I wrote a Kibana plugin - https://github.com/sivasamyk/logtrail and a few graylog plugins which opened many doors for me. It also helped me land my last job at Sematext. I lost interest in maintaining the plugin after Elastic's open-source license changes.
At Sematext we replaced our HBase based metrics datastore with Clickhouse. We are happy with the performance gain and flexibility. We also added support for Clickhouse monitoring - https://sematext.com/blog/clickhouse-monitoring-sematext/
https://github.com/sivasamyk/logtrail - A Kibana plugin to view and tail logs. Started as project to scratch my own itch and now used by many. Technology : AngularJS and NodeJS. Currently working on a major enhancement for this project :)
I submitted logtrail (https://github.com/sivasamyk/logtrail) 312 days ago (more of a side project of mine) and made it to front page. Got lots of stars :). Helped me boost my confidence and currently has active users and made multiple releases with new features. Happy I did it.
