Prerequisites for adding Data Collectors (Microsoft Windows server)
64-bit OS. See the Certified Configurations Guide for supported operating systems.
When the IT Analytics system collects data from any vendor subsystem, the collection process expects name/value pairs to be in US English, and requires the installation to be done by an Administrator with a US English locale. The server's language version can be non-US English.
Supports Amazon Corretto 17. Amazon Corretto is a no-cost, multi-platform, production-ready distribution of the Open Java Development Kit (OpenJDK).
For performance reasons, do not install Data Collectors on the same server as the IT Analytics Portal. However, if you must have both on the same server, verify that the Portal and Data Collector software do not reside in the same directory.
Install only one Data Collector on a server (or OS instance).
The collector must have WMI network access to the Windows servers. User credentials must allow access to the root\cimv2, root\Microsoft\Windows\Storage, root\Microsoft\Windows\SMB and root\Microsoft\Windows\NFS WMI namespaces.
The Data Collector Service that is initially installed uses the Local System as the Login account. Sometimes this account does not have permissions to run remote WMI commands. Change the Service configuration to use a Login account that has Local Administrative privileges.
The collector uses a PowerShell script that uses WMI to communicate with the Windows Server, and makes a number of read-only calls to gather the information. PowerShell script execution must be enabled on the system running this script. The PowerShell version on the system must be 5.0 or above.
A full collection path to Windows server attached SAN or NAS storage requires that Host Resource collection be run first against the Windows servers.
WMI uses DCOM for networking. DCOM dynamically allocates port numbers for clients. DCOM's service runs on port 135 (a static port) and any client communicating with a host connects on this port. The DCOM service allocates the specific port for the WMI service.
To set up a fixed port for WMI, see http://msdn.microsoft.com/en-us/library/bb219447%28VS.85%29.aspx.
