Prometheus

Exporters

Configure jobs to poll prometheus metric exporter endpoints within scrape_configs.
For example, the following config polls metrics from http://localhost:9115/metrics every 5s. 

# /usr/local/etc/prometheus.yml

global:
  scrape_interval: 5s

scrape_configs:
  - job_name:      my-server
    metrics_path:  /metrics   # (default) route to query metrics from
    scheme:        http       # (default) scheme to use for query
    static_configs:
      - targets:
        - localhost:9115      # query this ip-addr/port

Rules

You can configure Rules to either persist or Alerts. 

global:
  evaluation_interval: 15s  # rules evaluated every 15s

alerting:
  alertmanagers:
    - static_configs:
      - targets:
        - alertmanager:9003

rule_files:
  - first_rules.yml
