I'm trying to use WSO2SP-4.3.0 as analytics for both WSO2AM-2.6.0 and WSO2EI-6.4.0 (integrator). The only reference I found for this options is mentioned here https://docs.wso2.com/display/SP430/Analytics+Solutions
Setting up ports and solutions map:
analytics.solutions:
APIM-analytics.enabled: true
EI-analytics.enabled: true
running a worker and dashboard of the SP
Seems the stream definitions for loganalyzer is not loaded, worker throws following exceptions:
ERROR {org.wso2.carbon.databridge.core.internal.queue.QueueWorker} - Dropping wrongly formatted event sent
org.wso2.carbon.databridge.core.exception.EventConversionException: Error when converting loganalyzer:1.0.0 of event bundle with events 1
...
Caused by: org.wso2.carbon.databridge.core.exception.EventConversionException:
No StreamDefinition for streamId loganalyzer:1.0.0 present in cache
...
...
I haven't find source of the loganalyzer stream definition (even in the original ws2am-analytics-2.6.0 package).
Any help is appreciated (or shall I just disable the DAS_AGENT from APIM)?
This seems like a configuration issue. It might be easier to try one at a time to narrow down the problem. I suggest you follow [EI-Analytics] Configure WSO2 SP for WSO2 EI to configure EI analytics with SP with enabling EI analytics first.

I've just successfully implemented a JMS-message-processor in my WSO2-process. However, when logged in as an admin on the ActiveMQ console, I can view the stats of the queue but I cannot access the contents of the pending message. Instead, I see this error:
Cannot display ObjectMessage body. Reason: Failed to build body from content. Serializable class not available to broker. Reason: java.lang.ClassNotFoundException: org.apache.synapse.message.store.impl.commons.StorableMessage
Accessing the contents of a pending message is possible when using the RabbitMQ, so I figured it should also be possible with this message broker.
I've found solutions online, but they don't seem to be working, or perhaps they're out of date. Can somebody point me to the correct answer to solve this? I'm on WSO2 Integration Studio 8.1.0 and am using ActiveMQ 5.17.1.
It appears that WSO2 is using javax.jms.ObjectMessage despite the fact that there's a long list of reasons why doing so is a bad idea, including the issue you're currently facing, but I digress.
The problem here is that the implementation of the javax.jms.ObjectMessage (i.e. org.apache.synapse.message.store.impl.commons.StorableMessage in this case) must be on the classpath of any application which wants to deserialize that message. This class is not, in fact, on the classpath of ActiveMQ therefore the ActiveMQ web console cannot deserialize the message and display its contents (assuming those contents are human-readable in the first place). That's why a ClassNotFoundException is thrown.
You may be able to resolve the issue by putting org.apache.synapse.message.store.impl.commons.StorableMessage on ActiveMQ's classpath. Aside from that there's really nothing to be done.
I assume this is different for RabbitMQ because in that case WSO2 doesn't use the JMS API and uses the AMQP protocol which is not Java-centric like JMS.
Justin has explained the cause of the issue and as suggested you can try adding the class to ActiveMQ runtime and see whether it resolves the issue. This class is located in the Synapse-Core(synapse-core_2.x.x.wso2vXXX.jar). But remember although this may resolve the ActiveMQ UI issue, this message is not consumable by other systems unless they know how to deserialize it.
Let me add more details on why the message is serialized. Message serialization happens when you use the Store mediator, and when you store a message with Store Mediator it is intended to be only read by a Message Processor. Simply the serialized message can only be consumed by WSO2 Message Processors. In other words, Store Mediator and the Message processors are tightly coupled.
If message serialization is an issue for you. For example, if other systems are consuming the messages that WSO2 publishes you can try using the JMS transport to produce and to consume messages from ActiveMQ. Other than that you can also consider using JMS Inbound Endpoint to consume messages, which all use standard media types when storing the message.
I configured an ESB cluster following this documentation
https://docs.wso2.com/display/ESB500/Clustered+Deployment but I still got a problem.
In each ESB nodes I got this log
WARN - CarbonEventManagementService CEP started with clustering enabled, but SingleNode configuration given.
instead of this one
INFO - RpcMembershipRequestHandler Received JOIN message from
Is there a way to have more details on the log to get what is wrong ?
I can post configuration files if someone can help ^^
Thanks !
If you are using hostnames for localMemberHost and <member> section in axis2.xml, change them to use IPs instead.
Test cluster of two brokers, WKA membership scheme, PostgreSQL message store, working fine for a couple of days, then throwing following errors:

Startup of Message Broker looks fine, no errors, JDBC connection to PostgreSQL DB is ok, Registry mount looks ok. Then after that error appears in wso2carbon.log several times/minute.
Anyone any ideas? As far as I know nothing's changed and I don't know what it's trying to connect to.
This usually happens when client's whom connected to MB tries to create connections per message. jms is heavy connection and not recommended to create connections per each message. Therefore, please go through client implementation and verify connections are not created per message.
If by any chance you are using wso2 esb to publish/subscribe queues/topics to mb there is a property "transport.jms.CacheLevel" connection caching in esb axis2.xml.Read the documentation and use appropriate caching level for your usecase.
There was bug in connection caching property to be ignored in esb 4.8.1 which is currently fixed in 4.9.0 as well.
These are the possible cases I can think of with the given information. If you need more info please provide a detailed usecase.
While trying to follow the instructions from the wso2am (1.10.0) manual, regarding working with statistics with the wso2das (3.0.1) server i have encountered a problem.
If i choose to let the wso2am server define the stream while making the first call of the api, the wso2das server refuses to post statistics to the WSO2_STATS_DB.
If on the other hand i choose to import the analytics.car file in wso2das (as stated here ) i get an exception (AsyncDataPublisher Stream definition already exist) because the org.wso2.apimgt.statistics.request defined in the latest Analytics.car is different to the one being send from wso2am.
I pinpointed the problem in the definition of the Eventstream_request_1.0 in files
org.wso2.apimgt.statistics.request_1.0.0.json ,
throttledOutORG_WSO2_APIMGT_STATISTICS_REQUEST.xml
where the definition of the throttledOut option is missing
Is there a way to solve this issue?
Thank you.
I think your DAS is in some kind of a corrupted state. Can you first delete the car application (/repository/deployment/server/carbonapps) and then log in to DAS and go to Manage > Event > Streams and delete any existing streams. Then try again to deploy the car app in the /repository/deployment/server/carbonapps location.
If everything goes well you would see two scripts in Manage > Batch Analytics > Scripts section. Try to execute each script and see if there is any error. If not then you can point the API manager to DAS
I've been attempting to monitor the WSO2 MB 2.1.1 via JMX which appears to be a valid option for other WSO2 tools such as the ESB however the MB does not appear to be updating any of the MBeans for the Queue attributes.
Ex:
org.wso2.andes:type=VirtualHost.Queue,VirtualHost="carbon",name="testQueue"
This has a number of potentially useful attributes like the following:
ConsumerCount
ActiveConsumerCount
ReceivedMessageCount
MessageCount
However the counters always read "0" even when there are messages in the queue dropped in via the sample sender or manually.
Creating a new queue will create the following, but the issue is seen on the new queue as well.
org.wso2.andes:type=VirtualHost.Queue,VirtualHost="carbon",name="testQueue2"
Am I simply looking in the incorrect location or any other variety of user error?
Is this the intentional behavior of the application?
Do you have any suggestions which may assist in getting this data reported via JMX?
Any help would be appreciated.
Thanks
This does not appear to be functional in MB 2.1.1, it looks as if they may be moving to using the CEP or the BAM to provide metrics on some products.
