What is WMI architecture?
WMI is an implementation of the Web-Based Enterprise Management (WBEM) standard. WMI provides a uniform access mechanism to a vast collection of Windows management data and methods. WMI offers access to this information via script, C++ programming interfaces, dot net classes (system.
What are the 3 components in the WMI architecture?
The WMI architecture has three main components: WMI providers (and managed objects) – COM objects that give access to managed objects. A managed object is a computer component such as a process, a hard drive and so on. WMI infrastructure – core OS components that provide consistent access to WMI-managed objects.
What are the components of the WMI infrastructure?
The WMI infrastructure has two components: the WMI Core, and the WMI repository. The WMI repository is organized by WMI namespaces.
What is WMI database?
A Windows Management Instrumentation (WMI) Database is a repository of software drivers, applications and extensions available in the Windows operating system.
Does WMI rely on SNMP?
The Simple Network Management Protocol (SNMP) provider allows client applications to access SNMP information through Windows Management Instrumentation (WMI). The SNMP provider is not installed by default. For more information about installing the provider, see Setting up the WMI SNMP Environment.
Does SolarWinds use WMI?

| Requirement | Systems |
|---|---|
| Distributed Component Object Model (DCOM) File and Print Sharing RPC Service WMI Firewall Exception | Remote systems |
What is difference between WMI and SNMP?
SNMP (Simple Network Management Protocol) is a non-proprietary communication protocol for network devices, whereas WMI (Windows Management Interface) is a Microsoft protocol. There are some things only one of them can do, and some that both can do. It varies a lot.
What is WMI polling?
This polling method can only be used for Windows computers. Windows Management Instrumentation (WMI) is a proprietary technology used to poll performance and management information from Windows-based network devices, applications, and components.
Is WMI TCP or UDP?
WMI is based on the Distributed Component Object Model (DCOM) which, by default, uses a randomly selected TCP port between 49152 and 65535 for communications.
What is the difference between WMI and SNMP?
What port is used by WMI?
What Ports Does WMI Use? WMI uses TCP port 135 and a range of dynamic ports: 49152-65535 (RPC dynamic ports – Windows Vista, 2008 and above), TCP 1024-65535 (RPC dynamic ports – Windows NT4, Windows 2000, Windows 2003), or you can set up WMI to use a custom range of ports.
Does WMI use port 445?
In cases where a range is provided, one of the ports is used after initial negotiation. By default, WMI (DCOM) uses a randomly selected dynamic port range for TCP between 49152 and 65535….WMI.
| Port Number | Port assignment |
|---|---|
| 445 | Microsoft Directory Services SMB |
Should I use SNMP or WMI?
WMI can be easier to set up, but can also consume more resources to do the same thing; if you have many monitors or devices in your task, SNMP is often the better choice. Conversely, SNMP generates less overhead in monitoring, but can be more difficult to configure.
What is DCOM and WMI?
To poll devices using the WMI protocol, you need to properly set up Windows Management Instrumentation (WMI) and Distributed Component Object Model (DCOM) on all Windows servers to be polled. The following steps were tested on Windows Server 2008 R2 SP1 and may differ slightly on Windows Server 2012.
