event-filter tapsender filter-name ＜eventType＞ match ＜fieldName＞ ends

Configures a rule to filter out events that are sent from a Network Security appliance to Helix based on a combination of event type, field name, and field value. This command filters out events with a field value that ends with the specified value.

For more information on configuring event filter rules, see the Network Security User Guide.

Note
Helix integration is not supported on the NX x3xx appliances and the NX 10000 appliance.

Important
Make sure the Evidence Collector module is enabled before you add or delete event filter rules. Use the show tapsender status command.

Important
Your event filter configuration changes will not take effect until you apply the changes. The status pending or mark_deleted appears in the show event-filter tapsender configuration <eventType> command output if you did not apply the changes.

Syntax
