배치(잡) 만들기

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
    compile('io.prometheus:simpleclient_pushgateway:0.6.0')
}

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

public class SampleBatch {
    public static void main(String[] args) {
        String url = "localhost:9091";
        PushGateway pushGateway = new PushGateway(url);

        long now = System.currentTimeMillis();

        // メトリクスを収集（ここでは起動時間としてシステムミリ秒をセット）
        CollectorRegistry registry = new CollectorRegistry();
        Gauge lastStartAt = Gauge.build()
                .name("batch_start_time")
                .help("batch start time")
                .register(registry);
        lastStartAt.set(now);

        // メトリクスにタグを設定
        Map<String, String> key = new HashMap<>();
        key.put("tagName", "tagValue");

        try {
            // メトリクスを登録
            pushGateway.pushAdd(registry, "sample-batch", key);
        } catch (IOException e) {
            // 例外処理
            e.printStackTrace();
        }
    }
}
