Re: [Dev] [CEP] How to write a Siddhi query to get the total count from an Event Table

[Supun Muthutantrige]

Hi seshika,

Yes tried that but it doesn't give the desired output.

The query that we have used as follows,

from forCalculation#window.length(1) join MarkovModel
on forCalculation.initialState == MarkovModel.Initial_state
select initialState as Event, sum(MarkovModel.countP) as totalCount
insert into ckStream;

this was tried using group by as well, Still it doesn't give the result

any thoughts?

Thank you
Regards

Re: [Dev] [CEP] How to write a Siddhi query to get the total count from an Event Table

[Seshika Fernando]

Hi Shashika,

I don't think the count() function will work here. They need a sum of the
values in the countP field. Therefore, they will have to use sum(countP).
So for Initial state HTS, count() will give 2 while sum() will give 4.

I think I have used the wrong field name in my previous email. Sorry about
that.

Re: [Dev] [CEP] How to write a Siddhi query to get the total count from an Event Table

[Shashika Karunatilaka]

HI supun,
you can use the count function and grouping it by Initial_state(group by
Initial_state)

Thanks

Why dont you use the sum(Initial_state) function with a group by
Initial_state?

[Dev] [CEP] How to write a Siddhi query to get the total count from an Event Table

[Supun Muthutantrige]

Hii all,

There is a mysql table with the following content.


The format of the in stream

   state:HTS
   state:HFS
   state:HTM
   state:HTS
   state:HTL
   state:HFS
   state:MTS
   state:HTS
   state:HTL
   state:MFM
   state:HTS
   state:HFS​


The following siddhi query is used to populate the above table.

--

define table MarkovModel (State_Transition string, Initial_state string,
countP double) from ('datasource.name'='FD_ToolBox_DB',
'database.name'='FDtoolbox',
'table.name'='MarkovModel');

from every a = inStream -> b = inStream
select a.Event as initialState, b.Event as transState,
concat(a.Event,b.Event) as StateTransition
insert into forCalculation;

from forCalculation[((StateTransition!=MarkovModel.State_Transition)
in MarkovModel)]
select StateTransition, initialState, 1.0 as stateTrans_count
insert into insertIntoModel;


from forCalculation[((StateTransition==MarkovModel.State_Transition) in
MarkovModel)]#window.length(1) join MarkovModel
on forCalculation.StateTransition == MarkovModel.State_Transition
select StateTransition, initialState, (MarkovModel.countP+1) as
updatedState_count
insert into updateModel;

--

Want to know how get the total count of *Initial_state*'s from the above
table as a continuation to the above query.

Ex: HFS - 2
  HTL - 2
  HTM - 1
  HTS - 4
  MFM - 1
  MTS - 1

Would appreciate any suggestions.

Thank you
Regards

 Hi Danuska/All,

 Since these all bundled with Ubuntu, We may suggest Mac OS users to
 manually install all these tools and use the puppet without any changes,
 Then the code would be as below.

 $packages = ['lsof','unzip','sysstat','telnet', 'git', 'less', 'tree', 
 'zip']

 package { $packages:
   ensure => installed,

[Dev] [Carbon] Implications of Hostname verification set to AllowAll in HTTPS?

[Niranda Perera]

Hi carbon team,

This is based on a WSO2 customer query.

While using APIM with a custom host name, the following error occurred.

2014-11-11 09:12:09,794 [-] [HTTPS-Sender I/O dispatcher-1] ERROR
TargetHandler I/O error: Host name verification failed for host :

org.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor$Worker.run(AbstractMultiworkerIOReactor.java:604)

at java.lang.Thread.run(Thread.java:745)

This was RESOLVED by modifying the HostnameVerifier parameter of the
 element to 'AllowAll'.

But I have the following quesitons.
1. In a production environment, is it a good practice for making
HostnameVerifier AllowAll?
2. What are the implications of making HostnameVerifier AllowAll?
3. Is there any other way to handle this rather than verifying all the
hostnames by default??

Look forward to hearing from you.

Cheers
Rgds

Re: [Dev] Errors in Documentation of WSO2 ESB 4.8.1

[Nisrin Sheriff]

Hi Farasath,

With regard to https://wso2.org/jira/browse/DOCUMENTATION-1279:

In older versions of the ESB documentation we did give instructions on
installing third party software like ActiveMQ.

We do not provide this information in the latest ESB documentation because
you can find this information when you go to the ActiveMQ download link
given in https://docs.wso2.com/display/ESB481/Installation+Prerequisites.

We only provide instructions on configuring WSO2 ESB with ActiveMQ.

Therefore, I have specified this and resolved the JIRA issue.

Re: [Dev] HTTP Patch support by ESB 4.8.1

[Malaka Silva]

Hi Ushani,

Thx for the info.

