Package: libzookeeper-java Version: 3.8.0-11+deb12u1 Zookeeper comes with a new metrics systems since 3.6.0, enabling users to monitor several aspects of the service. This new metrics system also supports Prometheus monitoring, see https://zookeeper.apache.org/doc/current/zookeeperMonitor.html#Prometheus. Unfortunately, Debian's libzookeeper-java does not seem to build and bundle the necessary class PrometheusMetricsProvider.
The assumption was that it is possible to monitor Zookeeper on Debian using Prometheus. The system used is Debian bookworm with Java 11/17 and latest Zookeeper packages.
