This RowStatus object governs the creation, activation, and deletion of a custom pattern-matching rule row in the application-signature table, following the standard SNMP conceptual-row lifecycle. Administrators must ensure the associated etsysAppSignPattern string is actually populated before this can be set to active, since the device will reject activating a rule with an empty match pattern. For example, an admin defining a new pattern to detect traffic to 'mycompany-app.example.com' would first set the pattern string, then set this row status to active to put the rule into effect.
