------------------------------------------
Summary: Make open telemetry object instantiation configurable
Key: KAFKA-19727
URL: https://issues.apache.org/jira/browse/KAFKA-19727
Project: Kafka
Issue Type: Bug
Components: config
Affects Versions: 4.0.0, 3.9.0, 3.8.0, 3.7.0
Reporter: Jonathan Lacefield
After the 3.7 release of Kafka, the java client will emit many warning messages
and more objects deployed due to an open telemetry object instantiation
(possibly due to KIP-714). It appears the open telemetry feature was enabled by
default and there's no way for a user to disable it.
Users receive the INFO message defined [here
|https://github.com/apache/kafka/blob/3.7.2/clients/src/main/java/org/apache/kafka/common/telemetry/internals/ClientTelemetryReporter.java#L479]
after activating INFO log level for
"org.apache.kafka.common.telemetry.internals.ClientTelemetryReporter" class.
This log line appears lots of times.
It appears that the occurrence of this info messages shows ClientTelemetry
objects are being created if the feature is not explicitly disabled. Users
would like this feature to be opt-in and not enabled by default as it is.
