Overview of Log Viewer

The Log Viewer application allows you to view the historical data related to system activities and events directly without creating and configuring a report from the Reports application.

The information related to all the system activities and events displays in a tabular format.
You can create a subset of this information by applying the necessary configurations such as filters, identifying the columns to display, specifying the number of records to display,
and other settings, such as resizing the column width or re-ordering the columns.

Once configured, this information can be saved as a log view definition that can be used later.
When you access the log view definition at a later date, the latest data, according to the configurations that you have applied to the definition, displays.

When you save the data as a log view definition that has sorting applied, the sort criteria is also saved.
The next time when you load the log view definition, the data with the saved sort criteria displays.

In a distributed system, the data from all the systems displays in the log view grid.

You can view log data using any of the following procedures:

Selecting the Log Viewer root node, a log view folder, or a saved log view definition from the System Browser.
Selecting an object from System Browser: This displays the Activity and Event Log records for the selected object in the Detailed Log tab.
Selecting an object from any application such as Graphics, Trends, Textual Viewer, or Reports:
This displays the latest 100 Activity and Event Log records for the object in the Detailed Log tab.
Selecting an Activity type or Event type record in the log view:
When you select an Activity type record from a log view, the latest 100 Activity and Event Logs for the selected object display in the Detailed Log tab.
However, if an Event type record is selected, the details of the selected event including the different state changes of the event and the user activities performed in context of the event are displayed in the Detailed Log tab.
For example, a single event type can trigger multiple notifications, therefore, the multiple activity logs for the messages gets added in the platform’s activity log.
Selecting an event from Event List: Displays information about the object involved in the event in the Detailed Log tab.

However, if you have selected more than one object, the Detailed Log tab does not display any information.

NOTE:
When you select the Log Viewer root node, a log view folder, or a saved log view definition from System Browser, you may see the following message above the log view table: Configured View Size reached! Refine search via Search Filter. This means that there are more records in the database than can be displayed in the defined view size. In order to view such records you must either specify filters or modify existing filters.
