Question

我想从Ansible中获得站点的响应时间，类似like this，但在Ansible中。我正在使用URI module，但似乎不支持响应时间。

我不喜欢在时间配置文件中使用回调插件，因为我在单个任务中声明了多个url。

我看到Ansible没有返回我需要的值，这是某人已经完成的事情吗？

因此，我创建了a whole playbook out of this request。该剧本本身包括：

检查URL是否提供状态码200
包括从主机到服务器的反应时间
失败时发送Slack消息
将日志发送到Elasticsearch服务器

一个人可以设置一个cronjob来让剧本每隔x秒运行一次。

要回答这个特定问题：

 - hosts: localhost
   vars:
     sites:
       - https://google.com

    - name: verify if all urls works properly
      uri:
        url: "{{ item }}"
        timeout: 10
      with_items: "{{ sites }}"
      register: health_check
      ignore_errors: yes

    # From the docs: The time in sec it took from the start until
    # the first byte was just about to be transferred. This includes
    # time_pretransfer and also the time the server needed to calculate the result.
    - name: response times of sites via cURL via the `starttransfer` method
      shell: 'curl {{ item }} -s -o /dev/null -w  "%{time_starttransfer}\n"'
      register: curl_time
      ignore_errors: True
      args:
        warn: false
      with_items:
        - "{{ sites }}"

    - name: write url and status code to file
      lineinfile:
        line: "{{ start_time }}, {{ item.url }}, {{ item.status }}"
        insertafter: EOF
        dest: "{{ file_path }}"
      with_items: "{{ health_check.results }}"

    - name: append response times to the file
      lineinfile:
        path: "{{ file_path }}"
        backrefs: yes
        regexp: "^(.*{{ start_time }}, .*{{ item.item | replace ('https://', '') | replace ('http://', '')   }}.*)"
        line: '\1, {{ item.stdout }}'
      with_items: "{{ curl_time.results }}"

具有响应时间的uri模块
