Default Level
1: Monitor level
Parameters
entry-number: Number of entries to be displayed, in the range of 1 to 60.
offset: Offset between the serial number of the first CPU usage statistics record to be displayed and that of the last CPU usage record to be displayed. It is in the range of 0 to 59. For example, the idx of the latest statistics record is 12, if the offset is set to 3, the system will display the statistics records from the one with the idx of 9. idx represents the serial number of the period for the statistics, and its value ranges from 0 to 60 cyclically. The system makes CPU usage statistics periodically; after each period, the system records the average CPU usage during this period, and the idx value is added by 1 automatically.
verbose: Specifies to display detailed information of CPU usage statistics. If this keyword is not provided, the system displays the brief information of the CPU usage statistics; if this keyword is provided, the system displays the average CPU usage statistics for each task in the specified period.
from-device: Displays external storage media such as flash and hard disk. The device currently does not support the from-device keyword.
Description
Use the display cpu-usage command to display the CPU usage statistics.
The system takes statistics of CPU usage at intervals (usually every 60 seconds) and saves the statistical results in the history record area. display cpu-usage entry-number indicates the system displays entry-number records from the newest (last) record. display cpu-usage entry-number offset indicates the system displays number records from the last but offset record.
Equivalent to the display cpu-usage 1 0 verbose command, the display cpu-usage command displays detailed information of the last CPU usage statistics record.
Examples
# Display information of the current CPU usage statistics.

Default Level
3: Manage level
Parameters
at time1 [ date ]: Specifies the execution time of a specified command.
l time1: Execution time of the command, in the format of hh:mm (hour/minute). The hh value ranges from 0 to 23, and the mm value ranges from 0 to 59. The value of hh:mm cannot exceed 23:59.
l date: Execution date of the command, in the format of MM/DD/YYYY (month/day/year) or YYYY/MM/DD (year/month/day). The YYYY value ranges from 2000 to 2035, the MM value ranges from 1 to 12, and the DD value range depends on a specific month.
delay time2: Specifies the execution waiting time of a specified command. time2 represents the waiting time, which can be in the following format:
l hh:mm (hour/minute): The hh value ranges from 0 to 720, and the mm value ranges from 0 to 59. The value of hh:mm cannot exceed 720:00.
l mm (minute): It ranges from 0 to 432000, with 0 indicating that a command is executed immediately without any delay.
view view: Specifies the view in which a command is executed. view represents the view name, and it takes the following values at present:
l shell, represents user view.
l system, represents system view.
command: The command string to be automatically executed at the scheduled time.
Description
Use the schedule job command to automatically execute a specified command at the scheduled time.
Use the undo schedule job command to remove the configuration.
Note the following:
l If you provide both the time1 and date arguments, the execution time must be a future time.
l If you only provide the time1 argument, when time1 is earlier than the current system time, the specified command is executed at time1 of the next day; when time1 is later than the current system time, the specified command is executed at time1 of the current day.
l No matter whether you use the at or delay keyword, the difference between the execution time of a command and the current system time cannot exceed 720 hours (namely, 30 days).
l At present, you can specify only user view and system view. To automatically execute the specified commands in other views or automatically execute multiple commands at a time, you can configure the system to automatically execute a batch file at a specified time (note that you must provide a complete file path for the system to execute the batch file.).
l The system does not check the view and command arguments. Therefore, ensure the correctness of the command argument (including the correct format of command and the correct relationship between the command and view arguments.).
l After the specified automatic execution time is reached, the system executes the specified commands without displaying any information except system information such as log, trap and debug.
l When the system is executing the specified command, you do not need to input any information. If there is information for you to confirm, the system automatically inputs Y or Yes; if certain characters need to be input, the system automatically inputs a default character string, and inputs an empty character string when there is no default character string.
l For the commands used to switch user interfaces, such as telnet, ftp, and ssh2, the commands used to switch views, such as system-view, quit and interface ethernet, and the commands used to modify status of the user that is executing commands, such as super, the operation interface, command view and status of the current user are not changed after the automatic execution function is performed.
l If you modify the system time after the automatic execution function is configured, the scheduled automatic execution configuration turns invalid automatically.
l Only the latest configuration takes effect if you execute the schedule job command repeatedly.
Examples
# Configure that the device will execute the batch file 1.bat in system view in 60 minutes (supposing that the current time is 11:43).
<Sysname> schedule job delay 60 view system execute 1.bat
Info: Command execute 1.bat in system view will be executed at 12:43 10/31/2007 (in 1 hours and 0 minutes).
# Configure that the device will execute the batch file 1.bat in system view at 12:00 in the current day (supposing that the current time is 11:43).

l When the specified reboot time is earlier than the current time, the device will be rebooted at the reboot time the next day.
l If you are performing file operations when the device is to be rebooted, the system does not execute the command for the sake of security.
Note that:
l The precision of the device timer is 1 minute. One minute before the reboot time, the device will prompt “REBOOT IN ONE MINUTE” and will be rebooted in one minute.
l The difference between the reboot date and the current date cannot exceed 30 x 24 hours (namely, 30 days).
l After you execute the above command, the device will prompt you to confirm the configuration. You must enter Y or y to make the configuration take effect. The original configuration will be overwritten at the same time.
l If a date (month/day/year or year/month/day) later than the current date is specified for the schedule reboot at command, the device will be rebooted at the reboot time.
l If you use the clock command after the schedule reboot at command to adjust the system time, the reboot time set by the schedule reboot at command will become invalid.
