# HELP agent_boundary_log_proxy_logs_dropped_total Total number of individual boundary log entries dropped before reaching coderd. Reason: buffer_full = the agent's internal buffer is full; forward_failed = the agent failed to send the batch to coderd; boundary_channel_full = boundary's internal send channel overflowed, meaning boundary is generating logs faster than it can batch and send them; boundary_batch_full = boundary's outgoing batch buffer overflowed after a failed flush, meaning boundary could not write to the agent's socket.
