Unfortunatly, we haven't been able to find a MOF/provider thatis able to do this for us. So we decided to write our own.We want to use Cimbiote for this. The example you wrote (example_plugin.py)is pretty clear, except for the methods. I believe there are tho methods, set and get_array_element, and they both require some args. I am trying to access the method using this command: # wbemcli cm 'http://localhost/root/cimv2:ExamplePlugin.Filename="file-9.txt";' get_array_elementThis returns "a general error occured, not covered by more specific code", and I should check some logs. I have tried various options for the method invocation, but I never get a valid response. Can you give me an example ofhow to execute this method?

You're basically the first person who has asked about it. Cimbiote is now largely unmaintained, and I should update the web page to indicate we are looking for a new owner. I would really like to see someone who is well connected with CIM development help continue it.At the time when it was written we saw a lot of large company interest in CIM and wanted to help out in making writing providers easier for those that were not CIM experts -- writing CIM providers is way too painful, and documentation is scarce. Standardized interfaces, we thought, were definitely a good idea, but the problem was these standards were overcomplicated and that created a high barrier to entry for open-source players (who generally preferred simpler and more transparent technology). Unfortunately, we were unable to drum up community interest among pegasus-list and open source CIM project leaders. As we generally prefer secure XMLRPC ourselves (and are also looking forward towards message bus systems like QPid -- http://cwiki.apache.org/qpid/), there wasn't a lot of sense in continuing to invest in it without community interest from a few CIM experts that could help us out. I should probably update the Cimbiote page to better address it's current status. As I recall, the method support did work fine ... though I forget how to use wbemcli myself. There were some strange issues with it and the way it parsed arguments. Most likely wbemcli is not reading the argument list correctly, and we did encounter a few bugs where calling some CIM functions though wbemcli didn't appear to work (using other providers too, not just with Cimbiote).Maybe I can help you out though ... we used some of the sblim providers for reference when working on Cimbiote, and http://sblim.wiki.sourceforge.net/ might have a service provider. I believe it did, though I do not remember exactly what it supported. Hope that helps out some. If you have any interest in contributing to the project, you are definitely welcome to.Thanks, --Michael
I just remembered that we were using raw WBEM XML with "wbemexec" in the few instances that wbemcli wasn't working for us. Unfortunately I don't have those xml test files lying around anymore. If you want to get involved with something a bit newer, you might want to look at QPid/AMQP and developing your own way of sending commands to and from your nodes rather than CIM. Message buses and CIM are of course totally different, but I think there is a lower barrier to entry and a lot more flexibility there. In particular, I'm not particularly fond of the way CIM handles events (indications)...
