我正在使用 this prometheus helm chart 。
我想知道是否可以设置 prometheus 操作符来自动监控集群或命名空间中的每个服务,而不必为每个服务创建 ServiceMonitor
。
使用当前设置,当我想监视服务时,我必须创建一个带有 ServiceMonitor
标签的 release: prometheus
。
编辑:
带有 monitoring: "true"
标签的服务
apiVersion: v1
kind: Service
metadata:
name: issue-manager-service
labels:
app: issue-manager-app
monitoring: "true"
spec:
selector:
app: issue-manager-app
ports:
- protocol: TCP
name: http
port: 80
targetPort: 7200
“包罗万象”的服务监视器:apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
name: service-monitor-scraper
labels:
release: prometheus
spec:
endpoints:
- port: metrics
interval: 30s
path: /metrics
jobLabel: monitoring
namespaceSelector:
any: true
selector:
matchLabels:
monitoring: "true"
最佳答案
仅当您在所有服务上都有一个共同的标签时
# for example:
org: "my-company"
# or
monitoring: "true"
# or
app.kubernetes.io/managed-by: "Helm" # <- in most cases this represents all
然后定义一个单一的、跨命名空间的 ServiceMonitor
,它涵盖所有标记的服务:apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
name: common-monitor
namespace: monitoring
spec:
endpoints:
- port: metrics
interval: 30s
path: /metrics
jobLabel: monitoring
namespaceSelector:
any: true # <- important
selector:
matchLabels:
monitoring: "true" # <- should match what you've chosen as common
然后,为了确保 Prometheus Operator 发现了这个 ServiceMonitor
,您可以:ServiceMonitor
:https://github.com/prometheus-community/helm-charts/blob/4164ad5fdb6a977f1aba7b65f4e65582d3081528/charts/kube-prometheus-stack/values.yaml#L2008 serviceMonitorSelector
https://github.com/prometheus-community/helm-charts/blob/4164ad5fdb6a977f1aba7b65f4e65582d3081528/charts/kube-prometheus-stack/values.yaml#L1760 ServiceMonitor
Prometheus Operator 和 ServiceMonitor 之间的这种额外显式链接是有意完成的 - 这样,如果您的集群上有 2 个 Prometheus 实例(例如 Infra 和 Product),您可以将哪个 Prometheus 将哪些 Pod 分配到其抓取配置中。
从您的问题来看,听起来您已经有一个基于
serviceMonitorSelector
标签的 release: prometheus
- 尝试将其添加到您的全能 ServiceMonitor
中。关于kubernetes - Prometheus:监控所有服务而不为每个服务创建ServiceMonitor?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/64445937/
