Python client tools to work with WBEM Servers using the PyWBEM API.

Project description

Pywbemtools is a collection of command line tools that communicate with WBEM servers. The tools are written in pure Python and support Python 2 and Python 3.

At this point, pywbemtools includes a single command line tool named pywbemcli that uses the pywbem package on Pypi to issue operations to a WBEM server using the CIM/WBEM standards defined by the DMTF to perform system management tasks.

CIM/WBEM standards are used for a wide variety of systems management tasks in the industry including DMTF management standards and the SNIA Storage Management Initiative Specification (SMI-S).

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.



  1. Python 2.7, 3.4 and higher
  2. Operating Systems: Linux, OS-X, native Windows, UNIX-like environments on Windows (e.g. Cygwin)
  3. On Python 2, the following OS-level packages are needed:
    • On native Windows:
      • choco - Chocolatey package manager. The pywbemtools package installation uses Chocolatey to install OS-level software. See for the installation instructions for Chocolatey.
      • wget - Download tool. Can be installed with: choco install wget.
    • On Linux, OS-X, UNIX-like environments on Windows (e.g. Cygwin):
      • wget - Download tool. Can be installed using the OS-level package manager for the platform.


  • On Python 2, install OS-level packages needed by the pywbem package:

    • On native Windows:

      > wget -q
      > pywbem_os_setup.bat
    • On Linux, OS-X, UNIX-like environments on Windows (e.g. Cygwin):

      $ wget -q
      $ chmod 755
      $ ./

      The script uses sudo internally, so your userid needs to have sudo permission.

  • Install the pywbemtools Python package:

    $ pip install pywbemtools

For more details, including how to install the needed OS-level packages manually, see Installation.
