Description

This dashboard monitors a Postfix mail system, focusing on message flow, delivery latency, and connection integrity. It surfaces operational health indicators such as postfix_cleanup_messages_processed_total and postfix_qmgr_messages_inserted_size_bytes_sum to track processing throughput and message size, while also highlighting latency via postfix_lmtp_delivery_delay_seconds_sum/_count and error/efficiency signals like postfix_cleanup_messages_rejected_total and TLS/SASL/authentication events for security posture.
