Configuring Delimiters¶
AOM enables you to divide the log content into multiple words for search by configuring delimiters. By default, AOM provides the following delimiters:
, '";=()[]{}@&<>/:\n\t\r
If default delimiters cannot meet requirements, customize delimiters according to the following procedure.
Precautions¶
Delimiters are applicable only to the logs generated after the delimiters are configured. Earlier logs are processed based on earlier delimiters.
Procedure¶
Log in to the management console.
Under Application, click Application Operations Management.
In the navigation pane, choose Log Management > Configuration Center.
Configure delimiters.
You can configure delimiters using the following methods: If you use both methods at the same time, the union set will be selected.
Custom delimiters: Click
, enter a delimiter in the text box, and click
