Since it&amp;#x27;s optimized towards purely numeric time series (with arbitrary labeled dimensions), it currently uses an order of magnitude less disk space than InfluxDB for this use case, and I&amp;#x27;ve also heard a few reports of people&amp;#x27;s CPU+IO usage dropping drastically when they switched from InfluxDB to Prometheus for their metrics.&lt;p&gt;As dashboards for Prometheus, you can currently use PromDash (&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;prometheus.io&amp;#x2F;docs&amp;#x2F;visualization&amp;#x2F;promdash&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;prometheus.io&amp;#x2F;docs&amp;#x2F;visualization&amp;#x2F;promdash&amp;#x2F;&lt;/a&gt;), Console HTML templates (&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;prometheus.io&amp;#x2F;docs&amp;#x2F;visualization&amp;#x2F;consoles&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;prometheus.io&amp;#x2F;docs&amp;#x2F;visualization&amp;#x2F;consoles&amp;#x2F;&lt;/a&gt;), or Grafana (&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;prometheus.io&amp;#x2F;docs&amp;#x2F;visualization&amp;#x2F;grafana&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;prometheus.io&amp;#x2F;docs&amp;#x2F;visualization&amp;#x2F;grafana&amp;#x2F;&lt;/a&gt;).&lt;p&gt;Durable long-term storage is still outstanding. Although replication into OpenTSDB and InfluxDB is experimentally there.</text><parent_chain><item><author>tsdbase</author><text>I&amp;#x27;ve hit the same problem and I would like to move back to a SQL data store.
