>1</versionRequests> <statisticsRequests>2</statisticsRequests> <uptime_in_secs>84973</uptime_in_secs> <measuring_interval_in_secs>84973</measuring_interval

问题 Orion appears not to be able to reach Cygnus, and gives the following warning (I have hidden the IP's): WARNING@13:33:21 AlarmManager.cpp[303]: Raising alarm NotificationError Y.Y.Y.Y:5050/notify: (curl_easy_perform failed: Timeout was reached) I first created an entity, then made a subscription, and subsequently updated the entity. For information, here is the entire debug logging from startup of the contextBroker: INFO@13:31:51 contextBroker.cpp[1808]: Startup completed INFO@13:32:51

问题 I'm using Orion Context Broker but the default port is not valid in my organization (a firewall is filtering out 1026 for external connections). How can I change the Orion Context Broker default port? 回答1: You can change the Orion Context Broker service port using the -port command line option. For example, if you want to use port 9999, run contextBroker using the following: contextBroker ... -port 9999 Check the Orion Context Broker administration manual for details. 来源： https:/

问题 In this question I have a problem that the orion conditions were not satisfied but it was solved by removing the quotes on the especial value Why this orion subscription don't works as I want? The new problem is that when I process an event with cep that calculates the mFlag int attribute it send it to orion but apparently it is send with the quotes (same problem as described in the related question posted before) because the orion entity is changed but the notification is not triggered. The

问题 I am trying to use cygnus with CKAN, but no data have been persisted in CKAN when the attribute is JSON type.
