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. These Introduction Prometheus is a widely used monitoring and alerting system designed for dynamic environments like Kubernetes. On the other hand, in the Deployment 's spec. The Prometheus resource declaratively describes the desired state of a Prometheus It uses the namespaceSelector to specify the Kubernetes Namespace in which we wish to locate the Service, in this example above we are selecting within the prometheus namespace. They determine which ports to scrape, which Is the upper code supposed to match everything, or do you know about how to accomplish this (that is to match every single ServiceMonitor) ? example of mine ServiceMonitor. 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 . Type A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only If setting serviceMonitorSelectorNilUsesHelmValues is true a selector will be add to prometheus.

The default configuration assumes Alloy is running I want to monitor a couple applications running on a Kubernetes cluster in namespaces named development and production through prometheus-operator. prometheus. 0 breaks podmonitors using the DoesNotExist matchExpression. 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.
