Cygnus 没有更新数据库

Question

我想订阅 Orion 向 Cygnus 发送通知。然后 cygnus 会将所有数据保存在 mysql 数据库中。我用这个脚本订阅car1的速度属性

(curl 130.206.118.44:1026/v1/subscribeContext -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Fiware-Service: vehicles' --header 'Fiware-ServicePath: /4wheels' -d @- | python -mjson.tool) <<EOF
{
    "entities": [
        {
            "type": "car",
            "isPattern": "false",
            "id": "car1"
        }
    ],
    "attributes": [
        "speed",
        "oil_level"
    ],
    "reference": "http://192.168.1.49:5050/notify",
    "duration": "P1M",
    "notifyConditions": [
        {
            "type": "ONCHANGE",
            "condValues": [
                "speed"
            ]
        }
    ],
    "throttling": "PT1S"
}
EOF

但是当我更新1号车的速度属性时，cygnus并没有更新数据库。

可用的数据库：

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
+--------------------+
3 rows in set (0.00 sec)

关于我的 cygnus 服务和我的 cygnus 配置的一些信息 (systemctl status cygnus):

cygnus.service - SYSV: cygnus
   Loaded: loaded (/etc/rc.d/init.d/cygnus)

agent_mysql.conf:

# main configuration
cygnusagent.sources = http-source
cygnusagent.sinks = mysql-sink
cygnusagent.channels = mysql-channel

# source configuration
cygnusagent.sources.http-source.channels = mysql-channel
cygnusagent.sources.http-source.type = org.apache.flume.source.http.HTTPSource
cygnusagent.sources.http-source.port = 5050
cygnusagent.sources.http-source.handler = com.telefonica.iot.cygnus.handlers.OrionRestHandler

# url target
cygnusagent.sources.http-source.handler.notification_target = /notify
cygnusagent.sources.http-source.handler.default_service = def_serv
cygnusagent.sources.http-source.handler.default_service_path = def_servpath
cygnusagent.sources.http-source.handler.events_ttl = 10
cygnusagent.sources.http-source.interceptors = ts gi
cygnusagent.sources.http-source.interceptors.ts.type = timestamp
cygnusagent.sources.http-source.interceptors.gi.type = com.telefonica.iot.cygnus.interceptors.GroupingInterceptor$Builder
cygnusagent.sources.http-source.interceptors.gi.grouping_rules_conf_file = /usr/cygnus/conf/grouping_rules.conf


#Orion MysqlSink Configuration
cygnusagent.sinks.mysql-sink.channel = mysql-channel
cygnusagent.sinks.mysql-sink.type = com.telefonica.iot.cygnus.sinks.OrionMySQLSink
cygnusagent.sinks.mysql-sink.enable_grouping = false
# mysqldb ip
cygnusagent.sinks.mysql-sink.mysql_host = 127.0.0.1
# mysqldb port
cygnusagent.sinks.mysql-sink.mysql_port = 3306
cygnusagent.sinks.mysql-sink.mysql_username = root
cygnusagent.sinks.mysql-sink.mysql_password = 12345
cygnusagent.sinks.mysql-sink.attr_persistence = column
cygnusagent.sinks.mysql-sink.table_type = table-by-destination

# configuracao do canal mysql
cygnusagent.channels.mysql-channel.type = memory
cygnusagent.channels.mysql-channel.capacity = 1000
cygnusagent.channels.mysql-channel.transactionCapacity = 100

阅读 this 问题后，我在这一行中更改了 agent_mysql.conf： cygnusagent.sinks.mysql-sink.attr_persistence = column 到 cygnusagent.sinks.mysql-sink.attr_persistence = row 并重新启动了服务。然后我更新了 orion 实体并查询了数据库，但没有任何反应。

Cygnus 日志文件：http://pastebin.com/B2FNKcVf

注意：我的JAVA_HOME设置好了。

正如您在 post 编辑的日志中看到的，Cygnus 日志文件存在问题：

java.io.FileNotFoundException: ./logs/cygnus.log (No such file or directory)

之后，Cygnus 停了下来。您必须检查有关 log4j 的配置，所有内容都在 /usr/cygnus/conf/log4j.properties（它应该存在，它是由 RPM 创建的...如果不存在 - 因为您是从源而不是 RPM 获取的，它必须从创建可用模板）。另外，可以post你的实例配置文件吗？不管怎样，你是哪个版本运行?

最近，我们发现另一个用户处理同样的错误，问题是 /usr/cygnus/conf/log4j.properties 文件的内容是：

flume.root.logger=INFO,LOGFILE
flume.log.dir=./log
flume.log.file=flume.log

而不是模板包含的内容：

flume.root.logger=INFO,LOGFILE
flume.log.dir=/var/log/cygnus/
flume.log.file=flume.log

更改后它起作用了，因为 RPM 创建 /var/log/cygnus 但不是 ./log。
