Prometheus actively scrapes data, stores it, and supports queries, graphs, and alerts, as well as provides endpoints to other API consumers like Grafana or even Graphite itself. Before you begin. The API for the query service is to be compatible with the existing Prometheus codebase for querying and metrics retrieval, in that one should be able to scrape existing instrumented services in the same way, and point a Grafana instance at it, for instance. Instead, Prometheus is a pull-based system that periodically fetches metrics from exporters. The result of an expression can either be shown as a graph, viewed as tabular data in Prometheus's expression browser, or consumed by external systems via the HTTP API. You can quickly plot the result using queries in the Azure portal. There are two types of terms: A single term is a single word such as test or hello. “How to Analyze Your Prometheus Data in SQL” Recap and Resources.

You can configure Prometheus to generate alerts from any valid PromQL query. The intention of this repository is to become a simple place for people to provide examples of queries they've found useful. Prometheus metrics libraries have become widely adopted, not only by Prometheus users, but by other monitoring systems including InfluxDB, OpenTSDB, Graphite, and Sysdig Monitor. The token must be passed with each HTTP request in the Authorization header:. Here I’ll go through an example where I set up Prometheus as Grafana’s source such and then perform the dashboard initialization without using the UI.
