Configuring Indexes

An index in security analysis is a storage structure used to sort one or more columns in log data. Different index configurations generate different query and analysis results. Configure indexes based on your requirements.

If you want to use the analysis function, field indexes are mandatory. After configuring a field index, you can specify field keys and field values to narrow down the query scope. For example, the query statement level:error is to query logs whose level field contains the value error.

Limitations and Constraints

Custom index can be configured only for new custom pipelines. For details, see Creating a Pipeline.
Field indexes cannot be deleted.

Configuring Field Indexes

Log in to the management console.
Click in the upper left corner of the management console and select a region or project.

Figure 1 Workspace management page
In the navigation pane on the left, choose Threat Operations > Security Analysis. The security analysis page is displayed.

Figure 2 Accessing the Security Analysis tab page
In the data space navigation tree on the left, click a data space name to show the pipeline list. Click a pipeline name. On the displayed page, you can search the pipeline data.

Figure 3 Pipeline data page
On the pipeline page, click Index Settings in the upper right corner.

On the Index Settings page, configure index parameters.

Enable the index status.
The index status is enabled by default. When the index status is disabled, collected logs cannot be queried using indexes.

Configure index parameters. For details about the parameters, see Table 1.

**Table 1** Parameters for index settings
Parameter	Description
Field	Log field (key)
Type	Data type of the log field value. The options are text, keyword, long, integer, double, float, date, and json.
Includes Chinese	Indicates whether to distinguish between Chinese and English during query. This parameter needs to be specified when Type is set to text. After the function is enabled, if the log contains Chinese characters, the Chinese content is split based on the Chinese grammar and the English content is split based on delimiters. After this function is disabled, all content is split based on delimiters. Example: The log content is user:WAF log user Zhang San. After Includes Chinese is disabled, the log is split based on the colon (:). So it is split into user and WAF log user Zhang San. You can search for the log by user or WAF log user Mr. Zhang. After Includes Chinese is enabled, the LTS background analyzer splits the log into user, WAF, log, user, and Zhang San. You can find logs by searching for log or Mr. Zhang.
