Seeing this repeatedly in Elasticsearch logs:
[2018-04-09T11:13:05,858][DEBUG][o.e.x.s.a.a.OptOutQueryCache] [SERVER.FQDN] [.monitoring-logstash-6-2018.04.09] opting out of the query cache. current request doesn't hold indices permissions
Why is this being logged, is it a permission issue and if so, with which account? I believe I am using the elastic user account for connections between applications.
