[KIBANA] Xpack notification

[Alessio_Creo]

Hi there,

I've just set the TLS cipher on my production elasticsearch cluster. I have I wathcer scheduled every morning to report a Kibana dashboard and send a pdf via email. Now after the TLS setting I have this error.

"actions": [
      {
        "id": "send_email",
        "type": "email",
        "status": "failure",
        "error": {
          "root_cause": [
            {
              "type": "s_s_l_handshake_exception",
              "reason": "sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
            }
          ],
          "type": "s_s_l_handshake_exception",
          "reason": "sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target",
          "caused_by": {
            "type": "validator_exception",
            "reason": "PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target",
            "caused_by": {
              "type": "sun_cert_path_builder_exception",
              "reason": "unable to find valid certification path to requested target"
            }
          }
        }
      }
    ]
  }

This is my wathcer config

{
  "trigger": {
    "schedule": {
      "daily": {
        "at": [
          "06:30"
        ]
      }
    }
  },
  "input": {
    "none": {}
  },
  "condition": {
    "always": {}
  },
  "actions": {
    "send_email": {
      "email": {
        "profile": "standard",
        "attachments": {
          "error_report.pdf": {
            "reporting": {
              "url": "https://10.0.5.0:5601/api/reporting/generate/printablePdf?jobParams=[...]",
              "auth": {
                "basic": {
                  "username": "watcher",
                  "password": "elastic"
                }
              }
            }
          }
        },
        "to": [
          "control_room@enterprise.com"
        ],
        "subject": "Report applications errors",
        "body": {
          "html": "<p>Error report attached</p>"
        }
      }
    }
  }
}

This is my elasticsearch.yml.

xpack.security.enabled: true

xpack.security.transport.ssl.enabled: true

xpack.security.transport.ssl.verification_mode: certificate

xpack.security.transport.ssl.keystore.path: /Elastic/elasticsearch-6.7.1/config/certs/my_certs.pfx

xpack.security.transport.ssl.truststore.path: /Elastic/elasticsearch-6.7.1/config/certs/cacerts

xpack.security.transport.ssl.client_authentication: none

xpack.security.http.ssl.enabled: true

xpack.security.http.ssl.client_authentication: optional

xpack.security.http.ssl.verification_mode: certificate

xpack.security.http.ssl.keystore.path: /Elastic/elasticsearch-6.7.1/config/certs/my_certs.pfx

xpack.security.http.ssl.truststore.path: /Elastic/elasticsearch-6.7.1/config/certs/cacerts

All the comunication via https work fine, but this one doesn't. Anyone can help me?

Hi there!

It looks like the cert you're using on the Kibana instance is not trusted by your JVM configuration in Elasticsearch. It's possible that the certificate was signed by a CA that is not in your keystore on the JVM. Here's a good answer from StackOverflow on how to add a certificate to your keystore. You'll need to make sure that this cert exists on each Elasticsearch node in your cluster.

Thanks for the answer. In the truststore listed in my elasticsearch.yml the certificate is trusted, I'll try to add it into the java "cacerts" file e see if it works. Thank you again.

I've installed the certiicate in the java cacerts but nothing changed. The same error. Is there any other config I can try to see?

Thank you.
