operator count_values expects a label string key for each new metrics created (per different values). NET library for instrumenting your applications and exporting metrics to Prometheus. The example Prometheus queries thus far have only used labels that were exported directly by the metrics endpoint being scraped (standard Prometheus metric labels) but the labels associated with a Kubernetes service can be combined with the metric labels exposed by scrape targets and can then also be used within Prometheus’ query language. Prometheus should be familiar to you if you have read my earlier articles about docker motioning. . Apr 23, 2018 Prometheus comes with its own query language called PromQL, Each metric only has the pod_name but missing the pod labels, this means that we don't query, we could use that as the joining element on both queries.

Query identifier DevOps Stack Exchange is a question and answer site for software engineers working on automated testing, continuous delivery, service integration and monitoring, and building SDLC infrastructure. The reason for using a new label is the series would no longer be unique if we just overwrote the "group" label, and the sum wouldn't work. However, having these labels available means it is possible to segment the metrics in whatever way is required to analyze the data.

You can use the argument list of group_left to include extra labels from the right operand (parentheses and indents for clarity): The result is propagated into the result vector with the grouping labels becoming the output label set. 4. Each distinct metric_name & label combination is called a time-series . Indeed, all Prometheus metrics are time based data. This applies especially for data stores like Prometheus. Each counter has a label zone which is the zonename used for the request/ response. # * this will scrape every container in a pod with `prometheus. It offers a global view of Prometheus time series data that includes data in long-term storage, greatly expanding the usefulness of PromQL for analytical purposes.

Prometheus is a monitoring solution that gathers time-series based Use Prometheus Vector Matching to get Kubernetes Utilization across any Pod Label. in Kubernetes we get container metrics with a pod_name label from cAdvisor and metrics with a pod label from kube-state-metrics. We also need to keep the pod label to join both metrics on. It is Prometheus’s ability to scale while allowing developers to define and label their alert thresholds that make working with data at scale simpler. For these use cases, Prometheus offers an alternative, called the Pushgateway. com/en/. Metrics as shown in Prometheus UI I've added an example config for Prometheus 1.
