-------------------------------------
Summary: Log IP addresses from HTTP requests
Key: MESOS-2519
URL: https://issues.apache.org/jira/browse/MESOS-2519
Project: Mesos
Issue Type: Improvement
Reporter: David Robinson
Priority: Minor
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).
