InfluxDB metrics on number of concurrent queries, number of http connections and number of concurrent writes

I am using Grafana to create a dashboard on InfluxDB internal metrics. I am doing http “get” call with query as “show stats” to gather all of the information. I am looking for following metrics and don’t know where to get that. I tried looking into httpd, queryExecutor, runtime, shard, tsm1_cache, tsm1_engine, tsm1_filestore, tsm1_wal, and write.
I see in [coordinator] config section, we have “max-concurrent-queries” whose default is set to 0. Are we exposing number of concurrent queries running at a given time? If yes, where do I find it?
I see in [http] config section, we have config setting for “max-connection-limit” and default is set to 0. Are we exposing number of http connections at a given time? If yes, where do I find it?
Similarly, max-concurrent-write-limit is set to 0 by default. Where do I find number of concurrent write happening at a given time?

I am assuming, in httpd measurement, field req is for number of requests, field queryReq is for number of query requests, and field writeReq is for number of write requests.
