如何向普罗米修斯推出一个具有多个指标的量表？网关问题

Question

通过Pushgateway公开具有多个度量的普罗米修斯量表会引发错误“gauge”对象没有属性“\u value”。一旦抛出错误的行被注释，push\u to\u gateway（）抛出

urlopen error [WinError 10061] No connection could be made because the target machine actively refused it

我在尝试进入时没有得到任何响应http://localhost:9091/.

我试图通过HTTP客户端通过标准方法公开度量。然而，python代码将只按需运行，并带有参数。它将运行几秒钟并退出。我决定试试Pushgateway。我试着跟着导游进去https://github.com/prometheus/client_python#exporting-to-a-PUSH网关。我在本地安装了prometheus，并在编辑yaml文件后运行了客户端，将scrape config替换为：

scrape_configs:
 - job_name: pushgateway
   honor_labels: true
   static_configs:
    - targets:
      - localhost:9091

实际代码：

# ( Class attribute )
iv_registry = CollectorRegistry()
# Gauge to be passed to the Prometheus     
iv_gauge = Gauge(ic_gauge_name,
                     ic_gauge_docu_labels, ic_labels_list, registry=iv_registry)


    def __create_gauge(self):
        """Fill gauge to be passed to the prometheus and graffana"""
        try:               
            # Set labels and assign a metric
            self.iv_gauge.labels( label1 = "AAA", label2 =  "BBB", label3 = "CCC"  ).set(4)                          
            self.iv_gauge.labels( label1 = "AAA", label2 =  "BBB", label3 = "DDD"  ).set(0)                          

            # expose in a batch mode
            self.iv_gauge.set_to_current_time() # Does it have to be here? My gauge itself does not have any _value, on matrics with labels store _values
            push_to_gateway('localhost:9091', job='batchA', registry=self.iv_registry)

我希望看到一个具有不同度量的仪表推送到Pushgateway，由Prometheus刮取并用于本地测试，以便能够在localhost上的某个地方显示它http://localhost:8000/通过HTTP服务器公开。请在下面找到样品。

TYPE gauge_name gauge
gauge_name{label1="AAA",label2="BBB",label3="CCC"} 4.0
gauge_name{label1="AAA",label2="BBB",label3="DDD"} 0.0

将以下内容粘贴到Python解释器中：

from prometheus_client import CollectorRegistry, Gauge, push_to_gateway

registry = CollectorRegistry()
g = Gauge('job_last_success_unixtime', 'Last time a batch job successfully finished', registry=registry)
g.set_to_current_time()
push_to_gateway('localhost:9091', job='batchA', registry=registry)
