我正在使用Prometheus从我的广告连播中抓取指标。我感兴趣的应用程序通过提供访问权限的一项服务被复制了两次。 Prometheus使用此服务来抓取指标。在我的应用中,指标设置如下:
import * as Prometheus from 'prom-client';
const httpRequestDurationMicroseconds = new Prometheus.Histogram({
name: 'transaction_amounts',
help: 'Amount',
labelNames: ['amount'],
buckets: [0, 5, 15, 50, 100, 200, 300, 400, 500, 10000],
});
const totalPayments = new Prometheus.Counter('transaction_totals', 'Total payments');
我正在使用头盔安装Prometheus,并且抓取配置如下:
prometheus.yml:
rule_files:
- /etc/config/rules
- /etc/config/alerts
scrape_configs:
- job_name: prometheus
static_configs:
- targets:
- localhost:9090
- job_name: transactions
scrape_interval: 1s
static_configs:
- targets:
- transaction-metrics-service:3001
我可以看到普罗米修斯内部的指标,但这似乎只是来自一个荚。例如,在Prometheus中,当我查询transaction_totals
时会给出:
我认为instance
标签不能唯一标识我的豆荚。我应该怎么做才能查询所有吊舱?

请尝试使用Prometheus提供的static_config
Kubernetes Service Discovery,而不是使用仅刮刮一台主机的kubernetes_sd_configs
。
您的配置文件如下所示:
- job_name: 'kubernetes-pods'
kubernetes_sd_configs:
- role: pod
relabel_configs:
# only scrape when annotation prometheus.io/scrape: 'true' is set
- source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_scrape]
action: keep
regex: true
- source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_path]
action: replace
target_label: __metrics_path__
regex: (.+)
- source_labels: [__address__, __meta_kubernetes_pod_annotation_prometheus_io_port]
action: replace
regex: (.+):(?:\d+);(\d+)
replacement: ${1}:${2}
target_label: __address__
- action: labelmap
regex: __meta_kubernetes_pod_label_(.+)
- source_labels: [__meta_kubernetes_namespace]
action: replace
target_label: kubernetes_namespace
- source_labels: [__meta_kubernetes_pod_name]
action: replace
target_label: kubernetes_pod_name
,然后将注释添加到您的Kubernetes部署yaml配置中,如下所示:
kind: Deployment
...
spec:
template:
metadata:
annotations:
prometheus.io/scrape: "true"
prometheus.io/port: "<< PORT OF YOUR CONTAINER >>"
您会看到一个full working example here。

在您的服务中添加普罗米修斯注释,因为舞会只会刮擦以下服务:
prometheus.io/scrape: "true"
批注prometheus.io/port: "<exporter_port_here>"
批注这是一个official example
刮掉的豆荚本身可能就是普罗米修斯
