A system includes a pre-trigger buffer and a post-trigger buffer for recording entries related to specific network element. Buffer management monitoring circuitry captures entries leading up to a trigger criterion being met in the pre-trigger buffer and entries following the trigger criterion being met in the post-trigger buffer. The trigger criterion may include network element status, such as a threshold queue level; or an event, such as a dropped packet. The pre-trigger buffer may include a circular buffer in which older entries are overwritten by newer entries. Once the trigger condition is met, the pre-trigger buffer contents are held while the post-trigger buffer fills. Once the post-trigger buffer fills, the contents of the buffers may be read.
