Hi Team,
We are unable to see monitoring data after upgrading to 6.6.1. I just see a bank page when i click on monitoring page.
Here is my kibana.yml content
server.port: 5601
server.host: hostname
server.maxPayloadBytes: 10485760
elasticsearch.hosts: "[https://hostname:9200](https://hostname:9200)"
elasticsearch.requestTimeout: 180000
kibana.index: .kibana
logging.dest: /logs/kibana.log
elasticsearch.username: "------"
elasticsearch.password: "------"
elasticsearch.ssl.verificationMode: none
server.ssl.enabled: true
server.ssl.key: "-.key"
server.ssl.certificate: "-.crt"
server.ssl.keyPassphrase: "------"
xpack.security.enabled: false
xpack.monitoring.enabled: true
kibana.defaultAppId: "discover"
Thanks

Hi @vissu,
Are there any errors in the browser or Kibana server log?

I see this error.
{"type":"log","@timestamp":"2019-03-06T13:52:04Z","tags":["error","elasticsearch","monitoring-ui"],"pid":13798,"message":"Request error, retrying\nPOST [https://hostname:9200/](https://hostname:9200/)_%3A.monitoring-es-2-_%2C\*%3A.monitoring-es-6-_%2C.monitoring-es-2-_%2C.monitoring-es-6-\*/\_search?size=10000&ignore\_unavailable=true&filter\_path=hits.hits.\_index%2Chits.hits.\_source.cluster\_uuid%2Chits.hits.\_source.cluster\_name%2Chits.hits.\_source.version%2Chits.hits.\_source.license.status%2Chits.hits.\_source.license.type%2Chits.hits.\_source.license.issue\_date%2Chits.hits.\_source.license.expiry\_date%2Chits.hits.\_source.license.expiry\_date\_in\_millis%2Chits.hits.\_source.cluster\_stats%2Chits.hits.\_source.cluster\_state%2Chits.hits.\_source.cluster\_settings.cluster.metadata.display\_name =\> socket hang up"}

You might have connectivity issues between your Kibana instance and your ES instance. What does your infrastructure look like? Are the two machines (assuming they are running on separate machine) able to communicate?
