This release adds Prometheus Protobuf support.
As always, the jmx_exporter binaries are available on Maven Central:
NOTES
1. Metrics are no longer served on the root (/) path. You will be required to change the scrape URL to /metrics
2. Some JVM metric names have changed to conform with the OpenMetrics specification.
Dashboards will need to be changed if referencing the changed JVM metrics.
https://prometheus.github.io/client_java/migration/simpleclient/#jvm-metrics
3. MBeans that normalize to the same metric name will now contain a label named _objectname that references the MBean that provided the metric.
Example:
# HELP kafka_rest_jersey_metrics_v3_topics_partitions_reassignment_list_request The request count using a cumulative counter kafka.rest:name=null,type=jersey-metrics,attribute=v3.topics.partitions-reassignment.list.request-total

kafka_rest_jersey_metrics_v3_topics_partitions_reassignment_list_request{_objectname="kafka.rest<type=jersey-metrics><>v3.topics-partitions-reassignment.list.request-total"} 0.0
