早上好，
我有以下一组虚拟机：
天鹅座配置是：

#
# General configuration template explaining how to setup a sink of each of the available types (HDFS, CKAN, MySQL).
#=============================================
# The next tree fields set the sources, sinks and channels used by Cygnus. You could use different names than the
# ones suggested below, but in that case make sure you keep coherence in properties names along the configuration file.
# Regarding sinks, you can use multiple types at the same time; the only requirement is to provide a channel for each
# one of them (this example shows how to configure 3 sink types at the same time). Even, you can define more than one
# sink of the same type and sharing the channel in order to improve the performance (this is like having
# multi-threading).

执行以下步骤时：
我订阅传感器和数据一直想要保存：
(curl http://10.10.0.10:1026/NGSI10/subscribeContext -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
{
"entities": [
{
"type": "Sensor",
"isPattern": "false",
"id": "sensor003"
}
],
"attributes": [
"potencia_max",
"potencia_min",
"coste",
"co2"
],
"reference": "http://localhost:5050/notify",
"duration": "P1M",
"notifyConditions": [
{
"type": "ONTIMEINTERVAL",
"condValues": [
"PT5S"
]
}
]
}
EOF
然后我创建或修改这些数据：
(curl http://10.10.0.10:1026/NGSI10/updateContext -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
{

{
"type": "Sensor",
"isPattern": "false",
"id": "sensor003",
"attributes": [
{
"name":"potencia_max",
"type":"float",
"value":"1000"
},
{
"name":"potencia_min",
"type":"float",
"value":"200"
},
{
"name":"coste",
"type":"float",
"value":"0.24"
},
{
"name":"co2",
"type":"float",
"value":"12"
}
]
}
],
"updateAction": "APPEND"
}
EOF
获得了预期的结果，但是当访问VM B的数据库时，为了查看他们是否创建并保存了数据，我们发现它没有发生：
admin（空）
当地0.078GB
localhost（空）
如果我们转到VM A的数据库，我们可以看到谁创建了数据库：
admin（空）
hvds_def_serv 0.078GB
hvds_qsg 0.078GB
当地0.078GB
猎户座0.078GB
我可以说明它是如何解决的吗？
提前感谢您的帮助
