CIM/SMASH has lots of properties that return 'None'
Hope this is the correct place to post. When I clicked on the "CIM/SMASH SD"K forum link this is where it led. If there is a better place, please let me know.
I have just installed vSphere on a test system to start developing some management apps. Using CIM/SMASH, the first thing we were looking for was to get processor load percentage. CIM_Processor (per physical processor) and CIM_ProcessorCore (per core) each have a "LoadPercentage" property. Perfect. But the included output is what I get (dual core system). The 'LoadPercentage' property is None. If it were '0' I would understand, but it looks like the CIMOM is not providing the value. I understand if there is not hardware instrumentation provided by the vendor why some values would be missing, but LoadPercentage is an OS (ESXi) function.
Could someone please shed some light on this for me?
Thanks

Here is the result of using the Perl SDK to retrieve CPU metrics from the same machine (viperformance.pl). Unless a VMware employee answers concretely, I assume CIM/SMASH has bugs.
We are doing an evaluation and this does not give me faith. Either there is really a problem or the documentation is lacking.
Anyone?

Not sure anyone cares, but further testing has revealed the following. I created a 2 core VM on a 4 core host and ran code so each CPU was 100% utilized. The vSphere client correctly showed cpu "Usage" (all cores) as around 50% as expected.
- The SNMP values from hrProcessorLoad in the HOST-RESOURCES-MIB are inaccurate. http://sourceforge.net/tracker/index.php?func=detail&aid=635348&group_id=12694&atid=112694 It appears that this has been a bug for 10 years that is never going to be addressed.
- I have verified that the CIM/SMASH API does not support the CIM_RegisteredProfile profiles that the documentation says it does, and that can be enumerated with a WBEM client. As seen in my first post, over half the properties are empty, making VMware's claim that vSphere 5 is CIM/SMASH a bit of a joke.
- Which leaves the SOAP API. Yes, it works. But it's very slow and very heavy if all you want to is pull a couple of resource metrics from the host.
We are running an evaluation of vSphere and I have spent days reading and following the vSphere management SDK documentation. I am not very happy with the complex SOAP API, but at least if I had known that the other published and documented APIs were dead-ends I wouldn't have wasted 3 days.
I tend to read docs and dig in, and I don't mind doing it. But I expect the documentation to be accurate.
I hope this isn't indicative of the level of documentation and support for VMware's product portfolio.
Obviously, I am not expecting a response on this forum.
