利用 Heartbeat 监控

heartbeat 用来定时探测服务是否正常运行。支持ICMP、TCP 和 HTTP，也支持TLS、身份验证和代理。

1、下载并安装

root@web01:~# wget https://mirrors.tuna.tsinghua.edu.cn/elasticstack/7.x/apt/pool/main/h/heartbeat-elastic/heartbeat-7.17.8-amd64.deb

root@web01:~# dpkg -i heartbeat-7.17.8-amd64.deb

# 准备需要监控的服务httpd
root@web01:~# apt -y install apache2

2、修改配置

官方参考

# heartbeat.yml
heartbeat.monitors:
- type: icmp
 id: ping-myhost
 name: My Host Ping
 hosts: ["myhost"]
 schedule: '*/5 * * * * * *'
- type: tcp
 id: myhost-tcp-echo
 name: My Host TCP Echo
 hosts: ["myhost:777"] # default TCP Echo Protocol
 check.send: "Check"
 check.receive: "Check"
 schedule: '@every 5s'
- type: http
 id: service-status
 name: Service Status
 service.name: my-apm-service-name
 hosts: ["http://localhost:80/service/status"]
 check.response.status: [200]
 schedule: '@every 5s'
heartbeat.scheduler:
 limit: 10

时间格式

Seconds        No           0-59              * / , -
Minutes        Yes          0-59              * / , -
Hours          Yes          0-23              * / , -
Day of month   Yes          1-31              * / , - L W
Month          Yes          1-12 or JAN-DEC   * / , -
Day of week    Yes          0-6 or SUN-SAT    * / , - L #
Year           No           1970–2099         * / , -

范例

root@web01:~# vim /etc/heartbeat/heartbeat.yml
heartbeat.monitors:
- type: http
  # Set enabled to true (or delete the following line) to enable this example monitor
  enabled: true
  # ID used to uniquely identify this monitor in elasticsearch even if the config changes
  id: my-monitor
  # Human readable display name for this service in Uptime UI and elsewhere
  name: My Monitor
  # List or urls to query
  urls: ["http://192.168.1.105:80"]
  # Configure task schedule
  schedule: '@every 10s'

- type: icmp
  id: ping-myhost
  name: My Host Ping
  hosts: ["192.168.1.105"]
  schedule: '*/5 * * * * * *'

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: "192.168.1.104:5601"

output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["192.168.1.101:9200"]

3、启动服务

root@web01:~# systemctl enable --now heartbeat-elastic.service 

4、head 插件查看索引

5、通过 Kibana 查看收集的性能指标

6、停止监控的服务再观察 Kibana

root@web01:~# systemctl stop apache2.service 

7、利用 Kibana 将 Heartbeat 的数据进行可视化
