I just finished testing the entire thing on my virtual machine environment and now I am trying to launch it on the dedicated server. And now I ran into a completely new issue. First I confirmed that I have both context Broker and centos running (on 1026 and 5050 respectively):
[root@centos conf]# netstat -ntlpd
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp 0 0 :::22 :::* LISTEN 1260/sshd
tcp 0 0 :::5050 :::* LISTEN 2481/java
[root@centos conf]# service cygnus status
Cygnus 1 status...
cygnus-flume-ng (pid 2481) is running...
Then I confirmed that I have data on contextBroker because this command gave me an appropriate response:
(curl localhost:1026/v1/queryContext -s -S --header 'Content-Type: application/json' \
--header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
{
"entities": [
{
"type": "Room",
"isPattern": "false",
"id": "Room1"
}
]
}
EOF
Following the workaround to an issue with root user and logging I fixed the log4j.properties and changed the follwing:
flume.log.dir=/var/log/cygnus
I then started cygnus and got the following log:
Starting an ordered shutdown of Cygnus

Then I tried to subscribe the previously mentioned data to cygnus:

Even after I updated the information on context Broker thinking it would trigger an event:
(curl localhost:1026/v1/updateContext -s -S --header 'Content-Type: application/json' \

]
}
],
"updateAction": "APPEND"
}
EOF
But the cygnus log remainged exactly the same and its like nothing even got through to it. Which is odd considering my agent_1.conf:

#============================================
It has 5050 and notify as the reference address. I double checked the cygnus_instance_1.conf as well and it is pointing at agent_1.conf

This is the content of my config folder in /usr/cygnus/conf:
[root@centos conf]# ls
agent_1.conf cygnus_instance_1.conf flume-env.sh grouping_rules.conf krb5.conf krb5_login.conf log4j.properties.template
agent.conf.template cygnus_instance.conf.template flume-env.sh.template grouping_rules.conf.template krb5.conf.template log4j.properties README.md
I noticed that there is an exacted mirror of this in /etc/cygnus/conf but I didn't touch anything because the installation only intructs me to use the /usr/ folder.
Here is my Mysql create statement. In this table I am expecting to receive the context broker data but I get nothing of course since the log didnt register anything.
CREATE TABLE sensor_room1_room (
sensorID INT NOT NULL AUTO_INCREMENT,
recvTime mediumtext,
fiwareservicepath text,
entityId text,
entityType text,
pressure text,
pressure_md text,
temperature text,
temperature_md text,
PRIMARY KEY (sensorID));
Edit 1:
Here is the listener
[root@centos conf]# nc -l 5050
But when I tried subscribing or updating context, nothing was received on the listener side. I am not taking into account the client side of nc: nc 127.0.0.1 5050 because it successfully sends everything i type (even gibberish).
I also tried the test: /usr/cygnus/bin/cygnus-flume-ng agent --conf /usr/cygnus/conf/ -f /usr/cygnus/conf/agent_1.conf -n cygnusagent -Dflume.root.logger=DEBUG,console. I tried both 5050 and 8081 ports to subscribe to and then update context but nothing is read on the console.
