In this video, I explain the various synthetic (or auto-generated) metrics that Prometheus records for every target scrape: up, scrape_duration_seconds, scrape_samples_scraped, scrape_samples_post_metric_relabeling, and scrape_series_added. Where do they come from, what do they mean, and what can you do with them?
