Reload System Group, Agent tree	If the system group or Agent tree is displayed, the Monitor tree can be reloaded without changing the tree hierarchy by selecting the target node.

7.3.2 Basic operation

When a monitor to be displayed is selected in the Monitor tree on the left, the monitored content will be displayed on the right.

While the content is being generated, the message "Now generating contents" will appear in the status bar.

While this message is displayed, the Update and Auto Update buttons will be disabled.

7.3.2.1 Manual Update and Auto Update

The Monitor can be manually or automatically updated with the most recent information.

The options shown in the following table can be specified when performing the update process.

Option	Description
Reference point	Select the reference point for displaying the Monitor. The following reference points can be selected: As of now, Specified date If As of now is selected, the Monitor will be displayed with the current time as the reference point. If Specified date is selected, any time in the next three days can be selected as the reference point.
Range/Display number	Select the display range as the number of hours leading up to the present time. The following display periods can be selected: 1, 2, 4, 8, 12, 18 and 24 hours The default period is 2 hours. For the number of display items, either "All" or an arbitrary number of items can be specified. For the disk usage rate to prevent the high utilization of the disk etc, the number of data items to display in the report is extracted by a high-ranking number. For the free disk space to prevent full disk usage etc, the number of data items to display in the report is extracted by a low-ranking number. The number of data items to display to be displayed in the report is about up to 20. It becomes difficult to distinguish because the display area and the line in the report increase when the number of data items is any more.
Interval (for Auto Update)	Select the interval to be used in auto updates. The following update intervals can be selected: 1, 3, 5 and 10 minutes The default value is 10 minutes. Note that if the current content of the Monitor view is still being displayed when the next automatic refresh is due, then this next refresh will be skipped, and the content will be updated with the following refresh.

To remove the need to specify the same option many times, once an option is specified, it is inherited by other monitors.

If it is necessary to open multiple Consoles to display different types of monitors at the same time and view them at different automatic update intervals, and if Internet Explorer is the browser being used, the different options can be specified by starting Internet Explorer separately from the Start menu. If a new Console is opened from the Console toolbar, the options of the parent Console that is already open will be inherited.

7.3.2.2 Opening targets in Drill Down view

When the content of a monitor is displayed, a link entitled Open target in Drill Down view will be displayed in the top-right of the content window.

When this link is clicked, a Console will open with the target selected by the monitor selected in Drill Down mode.

This function makes it possible to quickly open a drill down view when a problem is detected by a monitor.

7.3.3 Content-related operation methods

This section explains the operations that can be performed on displayed monitor content.

Table sorting

When the header section of any column in a table displayed in monitor content is selected, the table can be sorted using the selected column as the sort key.

Sorting can be toggled between ascending and descending order.

Numerical sorts operate correctly only when all the values in the specified column are numerical values. Sorting cannot be performed correctly if the column contains non-numerical data such as null values.
Date and time sorts cannot be performed correctly if the number of digits (yyyy/mm/dd hh:mm:ss, etc.) is not uniform throughout the column. Care must be taken when data has been imported from user data.

Data download

The following link is available at the bottom of the Monitor contents:
