> Querying /master/state.json is an expensive operation when a cluster is large, and it's possible to DOS the master via frequent and repeated queries (which is a separate problem). Querying the endpoint results in a log entry being written, but the entry lacks useful information, such as an IP address, response code and response size. These details are useful for tracking down who/what is querying the endpoint. Consider adding these details to the log entry, or even writing a separate [access|https://httpd.apache.org/docs/trunk/logs.html#accesslog] [log|https://httpd.apache.org/docs/trunk/logs.html#common]. Also consider writing log entries for _all_ HTTP requests (/metrics/snapshot produces no log entries).