Can you please let us know the exact issue?

Is it related to HTTP Patch support by ESB 4.8.1?

or JSON issues in script mediator?

Best Regards,
Malaka

 Agreed with Miyuru. however this is experienced ONLY on WSO2
 environment. but not in our local environments.  that's why no idea what is
 the cause. however i have noted this only cause when we use java script
 mediator. appriciate any idea to solve this as few integration testing
 onhold due to this un identified issue :)

 Hi,

 Both BAM and DSS are added to chunk-13. Yesterday there was some issues
 found in the built BAM pack during smoke test. Maninda will be able to give

Re: [Dev] Writing a CEP extension to receive a video or image

[Srinath Perera]

Then should he write an input adapter instead of an extensions and only
handle higher level events in Siddhi?

I am OK for that approach!

 Hi Suho, Mohan,

 Open CV (computer vision library) let you train and build a model that
 generates an XML file that can be used from a java program to classify
 video streams (e.g. detect an human, vehicle).

 Idea of the project is to write an CEP extension that takes the XML
 file and detect vision detection. We can send each frame in video as an
 event. However, it is a byte array. How can we send this? If he used
 siddhi, can he send it by defining type as object?

 Long term we should define an byte[]

[Dev] How to restrict accessing web application

[Danesh Kuruppu]

Hi all,

I am currently working on upgrading the solr in registry indexing. with the
proposed design, we are going to deploy solr webapp in the carbon server
and use it for registry indexing and we need to allow accessing solr web
app only for admin users.

What is the best way I could follow to restrict the web app access in
carbon server.

Thanks

[Dev] Distributed setup BAM 250 - Erorr "java.lang.NoClassDefFoundError: org/wso2/carbon/stratos/common/listeners/TenantMgtListener"

[Sewmini Jayaweera]

Hi,

I am trying to set up a distributed set up locally using 2 BAM packs having
analyser, receiver and Hadoop running on one pack and cassandra on the
other pack.

when i start cassandra node it successfully starts.  But when I try to
start BAM using './wso2server.sh -Dsetup' I get an exception as mentioned
below. furthermore I have attached the configurations steps and full error
logs. Highly appreciate it if someone help me with this issue.

Error

 Hi all,

 This is regarding the Fast Track Training Project that I selected to
 complete [1].

 The task is to create a CEP extension which will receive a stream of
 video and do several image processing tasks to identify an object.

 Need to know more insight on how to send input a video stream.

 Even though it is a video, we can use it frames. Which will be a set of
 images.

Re: [Dev] Writing a CEP extension to receive a video or image

[Srinath Perera]

Hi Maninda,

I agree with the concern.

However, as far as the Hemika's project is concerned, lets accept that
inefficiency to keep it within 3 weeks scope.

Having said that, I am very much interested how video stream like data set
can be received and processed though an event stream (within Siddhi). May
be the best we can do is to process them at an input adapter and only send
high level events. If you understand this domain, can we chat about this a
bit.

Re: [Dev] Accessing a DB through bundle starter

This could well be an issue with the bundle start up order. However, have
we tried putting a few logs in ndatasource bundle activator too and made
sure that this really is the reason why the JNDI look-up failed?

On a side note, I'm seeing you guys've extended "BundleActivator" to
implement the bundle initializer. I'd recommend you guys follow the
"Service Component" approach where it is purely declarative and much
appropriate for implementations that require access to a lot of external
declarative service dependencies, which is quite common across most of the
components we've got in the platform. Not only that, the former is
generally considered an "old" approach of activating a bundle, which could,
however, be used if you need to get hold of some of the very lower level
controls of the bundle activation process. There's a quite a few other
advantages too like being able to define more than one Service Components
within an OSGi bundle etc, but IMO, this is not quite needed in most of the
cases we often tend to deal with, within the platform.

Cheers,
Prabath

[Dev] [CEP] Failed to access registry when CEP starts

[Madhawa Gunasekara]

Hi All,

We have written two CEP extensions to load a model from the registry using
WS-API,  transformer and function. Our extensions work fine when CEP is in
a stable mode.
but after CEP restarts CEP tries to execute our extensions in its beginning
state. at that time registry was refusing our request. due to that reason
we got this following error,but Registry was available at that time.

   - ERROR - {EventProcessorDeployer}  Execution plan is not deployed and
   in inactive state : NERExecutionPlan.xml
   
org.wso2.carbon.event.processor.core.exception.ExecutionPlanConfigurationException:
   Invalid query specified, java.net.ConnectException: Connection refused

This error occurs only for one execution plan (NERExecutionPlan) which we
used our transformer. Other execution plan (ClassifyingExecutionPlan)
perfectly works in the beginning state also. both extensions are using
models from the registry.

