----------------------------------
Assignee: Mingliang Liu
> Improve Elasticsearch 8 connector observability
> -----------------------------------------------
>
> Key: FLINK-35504
> URL: https://issues.apache.org/jira/browse/FLINK-35504
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / ElasticSearch
> Affects Versions: elasticsearch-3.1.0
> Reporter: Mingliang Liu
> Assignee: Mingliang Liu
> Priority: Major
> Labels: pull-request-available
>
> Currently all logs are in DEBUG level. Some of those messages are very
> helpful to get the progress and errors, which can be changed to INFO or WARN
> level. We can also include error details into DEBUG level messages so it's
> easier to debug with more context.
> Meanwhile, we can add a new metric to track
> {{{}numRecordsSendPartialFailureCounter{}}}, which is number of records that
> were returned by Elasticsearch as failed and were retried. FWIW, the base
> class tracks following metrics already so we don't need to implement them:
> {{CurrentSendTime}} Gauge, {{NumBytesOut}} and {{NumRecordsOut}} Counters.
