expose zone timers (reload, refresh, expire) via stats channel
A customer has requested:
It would be very helpful for us to have the various zone timers exposed through the statistics channel. The information is currently available through
rndc zonestatus, but it would be far easier for us to monitor the servers if this were accessible through the stats channel.
Our use case would be to monitor for zones approaching expiration. We'd like to use the stats channel to pull the full list of zones with the timers in one operation, and then parse the data.
