1、增加参数重启prometheus

修改 prometheus启动参数

- "--enable-feature=remote-write-receiver"

重启 prometheus

2、下载案例

GitHub - bprasen/remotewrite

3、迁移

将案例中的代码复制到springboot/springcloud中

pom中增加

<!-- prometheus remote write 依赖 -->
<!-- https://mvnrepository.com/artifact/com.google.protobuf/protobuf-java -->
<dependency>
    <groupId>com.google.protobuf</groupId>
    <artifactId>protobuf-java</artifactId>
    <version>3.11.1</version>
</dependency>

<!-- https://mvnrepository.com/artifact/com.google.protobuf/protobuf-java-util -->
<dependency>

</dependency>

4、测试

        Map<String, String> tags = new HashMap<>();
        tags.put("a", "b1");

        MetricPoint mp = new MetricPoint();
        TasksConfig.Item conf = new TasksConfig.Item();
        conf.setLabels(tags);
        conf.setMetric("metric_testAB");
        mp.setTime(System.currentTimeMillis() - 60*1000);
        mp.setValue(56);
        mp.setConf(conf);

        Map<String, String> tags2 = new HashMap<>();

        conf2.setLabels(tags2);
        conf2.setMetric("metric_testAB");
        mp2.setValue(150);

        prometheusService.remoteWrite(Lists.newArrayList(mp, mp2));
    }
