We're trying to learn how to setup TLS on elastic. We have a 1 node stack with version 6.6.1, working on getting logstash setup. All output is in pipelines. Getting this error at startup:
[WARN ][logstash.outputs.elasticsearch] ** WARNING ** Detected UNSAFE options in elasticsearch output configuration!
** WARNING ** You have enabled encryption but DISABLED certificate verification.
** WARNING ** To make sure your data is secure change :ssl_certificate_verification to true
That seems to be the default and I don't have ssl_certificate_verification anywhere in the config (verified by grep -ri) . I think it may be from something in the xpack.monitoring config, but I have nothing there for verification either.
