[jira] [Created] (KAFKA-8844) Add max lso lag metric

Jason Gustafson created KAFKA-8844:
--------------------------------------

             Summary: Add max lso lag metric
                 Key: KAFKA-8844
                 URL: https://issues.apache.org/jira/browse/KAFKA-8844
             Project: Kafka
          Issue Type: Improvement
            Reporter: Jason Gustafson


We have a per-partition metric to monitor the LSO lag. This allows us to track the difference between the high watermark and the LSO, which is useful to detect transactions which are stalled. It would be helpful to have a gauge to monitor the maximum lag across all partitions so that users don't need to collect per-partition metrics.
