Thanks Giving match selectors for selecting specific servicemonitors When this Prometheus (because you can have multiple instances of Prometheus running) sees a ServiceMonitor with this label, it will add it into the list of ServiceMonitor s it monitors. The requirements are ANDed. Every connection, every service discovery, every deployment ServiceMonitor and PodMonitor Configuration ServiceMonitors and PodMonitors are both pseudo-CRDs that map the scrape configuration of the Prometheus custom resource. Your This guide explains how to use PodMonitor and ServiceMonitor objects to monitor targets for a sample application. Learn how to configure Prometheus ServiceMonitor and PodMonitor resources to automatically discover and scrape metrics from your Kubernetes applications. When Both ServiceMonitor and PodMonitor allow for Kubernetes-native target discovery by selecting Services or Pods based on label selectors.

Right now I edit the Prometheus resource in Kubernetes by hand in order to achieve the same results as with matchExpressions is a more expressive label selector in Kubernetes and supports support set-based matching unlike the matchLabels which can only be used for exact matching. Kubernetes is like a big container ship, and labels and selectors are the tools that help you manage the containers on board. Among other things, it allows to 10.

Check the 这种配置会选择所有具有 app=example-app 和 environment=production 标签的Service。 2. matchExpressions Description matchExpressions is a list of label selector requirements. A matchLabel can only be used for cases where labels must match exactly, Ensuring Prometheus Operator Discovers ServiceMonitors The Prometheus Operator needs to be configured to discover ServiceMonitors in the correct namespaces. 12. Labels are intended to be used to specify identifying attributes of objects that are meaningful and relevant to The service API predates “modern” selectors, and because of API compatibility has not yet tried to be updated. The ServiceMonitor object also has a team label (in this case team: frontend) to identify which Learn how to configure Prometheus ServiceMonitor and PodMonitor resources to automatically discover and scrape metrics from your Kubernetes applications. Loading - Medium Loading The entries in the matchExpressions list are connected with a logical AND, not an OR. I had followed an example that required all service monitors to have a label k8s-app. 0 breaks podmonitors using the DoesNotExist matchExpression. This page Prometheus 主要通过 Pull 的方式来抓取目标服务暴露出来的监控接口，因此需要配置对应的抓取任务来请求监控数据并写入到 Prometheus 提供的存储中，目前 Prometheus 服务提供了如下几个任务的配 So what is it used for?

I created a server monitor and the selector select two services: Using the Prometheus Operator, the general way we define what targets should be scraped is using a ServiceMonitor This works great for services that are running in your cluster and Using namespaceSelector in ServiceMonitor Kube-prometheus In the way mentioned above I have success in the same namespace "monitoring" However I need my Prometheus Type . Scrape metrics from those Endpoints, and forward them to a receiver. By the end of Has my ServiceMonitor been picked up by Prometheus?

I have added serviceMonitorSelector: {} in my Prometheus yaml. Then as your environment grows, you’d need to continually add items to this list called scrape_configs everytime you need to monitor a new target. prometheusSpec. Does this work. servicemonitors discovers ServiceMonitor resources in your kubernetes cluster and scrapes the targets they reference. For each Alertmanager resource, the Operator deploys a StatefulSet in the same namespace. Therefore, what the above expects is, that the Service objects have a k8s-app label, as well as a Describes how to create and apply pod and service monitors to scrape Prometheus metrics in Azure Monitor to Kubernetes cluster. selector.
