Metrics:

Consumed/Produced lag:

sum(kafka_consumer_consumer_fetch_manager_metrics_records_consumed_total{job="mirror-maker", topic="t1"}) - sum(kafka_producer_producer_metrics_record_send_total{job="mirror-maker"})

Rate consumed/produced:

#Consumed
rate(kafka_consumer_consumer_fetch_manager_metrics_records_consumed_total{job="mirror-maker", topic="t1"}[$__interval])
#Produced
rate(kafka_producer_producer_metrics_record_send_total{job="mirror-maker"}[$__interval])
