------------------------------------
I cleaned up the test in [https://github.com/apache/lucene-solr/pull/1786] -
will commit to branch_8x
> Zookeeper status fails on zk 3.6.1 with prometheus enabled
> ----------------------------------------------------------
>
> Key: SOLR-14752
> URL: https://issues.apache.org/jira/browse/SOLR-14752
> Project: Solr
> Issue Type: Bug
> Components: Admin UI
> Affects Versions: 8.6
> Reporter: Philipp Trulson
> Assignee: Jan Høydahl
> Priority: Major
> Time Spent: 50m
> Remaining Estimate: 0h
>
> We specifically waited for SOLR-14463 to be released so it works fine with
> zookeeper 3.6, but unfortunately we still have problems. The reason could to
> be that in
> [ZookeeperStatusHandler.java|https://github.com/apache/lucene-solr/blob/releases/lucene-solr/8.6.0/solr/core/src/java/org/apache/solr/handler/admin/ZookeeperStatusHandler.java#L152]
> it explicitly expects integers to parse. But it seems that if you enable the
> [new prometheus
> metrics|https://zookeeper.apache.org/doc/r3.6.1/zookeeperMonitor.html#Prometheus]
> in zookeeper all the values are posted as floats instead and that makes your
> check fail.
> This is our output of 'echo mntr | nc zookeeper 2181'
