I am setting up my cluster with encryption and need to disable certificate verification. All settings work correctly except for xpack monitoring of logstash. There is no setting to disable certification verification for xpack monitoring of logstash.
Neither pages about Logstash and SSL mention any way to do this:
https://www.elastic.co/guide/en/x-pack/current/monitoring-logstash.html
https://www.elastic.co/guide/en/logstash/current/settings-xpack.html
The error that I get is:
