| User | The name of the user who runs the operation. |
| Host | The hostname of the client which runs the operation. |
| Db | The name of the database where the operation is executed. |
| Command | The type of the command. |
| ConnectionStartTime | Time when the connection starts. |
| Time | The time (in second) since the operation has entered the current state. |
| State | The state of the operation. |
