2. Pywbemcli command

Pywbemcli provides access to WBEM servers from the command line. It provides functionality to:

• Explore the CIM data of WBEM servers. It can manage/inspect the CIM model components including CIM classes, CIM instances, and CIM qualifiers and execute CIM methods and queries on the WBEM server.

• Execute specific CIM-XML operations on the WBEM server as defined in DMTF standard DSP0200 (CIM Operations over HTTP).

• Inspect and manage WBEM server functionality including:

  • CIM namespaces

  • Advertised WBEM management profiles

  • WBEM server brand and version information

• Capture detailed information on CIM-XML interactions with the WBEM server including time statistics and details of data flow.

• Maintain a file with persisted WBEM connection definitions so that pywbemcli can access multiple WBEM servers by name.

• Provide both a command line mode and an interactive mode where multiple pywbemcli commands can be executed within the context of a WBEM server.

• Use an integrated mock WBEM server to try out commands. The mock server can be loaded with CIM objects defined in MOF files or via Python scripts.
