In WSO2 documentation we get reference of a capacity planning sheet. (http://wso2.com/library/articles/2015/12/article-capacity-planning-exercise-with-wso2-middleware-platform/)
How can we as developers get this sheet and do capacity planning for ESB implementation? Is it getting newly introduced in the Application stack?

I have already read many documentations of WSO2, there are some products of WSO2 such as: Enterprise Integration (EI), API Management (APIM), Identity Access Management (IS), Analytics Stream Processing (SP). I can understand the functions of IS and SP.
1. But I dont know what are differences between EI and APIM?
2. When can we use EI? When can we use APIM?
3. Can we merge WSO2 EI and APIM and IS and SP Products to execute all of them on one server?
Sorry for many questions, but I am really confuse in these matters, please give me advice.
WSO2 EI can be used to integrate different systems, orchestrate and then expose as new services/APIs.
WSO2 APIM can be used to manage those services/APIs. You can manage security, rate limiting, CORS, etc. and can see analytics of API usage etc. too. For APIM analytics, there is a customized version of SP which you can download separately.
You can't run all 4 as a single server. Those are 4 runtimes, so you have to start them separately.
I am currently using WSO2 DSS to create RESTful APIs to access the databases.
I need DSS to perform OAuth authentication for every incoming request. Is there a way I can do it without using WSO2 API Manager or WSO2 ESB?
If I have to change the source code to implement this feature, which particular library should I be looking into?
For this scenario without using WSO2 API Manager you need use three products of WSO2 SOA Suite (ESB, IS, DSS). In other case you can add the WSO2 DSS as a feature to the WSO2 ESB, and use IS as key manager. Check this links and take your best decision.

I am trying to access the registry of WSO2 BPS and WSO2 ESB from Java in order to automatically fill the registry based on the data I provide.
I have already found a number of resources about the required Java code and dependencies, this being the most helpful one: [WSO2 Governance Registry]Using WSRegistryServiceClient. However, the approach described in these resources depends on the WSRegistryService service. This service is included in Governance Registry by default, but not in the other WSO2 products. I have verified that my code works for the Governance Registry. For any other WSO2 product on my machine, I get this error:
The service cannot be found for the endpoint reference (EPR) https://localhost:9445/services/WSRegistryService
I found an old thread suggesting that it should be possible to install the WSRegistryService on other WSO2 products as well, but I have not been able to find out how to do so. I can't seem to find it within the features I can install from the web console of the products. I have also tried manually copying the relevant jar from the plugins directory of Governance Registry into the plugins directory of other products, but that doesn't seem to be sufficient.
Note that my application for filling the registry will not be running on the carbon server whose registry I want to access, so using CarbonContext.getThreadLocalCarbonContext() (an approach I found in some other articles) is not an option.
I think your referring to how to install features to WSO2 products,
Please find this documentation.
I have a working system with ESB (non-WSO2 product) already. I'm now trying to integrateWSO2 API Manager into my working system for 3rd party developer.
Is it possible to replace WSO2 ESB in API Manage with existing non-WSO2 ESB?
Yes, you can do that.
The ESB functionality is transparent no matter what is the brand of underlying product implementing it. The API Manager is going to store the endpoints, WSDLs, etc. and those are the same for every ESB implementation.
That's the "beauty" of SOA, its service-oriented, not vendor-oriented.
You can keep the ESB you are using as it is in your setup and use the API Manager to publish/subscribe/manage the API. Its perfectly a valid scenario

I am creation Gadget for WSO2 BAM dashboard. I need to add the data to the chart that gives service of monitored server as result. How can I make this data as values of charts?
The standard way to follow is,
You need to first expose this data through a service. Ex: Can be done through a data service with WSO2 DSS, a back end carbon component on top of WSO2 Carbon, or just any web service
Then, write a gadget to consume this service. Reference: gadget tutorial
PS. There is a new BAM that will make all these things extremely easy, without having to write code. It should be available towards the end of the year.
You can use the BAM2 alpha2 available in here for generating gadgets according to your requirement. It is now much easier to generate a gadget with drag and drop gadget IDE comes with BAM2.
You can find more information from documentation
This is available using GadgetGen tool feature under latest BAM version
