[cosmos-dev] defining SML resources for data collection and manageable a

[Valentina Popescu <popescu@xxxxxxxxxx>]

Hi everybody

I have created a first draft of the
SML definitions for describing data controllers and data collection agents.
Comments and suggestions are appreciated.


The following information is logged
into the bugzilla enhancement below. 

https://bugs.eclipse.org/bugs/show_bug.cgi?id=178590



I have created definitions for a data
controller and a data collection agent; see attached zip.


The zip file contains:
1.      dataController.xsd
 
A common definition for a controller
routine; the controller has references to a set of agents, defined by the
managedAgent.xsd. It also contains a configuration facet and a definition
facet. 
Since the controller extends by restriction
a generic item type, any controller can only have these three type of facets
: definition , configuration, agents list. 
The controller can be customized though
through the predefined facets. So although the content of acontroller is
static, the configuration facet can be extended to contain ANY type of
properties.  In a similar way, the definition facet can be extended
to contain more then just the predefined properties.

A sample of the controller usage is
under the tptpDataController.xsd/xml

2.      managedAgent.xsd
A managed agent is a routine that can
be controlled by a data controller and can collect data.
The agent type is extended by restriction
from the basic item type and has a predefined set of facets.
Similar with the controller type, it
has 
-       a definition
facet ( extendable to add new properties ).
-       A configuration
facet – extendable to add new properties
-       A source data
facet; it has the following properties - extendable:
A source type ( file, db, etc )
A source location property – describe
how to get the agent input data
A description 

A sample of the agent usage is under
the apacheErrorLogAgent.xml and statisticalAgent.xml

I am in the process of validating these
types by defining more agents/controllers so more than likely this is not
the final version. I would appreciate if you review and comment on the
current version. 


A short introduction of the terms I
am using, which are defined in the Data Center SML model under the item.xsd
file :
1.      item - is the
base type for any SML root object. An item can have a
collection of facets
2.      facet – is a
generic grouping that can contain collections of
properties, facets or facet references

3.      property – a
base type for a generic property
