How to construct the Resource URI when i have my own CIM class

[mhsundar]

Hello All

I am a beginner in openWSMAN. I would like to know, how to construct the Resource URI when i have my own CIM class. I have extended the CIM_ComputerSystem to create my own class, called TEST_ComputerSystem. I have also written the CMPI provider for my TEST_ComputerSystem Class.

When I enumerate instances of my class through wsman by giving,

wsman enumerate http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/TEST_ComputerSystem

i get the error saying,


<?xml version="1.0" encoding="UTF-8"?>

  </s:Body>
</s:Envelope>
Connection failed. response code = 400


But when i use the filter option, like

wsman enumerate http://schemas.dmtf.org/wbem/wscim/1/* --filter "select * from TEST_ComputerSystem"

i could able to get the result.


My question here is, for my own defined class, how do i get my instance with out using the --filter option. How should i construct my resource URI?

Thanks

The URI prefix (http://schemas.dmtf.org) is for the CIM base classes.
So it doesn't match your own class.

Here you're enumerating all CIM base classes _and_ its derivates.
Hence you also get your class (derived from CIM_ComputerSystem)

You have to register your own namespace as "vendor_namespaces" in
/etc/openwsman/openwsman.conf using the class prefix.
So add something like
TEST=http://mhsundar.gmail.com/my/test
to the "vendor_namespaces=" line and then call wsman with

 wsman enumerate http://mhsundar.gmail.com/TEST_ComputerSystem

Thanks a lot Mr. Klaus. Now i could understand the issue.

But how do i define my namespace?.

I have a CIMOM server running on my localhost and i have created a namespace
called "root/test". So in this case, will my vendor namespace be "http://localhost/root/test"?

Can u please clarify?

Thanks

For openwsman, its just a URL. I am not aware of any other rules or
limitations.
You might want to look at the namespaces listed as vendor_namespaces
in openwsman.conf, most of them have digits in their path denoting a
specific version. That's probably most useful.

Be careful not to mix wsman namespaces with CIM class namespaces.
Wsman namespaces look like a URL (http://....) while CIM namespaces
look like a path (foo/bar).

I am also encountering this issue and hoping to get a little more clarification. In your example you used : http://mhsundar.gmail.com/my/test, but how do we know what to put after the http://. I am still just unsure of how to construct the actual URL.

If I remember things correctly, the resource URL passed to openwsman is divided into two parts actually. The first part is what we define in "vendor_namespaces" section and the other is CIM class name.
For example, if we define "TEST=http://mhsundar.gmail.com/my/test" in "vendor_namespaces" section,  "http://mhsundar.gmail.com/my/test/TEST_ComputerSystem" is a valid URL and "http://mhsundar.gmail.com/my/test/Linux_ComputerSystem" is not. That is to say, if you want to make your CIM class names recognized in openwsman, register the prefixes of the CIM class name with their corresponding URLs.

If we have a custom provider how do we determine the vendor_namespace then? Thanks for the help

I think it depends on you. Anything unique is OK, although it is often
some kind of vendor URL.
