5. Status
• Active Development
– Two releases this year
• Extensively tested:
– Mock server implementations in continuous
integration
– OpenPegasus WEB server before each release
– A variety of SMI servers as part of SNI SMI
laboratory/Plugfests
Pywbem Overview 5

6. Possible Usage
• Developing WBEM/ SMI based client applications
that communicate with WBEM servers to manage
SMI or other CIM based environments
• Test tool for other client developers because this
tool is widely tested, open source
• Test tool for WBEM Server development and
testing. It is becoming part of OpenPegasus
internal testing.
• Script based apps/tools for WBEM server
interface
