Scenario:

Setup Heartbeat for ELK on Docker to ping the given sites to check if they are up.

Solution:

• Create a folder called heartbeat.Inside it add below dockerfile

ARG ELK_VERSION

FROM docker.elastic.co/beats/heartbeat:${ELK_VERSION}

WORKDIR "/usr/share/heartbeat"

# Auto-Create Kibana Heartbeat Dashboard Tables 
RUN  ./heartbeat setup --dashboards

• Create file heartbeat.yml with following content

heartbeat.monitors:
- type: http
  schedule: '@every 60s'
  urls:
    - http://localsite
    - http://google.com

  check.request:
    method: GET
    headers:
        'Content-Type': 'application/json' 
  check.response:
       status: 200
       

output.elasticsearch:
   hosts: 'elasticsearch:9200'

setup.kibana:
  host: "elasticsearch:5601"

• In docker-compose.yml add below

.....
heartbeat:
     build:
       context: ./heartbeat
       args:
          ELK_VERSION: $ELK_VERSION
     volumes:
      - type: bind
        source: ./heartbeat/config/heartbeat.yml
        target: /usr/share/heartbeat/heartbeat.yml
        read_only: true
     environment:
       - output.elasticsearch.hosts=["elasticsearch:9200"]
     networks:
       - elk
     depends_on:
       - elasticsearch
     restart: always

• Please note X-Pack has security which on by default and so by default ES is not accesible with out creds. So to skip that still using trial license disable security by adding to  elasticsearch.yml below:
• xpack.security.enabled: false 
• Powershell -> docker-compose up -d --force-recreate --no-deps
• Navigate to Kibana -> Uptime to see the metrics.
