SQL Monitor can monitor sql server processes and jobs, view executing sql query, kill process / job. it uses linq and requires .net 3.5 (client profile). right now it is very primitive, but I will improve it significiantly.

SQL Monitor Features:
1. Supports processes and jobs
2. Keep tracking actual running sql query
3. Automatically load LAN SQL server instances

Requirements:
* NET Framework
* SQL Server
