Prometheus - 不收集 Django 应用指标

Question

我在运行我的 Django 应用程序的同一台服务器上安装了 Prometheus。我正在尝试使用 API 检索指标，并且 curl 响应的格式似乎正确。

API（网址和视图）：

`ROUTER.register('organization_metrics', simulation.views.OrganizationViewSet, basename='organization_metrics')


class OrganizationViewSet(viewsets.ViewSet):
    renderer_classes = [StaticHTMLRenderer]
    def list(self, request):
        organizations = ["org1", "org2", "org3"] # Replace with your own data
        
        # Create a new CollectorRegistry object
        registry = CollectorRegistry()

        # Create a new Counter metric to track the number of organizations
        #org_counter = Counter('organizations_total', 'Total number of organizations', registry=registry)
        org_counter = Counter('organizations_total', 'Total_number_of_organizations', ['org_name'], registry=registry)


        # Increment the counter for each organization
        for org in organizations:
            org_counter.labels(org_name=org).inc()
           # org_counter.inc()

        # Generate the Prometheus format response
        #response_data = generate_latest(registry)

        # Return the response with the content type 'text/plain'
        logging.info('here I am')        
        #return Response(response_data, content_type='text/plain')
        return (
            Response(
                generate_latest(registry),
                status=status.HTTP_200_OK,
                content_type='text/plain',
            )
        )`

Curl response looks good and in right format:

`curl --request GET http://localhost:8070/api/v1/organization_metrics/ -H 'Accept: text/html'
# HELP organizations_total Total_number_of_organizations
# TYPE organizations_total counter
organizations_total{org_name="org1"} 1.0
organizations_total{org_name="org2"} 1.0
organizations_total{org_name="org3"} 1.0
# TYPE organizations_created gauge
organizations_created{org_name="org1"} 1.6776296973446844e+09
organizations_created{org_name="org2"} 1.6776296973447082e+09
organizations_created{org_name="org3"} 1.6776296973447242e+09`

在我的 prometheus.yml 文件中，我包含了相关的 scrape_configs：

`  - job_name: 'myapp-organization-metrics'
    scrape_interval: 6s
    metrics_path: '/api/v1/organization_metrics/'
    static_configs:
      - targets: ['localhost:8070']
    scheme: http
    metric_relabel_configs:
      - source_labels: [__name__]
        regex: 'organizations_total|organizations_created'
        action: keep
`

在 django 日志文件中，我看到我们每 6 秒到达一次“我在这里” 除了普罗米修斯，没有人称这个 api。 然而，尽管如此，我还是无法在 http://localhost:9090/metrics 响应中找到 organizations_total 和 organizations_created 的指标。

如有任何帮助，我们将不胜感激。

谢谢。
