Statistics Monitoring provides various statistics provided by JEUS through WebAdmin.
A user can select statistics values to create a group. The user can set the group name and description and save it into a file. The group, which consists of selected statistics values, is called a Statistic Preset (hereafter Preset). This section describes how to manage the Statistic Preset.
Note
The Preset configuration is stored in the JEUS_HOME/domains/DOMAIN_NAME/config/monitoring.xml file. If the file is modified, it might generate an error, so be careful not to modify the file.
If the function does not work properly because the file has been modified or damaged, delete the monitoring.xml file. But in such case, the preconfigured presets are also deleted.
Select [Monitoring] > [Statistic] on the left of the WebAdmin screen to go to the Statistic screen.
In the [Statistic] tab, the list of Presets that are currently set are displayed. In this tab, a preset can be added, modified, or deleted, and a preset chart can be viewed. In the [Set] tab, the chart settings such as refresh cycle can be modified.
Adding/Modifying a Preset
To go to the Addition/Modification screen of a preset, click the [Add] button on the Statistic screen or click a preset from the Preset list. Configure items for a Preset and click [OK] to save the Preset configuration and go to the Statistic Screen.
The following describes each field.
| Field | Description |
|---|---|
| Id | Preset identifier that is created automatically. |
| Name | Name that describes the Preset. |
| Description | Detailed description of the Preset. |
| Stats | List of statistics items of the Preset. An item can be deselected by unchecking its check box. |
| Monitoring Items | Tree of statistics items that the Preset can contain. To expand or collapse the tree, click the triangular icon next to each field icon. Name, unit, and description of statistics items are displayed for selection. If an item is clicked, it will be added to the Stats list. |
Deleting a Preset
If the [Delete] button of the Preset to delete is clicked in the Statistic screen, a confirmation message box appears. Click [OK] in the window to delete the Preset.
Select the [Set] tab in the Statistic screen to configure the refresh interval for and the maximum number of items to be displayed on the chart.
If a Preset is selected, WebAdmin displays the statistics of the Preset in a graph. The current state and trend of the statistics can be easily discerned in the chart.
If [chart] is selected from the Preset list in the Statistic screen, the page navigates to the Chart screen.
The Chart screen consists of the following areas.
-
