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.

Quickstart

All commands within pywbemcli show help with the -help or -h options:

$ pywbemcli --help
. . .
$ pywbemcli connection --help
. . .
$ pywbemcli connection save --help
. . .

The following examples build on each other and show a typical sequence of exploration of a WBEM server. For simplicity, they all operate against the default namespace of the server, and use a persistent connection definition for the WBEM server:

Add a persistent connection definition named conn1 for the WBEM server to be used, so that the subsequent commands can refer to it:
```
$ pywbemcli -s https://localhost --no-verify -u user -p password connection save conn1
```
pywbemcli also supports mocked WBEM servers in memory, that are preloaded with CIM objects defined in MOF files. Add a persistent connection definition named assoc1 to a mock server using one of the MOF files provided in the repo:
```
$ pywbemcli -m tests/unit/simple_assoc_mock_model.mof connection save assoc1
```

List the persistent WBEM server connection definitions:

$ pywbemcli connection list
WBEM server connections(brief): (#: default, *: current)
name    server             mock-server
------  -----------------  --------------------------------------
assoc1                     tests/unit/simple_assoc_mock_model.mof
conn1   https://localhost

List the persistent WBEM server connection definitions with full information:

$ pywbemcli connection list --full
WBEM server connections(full): (#: default, *: current)
name    server             namespace    user      timeout  use_pull    verify    certfile    keyfile    mock-server
------  -----------------  -----------  ------  ---------  ----------  --------  ----------  ---------  --------------------------------------
assoc1                     root/cimv2                  30              True                             tests/unit/simple_assoc_mock_model.mof
conn1   https://localhost  root/cimv2   user           30  True        False

Show the class tree, using the previously added WBEM server connection definition assoc1 (specified with the -n option):

$ pywbemcli -n assoc1 class tree
root
 +-- TST_FamilyCollection
 +-- TST_Lineage
 +-- TST_MemberOfFamilyCollection
 +-- TST_Person
     +-- TST_Personsub

Retrieve a single class from that class tree:

$ pywbemcli -n assoc1 class get TST_Person
class TST_Person {

      [Key ( true ),
       Description ( "This is key prop" )]
   string name;

   string extraProperty = "defaultvalue";

};

Enumerate the instances of that class, returning only their instance names by use of the --no option:

$ pywbemcli -n assoc1 instance enumerate TST_Person --no
root/cimv2:TST_Person.name="Gabi"
root/cimv2:TST_Person.name="Mike"
root/cimv2:TST_Person.name="Saara"
root/cimv2:TST_Person.name="Sofi"
root/cimv2:TST_PersonSub.name="Gabisub"
root/cimv2:TST_PersonSub.name="Mikesub"
root/cimv2:TST_PersonSub.name="Saarasub"
root/cimv2:TST_PersonSub.name="Sofisub"

Retrieve a single instance using one of these instance names:

$ pywbemcli -n assoc1 instance get 'root/cimv2:TST_Person.name="Sofi"'
instance of TST_Person {
   name = "Sofi";
};

The instance to be retrieved can also be selected interactively by use of the wildcard instance key ("CLASSNAME.?"):

$ pywbemcli -n assoc1 instance get TST_Person.?
Pick Instance name to process
0: root/cimv2:TST_Person.name="Saara"
1: root/cimv2:TST_Person.name="Mike"
2: root/cimv2:TST_Person.name="Sofi"
3: root/cimv2:TST_Person.name="Gabi"
4: root/cimv2:TST_PersonSub.name="Gabisub"
5: root/cimv2:TST_PersonSub.name="Sofisub"
6: root/cimv2:TST_PersonSub.name="Mikesub"
7: root/cimv2:TST_PersonSub.name="Saarasub"
Input integer between 0 and 7 or Ctrl-C to exit selection: 3
instance of TST_Person {
   name = "Gabi";
};

There are multiple output formats supported. The enumerated instances can for example be formatted as a table of properties by use of the -o table general option (these instances have only one property 'name'):

$ pywbemcli -n assoc1 -o table instance enumerate TST_Person
Instances: TST_Person
+------------+
| name       |
|------------|
| "Gabi"     |
| "Mike"     |
| "Saara"    |
| "Sofi"     |
| "Gabisub"  |
| "Mikesub"  |
| "Saarasub" |
| "Sofisub"  |
+------------+

Traverse all associations starting from a specific instance that is selected interactively:

$ pywbemcli -n assoc1 -o table instance associators TST_Person.?
Pick Instance name to process
0: root/cimv2:TST_Person.name="Saara"
1: root/cimv2:TST_Person.name="Mike"
2: root/cimv2:TST_Person.name="Sofi"
3: root/cimv2:TST_Person.name="Gabi"
4: root/cimv2:TST_PersonSub.name="Gabisub"
5: root/cimv2:TST_PersonSub.name="Sofisub"
6: root/cimv2:TST_PersonSub.name="Mikesub"
7: root/cimv2:TST_PersonSub.name="Saarasub"
Input integer between 0 and 7 or Ctrl-C to exit selection: 1
Instances: TST_FamilyCollection
+-----------+
| name      |
|-----------|
| "Family2" |
| "Gabi"    |
| "Sofi"    |
+-----------+

Other operations against WBEM servers include getting information on namespaces, the Interop namespace, WBEM server brand information, or the advertised management profiles:

Show the Interop namespace of the server:

$ pywbemcli -n conn1 server interop
Server Interop Namespace:
Namespace Name
----------------
root/PG_InterOp

List the advertised management profiles:

$ pywbemcli -n conn1 server profiles --organization DMTF
Advertised management profiles:
+----------------+----------------------+-----------+
| Organization   | Registered Name      | Version   |
|----------------+----------------------+-----------|
| DMTF           | CPU                  | 1.0.0     |
| DMTF           | Computer System      | 1.0.0     |
| DMTF           | Ethernet Port        | 1.0.0     |
| DMTF           | Fan                  | 1.0.0     |
| DMTF           | Indications          | 1.1.0     |
| DMTF           | Profile Registration | 1.0.0     |
+----------------+----------------------+-----------+

Pywbemcli can also be executed in the interactive (REPL) mode by executing it without entering a command or by using the command repl. In this mode the command line prompt is pywbemcli>, the WBEM server connection is maintained between commands and the general options apply to all commands executed:

$ pywbemcli -n conn1
Enter 'help' for help, <CTRL-D> or ':q' to exit pywbemcli.
pywbemcli> server brand

Server Brand:
WBEM Server Brand
-------------------
OpenPegasus
pywbemcli> server interop

Server Interop Namespace:
Namespace Name
----------------
root/PG_InterOp
pywbemcli> :q
