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.
You can click Reset to restore the default delimiters.
