David Mao created KAFKA-10695: --------------------------------- Summary: Improve interface for sensor expiration Key: KAFKA-10695 URL: https://issues.apache.org/jira/browse/KAFKA-10695 Project: Kafka Issue Type: Improvement Components: metrics Reporter: David Mao
To check whether a sensor has expired, a user should be able to check the return value of {{Sensor.hasExpired()}}.{{ }}However, recording to an expired sensor isn't prohibited, and if a user does record to an expired sensor, we can lose the information that the sensor was expired and removed from metrics. The way we work around this currently, is that all expiring sensors are retrieved from {{Metrics}} each time. A potential improvement would be to add some internal state on whether a sensor has been expired (removed from {{Metrics)}}, and hasExpired should then return that internal state. To do this, we would need to add a new method in Sensor that expresses the intent of expiring a sensor. -- This message was sent by Atlassian Jira (v8.3.4#803005)
