The table can contain the following columns:
Column  | Description  | 
Time  | The date and time of sending the command from the server.  |

Command name  | The name specified when creating the command.  | 
Command type  | The type selected when creating the command.  | 
Parameters  | The command parameters specified when creating or sending the command (if applicable). You can filter the commands by these parameters.  | 
Execution time  | The date and time of executing the command. If the command couldn't be executed due to the billing plan limitations, a dash is displayed. This may happen, for example, if the SMS channel is used for sending the command when the limit of available SMS messages has already been reached.  |
