• PSSDIAG/DiagManager — legacy SQLDiag-based collection tool

Automated Installation of Prerequisites

You can use the following PowerShell script to install all prerequisites automatically:

1. Copy the file (or its contents to a new file with a .ps1 extension) onto the target system

2. Run using the following command:

   powershell -File SetupSQLNexusPrereq.ps1

Installation Steps

1. Download the latest binary files from Releases
2. Unzip the file to a local directory
3. Run sqlnexus.exe to start SQL Nexus

⚠️ Important: Do not point SQL Nexus at a production SQL Server instance. Use a dedicated non-production instance for importing and analyzing data.
