You can add a configuration to drop logs that match the filter criteria you provide.

Dropping logs lets you view only the logs that you require, which is cost-effective, saves storage, and improves performance.
Note:
  • A log filter configuration is applied only to the logs that are ingested after you create and activate the configuration.
  • A log filter configuration is applied only to logs with static fields in the filter criteria.

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.
