What is the maximum scrape_interval in Prometheus : <p>I used Prometheus to measure business metrics like:</p>

<pre><code># HELP items_waiting_total Total number of items in a queue
# TYPE items_waiting_total gauge
items_waiting_total 149
</code></pre>

<p>I would like to keep this data for very long term (5 years retention) and I don't need high frequency in scrape_interval. So I set up <code>scrape_interval: "900s"</code>.</p>

<p>When I check the graph in Prometheus with 60s resolution, it shows that flapping, but it is not true.</p>

<p>The question is, what is the maximum (recommended) scrape_interval in Prometheus?</p>
