ELK - Hearthbeat實作服務監控

Hearthbeat，心跳，顧名思義，Hearthbeat可以用來定時探測服務是否正常運作。

Hearthbeat支援ICMP、TCP 和 HTTP，也支援TLS、身份驗證和代理。

Hearthbeat能夠與Logstash、Elasticsearch和Kibana無縫協作。安裝Hearthbeat，添加需要監控的服務，配置好Elasticsearch和Kibana，即可将結果輸出到Elasticsearch，并在Kibana顯示出來。

Kibana無須再配置Dashboard，直接點選

Uptime

菜單即可看到結果。

Elasticsearch和Kibana的安裝可參考：快速搭建ELK（7.2.0）

下載下傳

curl -L -O https://artifacts.elastic.co/downloads/beats/heartbeat/heartbeat-7.2.0-linux-x86_64.tar.gz
tar xzvf heartbeat-7.2.0-linux-x86_64.tar.gz -C /opt/elk/
           

配置

cd /opt/elk/heartbeat-7.2.0-linux-x86_64/
vi heartbeat.yml
           

比如通過簡單地探測console url來監控Websphere是否正常運作。

監控TCP可參考注釋裡的例子。Schedule表示每10秒監測一次。

# Configure monitors inline
heartbeat.monitors:
- type: http

  # List or urls to query
  urls: ["https://dummy.hostname.net:9043/ibm/console/logon.jsp"]

  # Configure task schedule
  schedule: '@every 10s'

#- type: tcp
  #hosts: ["192.168.1.101:1414"]
  #schedule: '@every 10s'


setup.kibana:

  # Kibana Host
  # Scheme and port can be left out and will be set to the default (http and 5601)
  # In case you specify and additional path, the scheme is required: http://localhost:5601/path
  # IPv6 addresses should always be defined as: https://[2001:db8::1]:5601
  host: "localhost:5601"

output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["localhost:9200"]
           

啟動

chown elk:elk -R /opt/elk/heartbeat-7.2.0-linux-x86_64/
sudo chmod o+rx -R /opt/elk/heartbeat-7.2.0-linux-x86_64/

sudo -u elk ./heartbeat setup

sudo -u elk nohup ./heartbeat -e &
           

驗證

• Open http://localhost:5601/
• Go to Uptime.
• 重新開機被監控服務
