I was working with siddhi Complex Event Processor by running worker.sh and encountered that maximum number of rules that can be created in siddhi is 675. beyond which Post to /siddhi-apps is failing for creation of new rule. can you please let me how can this be enhanced to more than 1000.

I am using config update and cloud functions for communication between mobile application and esp32 device by following the example here, but when I am sending config update messages frequently some of them are not sending; say out of 5 only 3 config update messages are going, I have two questions:
1) How frequently we can send config update to avoid some missing updates.
2) Is there any alternative way to communicate between cloud functions and IoT device.
According to the docs: [IoT docs]
Configuration updates are limited to 1 update per second, per device.
However, for best results, device configuration should be updated much
less often — at most, once every 10 seconds.
The update rate is calculated as the time between the most recent
server acknowledgment and the next update request.
If your operations are mostly configuration updates I cannot think another alternative that could perform better.
We are doing evaluation for metering purpose using WSO2 API Manager and DAS. (Latest versions)
Environment:
WSO2 API Manager runs as 2 node active-active deployment model using Hazlecast. (4 Core 8GB Ram) &
DAS runs as single node.
Both are connecting to backend RDBMS as mysql.
DAS and MYSQL shares the same server of 12 Core 24GB RAM. We dedicatedly allocated 12GB to MYSQL.
We started the test at the rate of 750reads/sec and everything went well for 27hrs until the metering reaches 72 Million and after which we have got the below error.
At API Manager: [PassThroughMessageProcessor-130] WARN DataPublisher Event queue is full, unable to process the event for endpoint Group.
At Das: (After 10 mins), we have got INFO {com.leansoft.bigqueue.page.MappedPageFactoryImpl} - Page file /$DAS_HOME/repository/data/index_staging_queues/4P/index/page-12.dat was just deleted. {com.leansoft.bigqueue.page.MappedPageFactoryImpl}.
Is this something that we have reached the limit w.r.t the infra setup or some performance issues w.r.t DAS. Can you please help us?
You need to tune the server performance of DAS and APIM
We have deployed API-M 2.1 in a distributed way (each component, GW, TM, KM are running in their own Docker image) on top on DC/OS 1.9 ( Mesos ).
We have issues to get the gateway to enforce throttling policies (should it be subscription tiers or app-level policies). Here is what we have managed to define so far:
The Traffic Manager itself does it job : it receives the event streams, analyzes them on the fly and pushes an event onto the JMS topic throttledata
The Gateway reads the message properly.
So basically we have discarded a communication issue.
However we found two potential issues:
In the event which is pushed to the TM component, the value of the appTenant is null (instead of carbon.super)- We have a single tenant defined.
When the gateway receives the throttling message, it decides to let the message go thinking the "stopOnQuotaReach" is set to false, when it is set to true (we checked the value in the database).
Digging into the source code, we related those two issues to a single source: the value for both values above are read from the authContext and apparently incorrectly set. We are stuck and running out of ideas of things to try and would need some pointers to what could be a potential source of the problem and things to check.
Can somebody help please ?
Thanks- Isabelle.
Is there two TM with HA enabled available in the system?
If the TM is HA enabled, how gateways publish data to TM. Is it load balanced data publishing or failover data publishing to the TMs?
Did you follow below articles to configure the environment with respect to your deployment?
http://wso2.com/library/articles/2016/10/article-scalable-traffic-manager-deployment-patterns-for-wso2-api-manager-part-1/
http://wso2.com/library/articles/2016/10/article-scalable-traffic-manager-deployment-patterns-for-wso2-api-manager-part-2/
Is throttling completely not working in your environment?
Have you noticed any JMS connection related logs in gateways nodes?
In these tests, we have disabled HA to avoid possible complications. Neither subscription nor app throttling policies are working, both because parameters that should have values have not the adequate value (appTenant, stopOnQuotaReach).
Our scenario is far more basic. If we go with one instance of each component, it fails as Isabelle described. And the only thing we know is that both parameters come from the Authentication Context.
Thank you!
I have create wso2 human task where the approval has to be given by multiple owners in parallely. I am calling human task from Synchronous BPEL process. I am able to upload the Process and task packages successfully. But only one potential owner get approval not others.This link said BPS 3.2.0 Routing Patterns are not supported.WSO2 BPS 3.2 human task assignment to multiple people creating Process in failed status
So I put this this in my code.
<htd:potentialOwners> <htd:from>htd:getInput("ClaimApprovalRequest")/test10:UserList/test10:ME</htd:from>
</htd:potentialOwners>
<htd:potentialOwners> <htd:from>htd:getInput("ClaimApprovalRequest")/test10:UserList/test10:HBR</htd:from>
</htd:potentialOwners>
''
Any idea what is going wrong here. As the task creation is working fine.
To clarify what you are doing now: when you assign to potentialOwners, that means that any one of the people in that group can complete the task. That is not the same as: all people have to carry out the task.
What you probably want, is:
<htd:potentialOwners><htd:parallel type="all">...owners...</htd:parallel><htd:potentialOwners>
I do not know if WSO2 supports that though.
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.
