title: Prometheus setting for scrape_interval
body: <p>I'm trying to use Prometheus and VictoriaMetrics to collect data and when configuring my server prometheus.yml there is one line:</p>
  
  <pre><code>scrape_interval: 15s  # How frequently to scrape targets by default.
  </code></pre>
  
  <p>Does this mean my search result might be delayed by 15s?</p>
