# Python WMI

Windows Management Interface connector using asyncio for the Python language.

**Supports:**
- [x] NTLM Authentication
- [x] WMI Query (IWbemServices_ExecQuery)
- [x] Parsing of basic WMI Objects (int/float/str/datetime/array/references)
- [x] Optimized queries using the SmartEnum implementation

**Todo:**
- [ ] Kerberos Authentication
- [ ] Async WMI Query (IWbemServices_ExecQueryAsync)
- [ ] Other DCOM/RPC/WMI calls?
- [ ] Support for WMI Methods?
- [ ] Improve documentation

## Usage

The example below covers most of what is suppored by this library:

```python

import asyncio
import logging
import time
from aiowmi.connection import Connection
from aiowmi.query import Query


async def main():

    host = '10.0.0.1'  # ip address or hostname or fqdn
    username = 'username'
    password = 'password'
    domain = ''  # optional domain name

    # Query has a default namespace 'root/cimv2'
    queries = (
        Query('SELECT * FROM Win32_OperatingSystem', namespace='root/cimv2'),
        Query('SELECT * FROM Win32_NetworkAdapter'),
        Query('SELECT * FROM Win32_LoggedOnUser'),
        Query('SELECT * FROM Win32_PnpEntity'),
        Query('SELECT Caption, Description, InstallDate, InstallDate2, '
              'InstallLocation, InstallSource, InstallState, Language, '
              'LocalPackage, Name, PackageCache, PackageCode, PackageName, '
              'ProductID, RegCompany, RegOwner, SKUNumber, Transforms, '
              'URLInfoAbout, URLUpdateInfo, Vendor, Version '
              'FROM Win32_Product'),
        Query('SELECT Name, DiskReadsPersec, DiskWritesPersec '
              'FROM Win32_PerfFormattedData_PerfDisk_LogicalDisk'),
    )

    start = time.time()

    conn = Connection(host, username, password, domain=domain)
    service = None
    await conn.connect()
    try:
        service = await conn.negotiate_ntlm()

        for query in queries:
            print(f"""

                    # ignore_missing:

                    #       will not be part of the result.
