[Reproduction Path] What operations were performed when the issue occurred
After using tiup cluster edit-config
, an error occurred when using the reload command: Error: failed to get leader count node175.tidb.fee.net.chinamobile.com: metric tikv_raftstore_region_count{type="leader"} not found
. The TiKV log is as follows:
The log shows that it cannot obtain monitoring information through the domain name. By checking the port, it was found that port 20180 is listening on the IPv4 protocol stack, and it cannot be accessed through the IPv6 address.

However, the TiKV startup script is as follows, and the option
--advertise-status-addr
should listen on the IPv6 protocol stack, but it does not.Please advise.
