Hi Team,  
I have installed heartbeat in one of my server and try parsing them to elastic search for some specific urls' all i could see "x509: certificate signed by unknown authority" messages in the kibana. My heartbeat.yml looks like below.

```
############################# Heartbeat ######################################

# Configure monitors
heartbeat.monitors:
- type: http

  # List or urls to query
  urls: ["https://xxxx-yyyy-corp.com/DigitalSystem/","https://aaaaaa-bbbbbb.corp.com/DigitalSystem/"]
# Configure task schedule
  schedule: '@every 60s'

  # Total test connection and data exchange timeout
  #timeout: 16s
```

Hi @Nithani25,

Is it possible that these urls are using self-signed certificates? If that is the case you may want to install them to the system, or add its CA with [`ssl.certificate_authorities`](https://www.elastic.co/guide/en/beats/heartbeat/6.5/configuration-ssl.html#_literal_certificate_authorities_literal).

You can also disable ssl checks with [`ssl.verification_mode: none`](https://www.elastic.co/guide/en/beats/heartbeat/6.5/configuration-ssl.html#_literal_verification_mode_literal).
