[syslog-ng] Syslog-ng OSE Question.

Hi, Is it possible to have syslog-ng client to invoke an external (to it) software to acknowledge when each individual log statement is sent to the server? Background: logs should not be lost. The system needs to store logs internally until they are transmitted to the server (use of TCP transport provides a level of reliable delivery). After each log statement is transmitted by syslog-ng client, it needs to be removed from internal store to preserve allocated space. Thank you for your help! --Vlad
