Hello ZooKeeper Community, I am writing to follow up on a pull request I created on GitHub a few weeks ago: *https://github.com/apache/zookeeper/pull/2291 <https://github.com/apache/zookeeper/pull/2291>*
This pull request addresses *ZOOKEEPER-4741*, which describes high latency under heavy load when Prometheus metrics are enabled. The patch modernizes the Prometheus monitoring libraries by switching from the deprecated simpleclient to the prometheus-client APIs. We have deployed this patch on our staging ZooKeeper clusters, and it has been running for over a month with no apparent issues and has shown good performance. I believe this change is a significant improvement for anyone using the Prometheus monitoring feature in ZooKeeper and would appreciate it if a committer could take a look. Please let me know if there are any questions or if I need to take any further steps. Thanks, Vasilii
