Global config contains: scrape_interval - It defines an interval at which Prometheus hits the HTTP endpoint to fetch the metrics. We will imagine that the first two endpoints are production targets, while the third one represents a canary instance. The first one is Prometheus (this is the service name in the docker-compose. Different data structures for scraped Prometheus metrics. It is impossibile for us to use static scrape targets in prometheus config for kubernetes metrics, as things varies all the time in . The Target Scrapes panel shows the frequency of scraping the target, i. My question is: how to add parameter section so proper Prometheus config is generated and module and target parameters are passed correctly? Some example please. The configuration file defines the elements to request, how to scrape them, and where to place the extracted data in the JSON template. Configuring Prometheus Before you can scrape metrics, you might need to configure Prometheus for. Using a file based service discovery allows you to add new or change existing targets dynamically.
