> Ratis events should not be published as metrics

> Key: HDDS-15552
> URL: https://issues.apache.org/jira/browse/HDDS-15552
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Ethan Rose
> Assignee: Wei-Chiu Chuang
> Priority: Major
> Labels: pull-request-available
>
> HDDS-13133 started tracking Ratis events (arbitrary strings) as metrics.
> These then get exposed over JMX and Prometheus. This completely prevents
> Prometheus from scraping these endpoints because it fails when any of the
> messages have invalid characters like " or \n. We can keep the list of events
> in memory and maintain the web UI functionality without exposing it as a
> metric.
> Additionally to verify this change, we should add an acceptance test call to
> {{GET http://<prometheus-host>:9090/api/v1/targets}} and ensure that
> {{health=up}} for each component to prevent future regressions like this.
