基本入门

运行windows exporter,他会在端口9182监听。用telnet测试端口是否打开

配置G:\sw\prometheus-2.21.0-rc.0.windows-amd64\prometheus.yml,加入

# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:9090']

  - job_name: 'jaeger'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:14269']

  - job_name: 'windows'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:9182']    

运行G:\sw\prometheus-2.21.0-rc.0.windows-amd64\prometheus.exe

用chrome打开http://localhost:9090/

如何搭配grafana打造高逼格监控平台(done)

https://blog.51cto.com/youerning/2050543

访问grafana, http://<服务器IP>:3000
默认用户名密码:admin/admin

为grafana添加Prometheus数据源

https://www.jianshu.com/p/8d2c020313f0

安装并启动Grafana后,浏览器输入 IP:3000 来访问Grafana,管理员账号密码默认是admin/admin。首次登陆会让你修改管理员密码,然后就可以登录查看了。

在界面左边是一竖排选项,选择设置图标中的Data Source,添加Prometheus的数据源,URL就填上面你给Prometheus Server设置的ip+端口号就行了,如果没改过且在本机运行的话,那就是localhost:9090。

此时可以添加dashboard,也就是监控面板了,在刚配好的Prometheus Data Source的设置中有一个标签就是dashboard,我们导入Prometheus 2.0 Stats这个面板,就能看到我们Prometheus的一些基本监控情况了,这其实就是导入了一个别人写好的面板配置,并且连接我们自己Prometheus的监控数据做展示。

还记得我们上面还运行了一个node exporter吧,现在我们展现一下这个监控信息,左边竖排点击加号图标中的Import,来导入其他别人写好的面板。在Grafana的官方面板页面其实可以看到很多别人配置好的面板,我们找到自己想要的面板,比如这个node exporter的:

复制右边那个面板ID,然后在Import界面输入ID,Load后配置好数据源为我们的Prometheus,就可以出现我们自己机器的状态监控面板了,很炫酷吧。

这个面板需要安装一个饼图的插件(页面上有说明),安装Grafana插件的方法为:

// 进入Grafana/bin目录
./grafana-cli plugins install [插件名]
// 安装成功后重启Grafana

如何监控windows系统(done)

一、安装wmi-exporter

首先在需要监控的Windows机器上安装wmi_exporter。wmi_exporter下载地址:https://github.com/martinlindhe/wmi_exporter/releases

img

下载后,双击即可完成安装。

完成安装后,会自动创建一个开机自启的服务

img

img

验证服务是否启动,默认wmi-exporter端口为9182

浏览器访问 http://192.168.56.1:9182/metrics (Windows系统IP地址:9182端口),显示数据,则服务开启成功。

二、修改Prometheus配置

进入Prometheus的安装文件夹,打开Prometheus配置文件

#  cd /usr/local/prometheus
#  vim prometheus.yml

在scrape_configs标签下,添加以下内容,配置监控

- job_name: 'Windows'
    static_configs:
    - targets: ['192.168.56.1:9182']
      labels:
        instance: Windows

以下是Prometheus.yml 文件全部内容

[复制代码](javascript:void(0)😉

# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:9090']

  - job_name: 'Linux'
    static_configs:
    - targets: ['192.168.56.201:9100']
      labels:
        instance: Linux

  - job_name: 'Windows'
    static_configs:
    - targets: ['192.168.56.1:9182']
      labels:
        instance: Windows

[复制代码](javascript:void(0)😉

保存退出,重启Prometheus服务

#  systemctl restart prometheus

浏览器访问 http://192.168.56.200:9090/targets 查看监控信息

img

可以看到,Windows机器已经加入进来。

三、配置Grafana

添加dashboard

Grafana官方为我们提供了很多dashboard页面,可直接下载使用。浏览器访问 https://grafana.com/grafana/dashboards 下载所需要的dashboard页面

此处我们使用Windows 监控的dashboard,dashboard Id为:10467

img

然后打开我们的Grafana监控页面,打开dashboard的管理页面

img

点击【import】按钮

img

然后将我们刚才的dashboard Id (10467) 复制进去

img

Grafana会自动识别dashboard Id 。

然后点击【change】按钮,生成一个随机的UID,然后点击下方输入框,选择我们之前创建的数据源Prometheus,最后点击【Import】按钮,即可完成导入。

img

导入成功后,会自动打开该Dashboard,即可看到我们刚才设置好的Windows监控

img

至此Prometheus监控Windows机器,配置完成。

如何设置alert?
