Prometheus+Grafana+AlertManager监控平台搭建

Docker搭建并配置Prometheus

Docker拉取并配置Grafana

Docker安装并配置Node-Exporter

Docker安装并配置cAdvisor

Docker安装并运行Alertmanager

新建SpringBoot项目

为Prometheus提供指标

新建项目，引入依赖

java 复制代码

<!--用于导出prometheus系统类型的指标数据-->
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
    <version>1.9.8</version>
</dependency>

新建接口，运行程序

Prometheus配置文件中已添加该项目地址，运行后到Prometheus页面中查看连接情况

成功

推送指标到pushgateway

引入依赖

java 复制代码

<dependency>
    <groupId>io.prometheus</groupId>
    <artifactId>simpleclient</artifactId>
    <version>0.12.0</version>
</dependency>
<dependency>
    <groupId>io.prometheus</groupId>
    <artifactId>simpleclient_pushgateway</artifactId>
    <version>0.12.0</version>
</dependency>

新增push接口，用于推送指标（job=B,instance=A）到Pushgateway

java 复制代码

@GetMapping("push")
public void executeBatchJob(){
    try{
        String url = "192.168.251.44:9091";
        CollectorRegistry registry = new CollectorRegistry();
        Gauge guage = Gauge.build("my_custom_metric11", "This is my custom metric.").create();
        guage.set(1.22);
        guage.register(registry);
        PushGateway pg = new PushGateway(url);
        Map<String, String> groupingKey = new HashMap<String, String>();
        groupingKey.put("instance", "A");
        pg.pushAdd(registry, "B", groupingKey);
    } catch (Exception e){
        e.printStackTrace();
    }
}

运行后调用接口，访问Pushgateway