We have tried threads but it didn't work.we hold the Extension thread till
another thread reconnects to the registry and pass the file. then CEP
didn't start properly :(
if we release the Extension thread, then file not be loaded.
Is there any proper way to solve this?

We load models in the init method. As per my understanding CEP execute init
methods in the beginning state. If we load models in processEvent method we
can neglect these errors. but It's not a proper way.

Please how can we figure out this.
Please find the attached error messages and execution plans files.



Thanks,
Madhawa

Re: [Dev] Getting error in puppet integration to Mac OS X during tools installation using 'brew'

[Imesh Gunaratne]

Hi Rajeevan,

Can you please explain your goal bit further? Are you trying to setup an
AppFactory development environment using puppet on OS X?

If so it might not be ideal, better to use VMs or containers due to many
reasons:
- A desired OS can be used.
- Provides OS level isolation for each server.
- Entire environment can be wiped away and repeated without affecting the
host OS.
- Puppet may bring in an overhead.

At the present the most widely used tool for this purpose is Vagrant. A
simple Vagrant script could bring up an entire software stack in number of
hosts in minutes (depending on how software is installed).

Thanks

 Hi Danushka,

 I don't think having a puppet master for Mac is a good option. Then in
 future you will have to have puppet masters for every platform which is not
 maintainable friendly. A change would have to duplicate in every where.
 Having a single puppet master for each environment must be the
 recommended approach.



 Touched, not typed. Erroneous words are a feature, not a typo.

Re: [Dev] Writing a CEP extension to receive a video or image

[Maninda Edirisooriya]

In general video streams are compressed in time domain. If we send one
frame as an event this will not be achieved and the required bandwidth will
be higher.
Instead if the video stream can be chunked and decompress inside the server
/ engine, bandwidth could have been saved.

BTW we can use the same input adaptors to get videos to BAM and do some
batch processing if map-reduce implementations can be found for computer
vision algorithms like http://hipi.cs.virginia.edu/

[Dev] Accessing a DB through bundle starter

[Lochana Menikarachchi]

Is it possible access a database within osgi bundle's start method?

public void start(BundleContext context) throws Exception {
ModelService modelService = new ModelService();
context.registerService(ModelService.class.getName(),
modelService, null);

* MLAlgorithmConfiguration mlAlgorithmConfiguration = new
MLAlgorithmConfiguration();
mlAlgorithmConfiguration.loadMLAlgorithmConfigurations();*
logger.info("Model service started");
}

loadMLConfigurations loads some default values to a database. Adding bold
lettered lines throws following exception

INFO {org.wso2.carbon.ml.dataset.DatasetServiceActivator} -  Dataset
service started

 Is there other things that breaks?

 If answers are yes and no the I would be fine with installing it
 manually for first time for mac since this is just dev setup.
 @Dimuthu : WDYT?

 But if it is not the case then we may need to have separate puppet
 master for mac. [1]

Re: [Dev] Getting error in puppet integration to Mac OS X during tools installation using 'brew'

[Aiyadurai Rajeevan]

Hi All,

The above option doesn't resolve the issue, Even though i managed to find a
solution suggested in [1] . But this solution leads to maintainability
issues as highlighted by Udara.

Hence we are trying to achieve this using docker.

@Sajith - Referring to STRATOS-776
 issue which was raised
regarding Stratos image is not starting, As per the comments it will be
fixed in 4.1.0-M2.  Is it possible to align the fix in 4.0.0?

 Hi All,

 We are in the process of integrating puppet scripts to Mac OS X, Where
 we have implementation to install list of tools to be installed by puppet
 script when executed, The puppet code looks like below.

 *$packages = ['lsof','unzip','sysstat','telnet', 'git', 'less', 'tree',
 'zip']*

 * package { $packages:*

  *ensure => installed,*

 *provider  => 'brew',*

 *}*


 Here, *$Packages* has the tools to be installed using the *brew*.

 When i execute this, it gives error as below,

 *Error: Failed to apply catalog: Parameter provider failed on
 Package[lsof]: Invalid package provider 'brew' at
 /home/rajeevan/appfactory/modules/wso2base/manifests/packages.pp:9*

 *Wrapped exception:*

 *Invalid package provider 'brew'*

 *Wrapped exception:*

 *Invalid package provider 'brew'*


 Then we executed the command - *brew install unzip* - just to ensure
 the unzip tool is getting installed, but it doesn't.

 google it and found a solution [1]

 *$ brew tap homebrew/dupes *

 *$ brew install unzip*

 This works nicely,

 But, As far as puppet concerned, How to do this in my above puppet
 script?

 Appreciate your view on this please.
