Hi Gayan,
Excuse me for the massive mails. I fixed the problem with the unknown 7811 port. In thrift-client-config.xml of lb module it was defind as port the 7711 and maybe the https somehow it is configured at the next port 7811. If I define as port the 7611 and secure port 7711, everything works! I don’t get any error. Still, the -Dthrift.client.config.file.path="$CARBON_HOME/repository/conf/thrift-client-config.xml" \ Is not filled in the stratos.sh. Even if you changed it in the template. It seems that it uses the arguments from the stratos.bat or something else??? Also, in the init.pp the push templates doesn’t push the stratos.sh.erb :/ Thank you for your time.

Which ip and port should I include. By default in the zip file it has: <!-- Apache thrift client configuration for publishing statistics to WSO2 CEP --> <thriftClientConfiguration> <username>admin</username> <password>admin</password> <ip>localhost</ip> <port>7711</port> </thriftClientConfiguration> At the nginx extention parameters it has also these arguments in the nginx-extension.sh -Dthrift.receiver.ip= <> -Dthrift.receiver.port=7711 What should I do? And where I can specify these ports for thrift. Also the template stratos.sh.erb is not used it seems that it takes the parameters from the stratos.bat. Can you check the file at the end, there are some syntax errors probably.

Glad to hear that you have success with the nginx. But now with the puppet module of stratos load balancer. I think there is a problem: In the stratos.sh on the spawned vm of load balancer under the folder /mnt/ …. , where the zip file of lb is unzip it misses the -Dthrift.client.config.file.path="$CARBON_HOME/repository/conf/thrift-client-config.xml" \ A line that I get an error for!

Stratos Load Balancer 2. Nginx (via extension) 3. HAproxy (via extension) First you could try to run either of these against your Stratos deployment and see whether they are working as expected (before trying the puppet module). Load balancer only requires ActiveMQ and CEP information (IP, port) to run. Do a complete build and find 1 in the following folder: https://github.com/apache/stratos/tree/master/products/load-balancer/modules/distribution Update loadbalancer.conf and thrift-client-config.xml with the above values and start the product.
