--------------------------------------------
+1, [~liwang]. Easier quota monitoring would be very useful!
> Expose Quota Metrics to Prometheus
> ----------------------------------

> Key: ZOOKEEPER-4211
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4211
> Project: ZooKeeper
> Issue Type: New Feature
> Components: metric system
> Reporter: Li Wang
> Priority: Major
>
> In 3.7, Quota limit can be enforced and the quota related stats are captured
> in the StatsTrack. From the "listquota" CLI command, we can the quota limit
> and usage info.
> As an addition to that, we would like to collect the quota metrics and expose
> them to the Prometheus for the following:
> 1. Monitoring per namespace (Chroot) quota usage via the Grafana dashboard
> 2. Creating alert based on the quota levels (e.g. 90% used)
