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 time when the delimiters are configured. Earlier logs are processed based on earlier delimiters.

Procedure

In the navigation pane, choose Configuration Management > Log Configuration, and click the Delimiter Configuration tab.
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.
- Customize delimiters. Specifically, click , enter a delimiter in the text box, and click .
- Use ASCII code. Specifically, click Add Special Delimiters, enter the ASCII value according to ASCII Comparison Table, and click .
Preview the log content.
Enter the log content to be previewed in the text box and click Preview. For example, if the comma (,) and brackets ([]) are used as delimiters, the preview effect is as follows:

Confirm the configuration and click OK.
Click Reset to restore the default configuration. Default delimiters are as follows:
```
, '";=()[]{}@&<>/:\n\t\r
```
