David Handermann updated NIFI-16375:
------------------------------------
Status: Patch Available (was: Open)
> Add Lag and Records Metrics to ConsumeKafka
> -------------------------------------------
>
> Key: NIFI-16375
> URL: https://issues.apache.org/jira/browse/NIFI-16375
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: David Handermann
> Assignee: David Handermann
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The {{ConsumeKafka}} Processor should be updated to record the following lag
> and record metrics for each invocation, supporting topic and partition-level
> tracking using the recently-attributes Map of attributes for Counters and
> Gauges.
> * kafka.bytes.consumed
> ** Type: Counter
> * kafka.records.consumed
> ** Type: Counter
> * kafka.records.consumer.lag
> ** Type: Gauge
> * kafka.records.parsed.errors
> ** Type: Counter
> Although the Kafka MetricsReporter provides some capabilities, it does not
> support all of these types of instrumentation details, so implementing the
> Counters and Gauges using ProcessSession methods appears to be the best
> approach.
