Zhilong Hong created FLINK-14065: ------------------------------------ Summary: Log metric name when the metric fails on registration/unregistration Key: FLINK-14065 URL: https://issues.apache.org/jira/browse/FLINK-14065 Project: Flink Issue Type: Improvement Components: Runtime / Metrics Affects Versions: 1.9.0 Reporter: Zhilong Hong Fix For: 1.10.0
When MetricGroup registers Metrics in MetricRegistryImpl, sometimes the registration fails due to exceptions. However, currently it only logsĀ {{"Error while registering metric" }}with no more information, which isĀ inconvenient for users to troubleshoot which metric fails and why it fails. Also, the warning log in registration and unregistration are both "{{Error while registering metric}}". This will lead users to confusion (although users can locate the correct place according to the call stack). So I propose to log metric name when the metrics fails on registration/unregistration. -- This message was sent by Atlassian Jira (v8.3.2#803003)
