Hi, Sematext's monitoring agent with a ZooKeeper integration is open-source: https://github.com/sematext/sematext-agent-java
The ZK integration is at https://github.com/sematext/sematext-agent-integrations/tree/master/zookeeper (Solr and SolrCloud integrations are in the same repo) If you can't use Sematext Cloud <https://sematext.com/cloud> for monitoring, you can use the above open-source agent and ship ZooKeeper/Solr/SolrCloud metrics to InfluxDB (open-source) and view it with something like Grafana (also open-source).
