You can add a configuration to mask sensitive information in all logs or logs that match the filter criteria you provide.

Note:
  • A log mask configuration is applied only to the logs that are ingested after you create and activate the configuration.
  • A log mask configuration is applied only to logs in which the FieldName field and the filter criteria have static fields.

Prerequisites

Verify that you are logged in to the vRealize Log Insight web user interface as a Super Admin user, or a user associated with a role that has the relevant permissions. See Create and Modify Roles for more information. The URL format of the web user interface is https://log-insight-host, where log-insight-host is the IP address or host name of the vRealize Log Insight virtual appliance.

  4. In the Field Name drop-down menu, select the field that you want to mask in the logs.
  5. In the Selector text box, enter the regex selector for the field value, which indicates the part of the field that you want to mask.
    You must express this value as a capture group in the regex. Capture groups are identified with enclosed parentheses (). You can have multiple capture groups inside a selector. To mask all the content for a specified field, you can set the selector as (.*).
  6. In the Mask Value text box, enter a value to replace the masked content of the specified fields, the default value for which is an empty string.
  7. Click ""Add Filter to define the logs for which you want to mask information. If you do not add a filter, all the logs are masked. To see the results of your filter, click Run in Explore Logs page.
