Current level of tcp-clients missing from statistics channel
The current level of tcp-clients from rndc status as shown in this screen shot:
Is not included in the json, nor xml output from the statistics channel. Only TCPConnHighWater is included, which reports the max simultaneous TCP connections that existed at some point since BIND was started. The current level is not exposed anywhere in the stats channel that I could find. It is exposed, however, in rndc status as shown above. it seems reasonable that this statistic should be exposed for monitoring in the stats channel.
