Configuring Extended Meta Keys

[#1]

Extended meta keys are configured in the index file using the attribute maxValueLength.

For example:

<key description="Querystring" name="query" format="Text" level="IndexKeys" maxValueLength="4096" />

Here we have defined the meta key query to save values up to 4,096 bytes in size. Any values exceeding 4k in length will be truncated to 4k.

Note: A capture restart is required for any changes to maxValueLength take effect.

The maximum value of maxValueLength is 4k (4,096 bytes).

Index Files

When configuring the index-*.xml files, the maxValueLength setting needs to be added to the source devices' language file only (that is, index-decoder.xml and index-logdecoder.xml). It is not required to add the setting to Concentrators, Archivers and so on.

The maxValueLenth setting is also supported in the *-custom.xml files (that is, index-decoder-custom.xml).
