Configuring Log Content Delimiters¶
You can configure delimiters to split log content into words, so you can search for logs by these words. LTS has preconfigured the following delimiters:
, '";=()[]{}@&<>/:\n\t\r
If the default delimiters cannot meet your needs, you can set custom delimiters.
Precautions¶
Your custom delimiters are applicable only to the log events generated after the delimiters are configured.
The delimiter configured on the Delimiters tab page takes effect for all log streams in the current region. For details about how to configure delimiters for a single log stream, see Setting Indexes.
Procedure¶
Log in to the management console and choose Management & Deployment > Log Tank Service.
Choose Configuration Center in the navigation pane and click the Delimiters tab.
Configure delimiters.
You can configure delimiters in either of the following ways. If you use both ways, the delimiters configured in the two ways will all take effect.
Common Delimiters: Click Edit and enter custom delimiters in the text box.
ASCII Delimiters: Click Edit > Add ASCII Delimiter, and enter ASCII values by referring to ASCII Table.
Preview the parsing result.
Enter log content in the text box and click Preview.
Check whether the parsing result is correct. If it is correct, click Save.
Note
You can click Reset to restore the default delimiters.
