I'm currently working to build a SBLIM CIM client that communicates with CIM Server (OpenPegasus).

The goal of the client is to obtain performance data from the Server. I was able to enumerate instances for CIM_OperatingSystem and CIM_UnixProcess but not for CIM_BaseMetricValue.

Here is the basic enumeration code:
Namespace = root/cimv2
Classname = CIM_BaseMetricValue


final CloseableIterator<CIMInstance> iterator = pClient.enumerateInstances(
new CIMObjectPath(null, null, null, pNamespace, pClassName, null), true, false,
false, null);
try {
final List<CIMInstance> result = new ArrayList<CIMInstance>();
while (iterator.hasNext()) {
final CIMInstance instance = iterator.next();
result.add(instance);
System.out.println(toMof(instance));
}


The return value of the iterator is Null for classname = CIM_BaseMetricValue.

The result is same even for CIM_BaseMetricDefinition class.


Here are some more details:

# cimprovider --version

# cimprovider -ls

The gatherer and repository are up and sampling:
# gatherctl
s
Status initialized and sampling, 6 plugins and 20 metrics.
q
# reposctl
s
Status initialized, 6 plugins and 69 metrics.

So, if the provider is up and running, then why aren't there any instances of the CIM_BaseMetricValue, Definition?
Any help in this regard is very much appreciated. I spent more than two week trying to figure what I’m doing wrong, but made no progress.


Thanks in advance,
