Live Session Capture

On connect, a temporary Extended Events session captures every completed batch and stored procedure call, tagged with login, client host and application name.

🧭

Grouped by Who's Asking

Executions are grouped by login, host and application together, so you know exactly which account, machine and app produced a given piece of activity.

📊

Top Queries & Preview

Each group shows its top 5 queries by execution count. Preview opens the full text with line numbers for anything too long to read in the grid.

🔍

Filter Instantly

Narrow the list live as you type, matching against login, client host or application name.

📄

One-Click HTML Report

Create Report produces a self-contained HTML report of everything captured so far, ready to save or print to PDF.

🔒

Read-Only, Self-Cleaning

SqlPulse only reads. The Extended Events session it creates is dropped on disconnect, and everything captured lives in memory only.
