not sure what your question is? you told logstash to output to ES via https setting "ssl=\>true" . You didn't specify cacerts so it was able to find a valid certification path if I'm not misreading this error message > sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested targe ---
