MS SQL SMS Activity Monitor

MS SQL SMS – Microsoft SQL Server management Studio
U njemu je jako zgodan “Acitivity Monitor” koji daje pregled toga ko šta radi nad odabranom bazom.
Napomena : ako Activity Monitor neće da radi kako treba moguće je da se verzije MS SQL SMS-a i same SQL baze ne slažu.
Otvaranje Activity Monitor-a :
1. Kroz ikonicu :
2. Desni klik na ime SQL servera za koji ste zakačeni :
Ali treba znati šta koja kolona znači, i šta znači ono što piše u njoj.
