-The following data sources are officially supported: [Graphite]({{< relref "features/datasources/graphite.md" >}}), [InfluxDB]({{< relref "features/datasources/influxdb.md" >}}), [OpenTSDB]({{< relref "features/datasources/opentsdb.md" >}}), [Prometheus]({{< relref "features/datasources/prometheus.md" >}}), [Elasticsearch]({{< relref "features/datasources/elasticsearch.md" >}}), [CloudWatch]({{< relref "features/datasources/cloudwatch.md" >}}).
