Prometheus - Collector

Scale Counter Graph


A collector is a metrics collector and is embedded in the prometheus server.



The scrape_configs block of the prometheus.yml file controls what resources Prometheus monitors. The below example shows a single job, called prometheus, which scrapes the metrics (time series data) exposed by an exporter (below this is the internal Prometheus server exporter)


  - job_name: prometheus
      - targets: ['localhost:9090']
    scheme: 'https'
