Re: Simple Indication Provider

Diogo,

Pegasus does not support lifecycle indications implicitly, its providers 
responsibility to generate the instance lifecyle indications. Since the 
provider was registered for the class CIM_ConnectivityCollection, and 
indication filter query class name specified was CIM_InstModification, 
Pegasus tries find the providers for CIM_InstModification class hierarchy. 
Create one more capability instance for CIM_InstModification (preferably 
its derived class) class and update the provider to handle the new class 
and generate indications. Usually generic CIM classes are not directly 
instrumented by the provider instead derived classes are instrumented.

Thanks Paul,

I'm using Ubuntu 10.10. 

I wrote the mof file for the indication provider and it goes like this:

instance of PG_ProviderModule
{
    Description = "Experimental Pegasus Indication Provider Module that 
implements some class";
    Caption = "Experimental Pegasus Indication Provider Module";
    Name = "XPTOIndicationProviderModule";
    Vendor = "OpenPegasus";
    Version = "2.0.0";
    InterfaceType = "C++Default";
    InterfaceVersion = "2.2.0";
    Location = "XPTOIndicationProvider";
};

instance of PG_Provider
{
    ProviderModuleName = "XPTOIndicationProviderModule";
    Name = "XPTOIndicationProvider";
};

instance of PG_ProviderCapabilities
{
    ProviderModuleName = "XPTOIndicationProviderModule";
    ProviderName = "XPTOIndicationProvider";
    CapabilityID = "XPTOIndicationProvider-01";
    ClassName = "CIM_ConnectivityCollection";
    Namespaces = { "root/cimv2" };
    ProviderType = { 4, 5 };  // Indication & Method
};

So I want to receive indications related the CIM_ConnectivityCollection, 
ConnectivityStatus up or down.

For that I create an instance of CIM_IPConnectivitySubnet:

$ cimcli ci -n root/cimv2 CIM_IPConnectivitySubnet ElementName="subNet101" 

InstanceID="subNet1010" ConnectivityStatus=2 SubnetNumber="10.10.10.0" 
SubnetMask="0.0.0.255" AddressType="1"


So whenever that connectivity status is changed a indication is received, 
right!!!

Next I created the filter & handler instances:

$ cimcli ci -n root/cimv2 CIM_IndicationFilter 
CreationClassName=CIM_IndicationFilter Name=TestFilter Query="SELECT * 
FROM 
CIM_InstModification" QueryLanguage=WQL

I have to query the CIM_InstModification, right?

$ cimcli ci -n root/cimv2 CIM_ListenerDestinationCIMXML 
CreationClassName=CIM_ListenerDestinationCIMXML Name=TestHandler 
Destination="http://localhost:5999/Eventlogs"

when I try to create the CIM_IndicationSubscription:

$ cimcli ci -n root/cimv2 -v CIM_IndicationSubscription 
Filter=CIM_IndicationFilter.CreationClassName=\"CIM_IndicationFilter\",Name=\"Te
stFilter\",SystemCreationClassName=\"CIM_ComputerSystem\",SystemName=\"ubuntu\" 

Handler=CIM_ListenerDestinationCIMXML.CreationClassName=\"CIM_ListenerDestinatio
nCIMXML\",Name=\"TestHandler\",SystemCreationClassName=\"CIM_ComputerSystem\",Sy
stemName=\"ubuntu\"

I get:

cimcli CIMException:  Cmd= ci Object= CIM_IndicationSubscription Code= 7
CIM_ERR_NOT_SUPPORTED: No providers are capable of servicing the 
subscription.


Any hints that could help? 

Thanks.
