Hi again,
As I said with the stratos load balancer I was getting the error that the member doesn’t exist under the cluster id with a value the cluster id of the load balancer!!!! And not maybe the cluster instance id of the application. :/ Now, with the nginx extension I start 2 different applications with nginx cartridge in both of them. When eventually everything has started the two nginx instances have information for both applications!!!!! It is supposed to behave like that? Or only hear to the topology that the application has and the nginx is included. And not hear to other applications!!!! I’m looking forward for your answers.

Mainly there are two ways you can use a load balancer in 4.1.0: 1. Start a global load balancer instance for the entire Stratos deployment. You just need to start a load balancer instance with proper MB and CEP configurations to do this. It will start listening to the entire topology and making the configuration accordingly. 2. Add a load balancer cartridge to your application and add a dependency to the cartridge which needs load balancing capabilities.

It’s really annoying to not getting any errors for the LB and simply for a misconfiguration not working at all… IMO there is no error to report in this scenario. If the load balancer is receiving a request with an unknown host it cannot delegate the request. Please make sure you find the hostname of the cluster, add a DNS entry or host entry and make the request with that.

At Stratos 4.0.0 you used the properties in the cartridges and a load balancing vm was spawned, when a php cartridge initialized using the [1] in its definition . We said let’s go to the Stratos 4.1.0. But now I cannot use correctly the load balancer. For the “Member Started”, “Member activated” topology events I get that the member doesn’t exist! But it is there working perfectly fine by its own.

In the lb cartridge you’ve added the following: "property":[ { "name":"load.balancer", "value":"true" } ] And in the php cartridge for instance: , "loadBalancer":{ "type":"lb", "property":{ "name":"default.load.balancer", "value":"true" } } And from that site it makes sense what to use http://imesh.gunaratne.org/blog/advance-load-balancing-capabilities-in-apache-stratos-incubating-4/ But now in the Stratos 4.1.0 these configurations are gone… Something changed as I can see but I cannot get it working Regards, Thanos From: Athanasios Tsitsipas [mailto:athanasios.tsitsi...@uni-ulm.de] Sent: Tuesday, June 9, 2015 10:24 AM To: dev@stratos.apache.org <mailto:dev@stratos.apache.org> Subject: Can't access application in topology instance via LB Hi again, I managed to start a Stratos Load Balancer without errors. But when another application is in the cluster cannot be accessed through load balancer. Even if I specify the host name of the app and the IP of LB to my client hosts file nothing works. I get the following error: TID: [0] [LB] [2015-06-08 22:51:13,156] WARN {org.apache.stratos.messaging.message.processor.topology.MemberStartedMessageProcessor} - Member does not exist: [service] php [cluster] php-lb.php-test.php.domain [member] php-lb.php-test.php.domain49fe383c-500a-43ec-9556-69432665448d When I start the load balancer with puppet of course the log file is attached to the mail. Just to see if there are any erroneous behaviours. Also in the loadbalancer.conf file the # Topology service filter and # Topology cluster filter there is no information for them. Only for # Topology member filter. I have also attached the loabalancer.conf of the machine. What should I do it doesn’t work apparently :/ Best regards, Thanos -- Imesh Gunaratne Senior Technical Lead, WSO2 Committer & PMC Member, Apache Stratos
