 It's looks like POM is invalid due to undefined properties such as

since we are almost done with our setup and would be great to point it to

 Hi All,



 This is the summary of everything that I have done so far.



 Pre requisite: VMs which has WSO2 Application Server running should
 have been added to a particular network security group (NSG). In my case
 it’s ASNSG



 First the java app should be authenticated. Then it query for the
 information on ASNSG. Response of that API call includes names of all the
 network interfaces that are existed in ASNSG. Then each and every network
 interface is queried using their names to get private IP addresses of each
 of them. As the final outcome we get a list of IP addresses of VMs which
 has WSO2 Application Server running.



 *Authentication*

 In order to work with Azure Resource Manager (ARM) REST API, first of
 all our app has to be authenticated. ARM provides two methods for this
 purpose,



 1) Authenticate using service principal

 2) Authenticate using organizational account.



 I have used the first method that is authenticating using a service
 principal.  A Service Principal is an instance of an application that is
 within your Active Directory that is allowed access to one or more
 resources or an entire resource group. How to set up a service principal is
 well described here [1]. Once you successfully set up a service principal,
 you will have the following information in hand.



 1)  Client ID

 2)  Client secret

 3)  Tenant ID

 Above parameters and Azure subscription ID are used in the java app for
 authentication purpose. I have used Active Directory Authentication Library
 (ADAL) [2] for authentication. Once the authentication is successful, an
 authentication token will be issued and it will be used in the rest of the
 program as to make calls to API.



 *Getting information on ASNSG*

 For this purpose, [3] API reference is used. As the response we get a
 JSON string which includes names of NICs which are available in ASNSG.



 *Getting private IP address of each NIC*

 With the NIC names we received from previous API call, we can use this
 [4] API reference to get the private IP address of each NIC. And then with
 that information we can list out the IP addresses of all the VMs which has
 WSO2 Application Server running.

 Hi mentors,



 Sorry for the late reply. ARM portal doesn't have certain features like
 Active Directory but it doesn't matter because they can be implemented
 using classic portal and they work hand in hand. So all the features in
 classic plus the new features in ARM can be used if we choose ARM model.
 Therefore I think it's fruitful if we stick to ARM model, and the other
 important thing

[Dev] [Documentation] [APIM] Where is "API Usage By User"

[Amila Maha Arachchi]

Doc and APIM Team,

I can see a screenshot in [1] for "API Usage By User". But, AFAIU, it is
not there anymore in the API Publisher's statistics menu.

I have seen users getting confused over this [2].

Please fix the docs.

[Dev] Is there a feature that bundles common-scxml?

[Amila De Silva]

Hi,

Need to know if there's a feature that bundles common-scxml.
In all the instances where this bundle has been used, it had been included
as a bundleDef in a product specific feature. But if there's a feature for
this bundle, we could have directly imported the feature rather than
including the bundle in non-related features.

Re: [Dev] [IS] Define the default authenticator/sequence to use a custom federated authenticator

[Darshana Gunawardana]

Also there are few complications when configuring federated scenario for a
file based service provider. Following JIRA has more information.

https://wso2.org/jira/browse/IDENTITY-4581

For an elegant solution, it should fix above JIRA first. Otherwise you will
be endup with duplicating the full IdP configuration inside the service
provider config.

Re: [Dev] [IS] Define the default authenticator/sequence to use a custom federated authenticator

[Darshana Gunawardana]

Hi Farasath,

It seems like my assumption is wrong. As per the code [1] doesn't read from
application-authentication.xml to read default behaviour. It is reading
from default service provider file
(/conf/identity/service-providers/default.xml). IMO this is a bug, it need
to pick that behaviour from the application-authentication.xml.

[Dev] Fwd: Fwd: GSOC2016: [ML][CEP] Predictive analytic with online data for WSO2 Machine Learner

[Mahesh Dananjaya]

Hi maheshakay,
I have implemented the linear regression with cep siddhi event stream with
taking batch sizes as parameters from the cep. Now we can trying the moving
window method to. Before that i think i should get your opinion on data
structures to save the streaming data.please check my repo [1]  /gsoc/
folder there you can find all new things i add.. there in the extension
folder you can find those extension. And i will be able to send you the
timing/performances analysis report tomorrow for the SGD functions. thank
you.

Mahesh.

 Hi Mahesh,

 As we discussed offline, we can use similar mechanism to train linear
 regression models, logistic regression models and k-means clustering 
 models.

 As we have to train predictive models with Spark, you can write
 wrappers around regression/clustering models of Spark. Refer to Siddhi time
 series regression source codes[1][2]. You can write a streaming linear
 regression class for ML in a similar fashion by wrapping Spark mllib
 implementations. You can use the methods "addEvent", "removeEvent", etc.
 (may have to be changed according to requirements) for the similar purpose.
 You can introduce trainLinearRegression/LogisticRegression/Kmeans which
 does a similar thing as in createLinearRegression in those time series
 functions. In the processData method you can use Spark mllib classes to
 actually train models and return the model weights, evaluation metrics. So,
 converting streams into RDDs and retrieving information from the trained
 models shall happen in this method.

 In the stream processor extension example, you can retrieve those
 values then use them to train new models with new batches. Weights/cluster
 centers maybe passed as initialization parameters for the wrappers.

 Please note that we have to figure out the best siddhi extension type
 for this process. In the siddhi query, we define batch size, type of
 algorithm and number of features (there can be more). After batch size
 number of events received, train a model and save parameters, return
 evaluation metric. With the next batch, retrain the model initialized with
 previously learned parameters.

 We also may need to test the same scenario with a moving window, but I
 suspect that that approach may become so slow as a model is trained each
 time an event is received. So, we may have to change the number of slots
 the moving window moves at a time (eg: not one by one, but ten by ten).

 Once this is 

[Dev] [IS] Define the default authenticator/sequence to use a custom federated authenticator

[Farasath Ahamed]

Hi All,

When trying to set the "*Local & Outbound Authentication Configuration*"
for a Service Provider I noticed a default option. If someone wants to use
a custom/federated authenticator as the default option how can we achieve
this?

Based on a discussion with Darshana, I tried to achieve this by modifying
the default sequence in application-authentication.xml file found at
IS_HOME/repository/conf/identity as below,










Even then I am redirected to use the default BasicAuthenticator (username
and password). Are there any other changes that need to be done to engage a
federated/custom authenticator as the default throughout IS?

Re: [Dev] clarification on api publisher on summary tables

[Rukshan Premathunga]

Hi all,

Still we are publishing API creator for API publisher field for all the
event streams. Even in registry, API publisher is not maintain and only
creator field is updated. So can we continue with this behavior or do we
need to any changes to the event stream?

any suggestions?
