This feature is supported in the Health Log Analytics application, Version 20.0.11 - July 2021, and the Health Log Analytics Viewer application, Version 20.0.4 - July 2021, available from the ServiceNow Store.

手順

1. Open the Log Viewer using one of the following methods:
   • Navigate to Workspaces > Service Operations Workspace and select the Log Viewer icon ().
   • While viewing log entries for an alert on the Surrounding logs tab, select Log Viewer.
2. Select the filter icon () to display the Filters pane.
   The Selected fields list includes the fields that currently display as columns in the Log viewer table. By default, the table includes the following columns: Application service, Component, Host, Level, Message, Raw message, and Time. The Available fields include all remaining fields that the system has extracted from the log.

   In the Service Operations Workspace Log Analytics application, Version 21.2.7 - November 2022 and later, available from the ServiceNow Store, the Log message column is added and the Raw message column no longer displays by default. You can add the Raw message column to the table by selecting it from the Filters pane.

3. Add or remove columns in the Log viewer table.
   • To add a column to the table, select the field of the same name in the Available fields list and then select the add icon ().

     The added field displays as a column in the table. It is now listed in the Selected fields list.

   • To remove a column, select the field of the same name in the Selected fields list and then select the remove icon ().

     The corresponding column is removed from the table. The removed field is added to the Available fields list.

     If you have filtered the data for specific values in a field, that data still displays even when the field is no longer selected. For more information about filtering data, see Filter search results on the Log Viewer in Health Log Analytics.

     注:

     The Time column can't be removed from the table.
4. オプション: Adjust the maximum number of characters per field in the table.
   1. Navigate to Health Log Analytics > Health Log Analytics Administration > System Properties.
   2. Open the sn_occ.log_viewer.max.characters property record.
   3. In the Value field, edit the default value.
   4. Select Update.
