Li Wang commented on ZOOKEEPER-4287:
------------------------------------
Please note Prometheus switched to OpenMetrics data model in 0.10.0 release,
which introduces the following changes
1. all Counter samples now have a _total suffix
2. Counter, Summary, and Histogram metrics now expose a _created sample with
when their child was created
More details can be found in the Prometheus change logs
https://github.com/prometheus/client_java/releases
This means that the downstream processing dashboard/alerts may need to make the
change accordingly when upgrading ZK version.
> Upgrade prometheus client library version to 0.10.0
