+### Graphite <a id="addons-graphing-graphite"></a>
+
+[Graphite](https://graphite.readthedocs.org/en/latest/) is a time-series database
+storing collected metrics and making them available through restful apis
+and web interfaces.
+
+Graphite consists of 3 software components:
+
+* carbon -- a Twisted daemon that listens for time-series data
+* whisper -- a simple database library for storing time-series data (similar in design to RRD)
+* graphite webapp -- a Django webapp that renders graphs on-demand using Cairo
+
+You need to install Graphite first, then proceed with configuring it in Icinga 2.
+
+Use the [GraphiteWriter](14-features.md#graphite-carbon-cache-writer) feature
+for sending real-time metrics from Icinga 2 to Graphite.
+
+    # icinga2 feature enable graphite
+
+A popular alternative frontend for Graphite is for example [Grafana](https://grafana.org).
+
+Integration in Icinga Web 2 is possible by installing the official [graphite module](https://icinga.com/docs/graphite/latest/).

-By enabling the [DB IDO](14-features.md#db-ido) feature you can use the
-[Icinga Reporting package](https://icinga.com/docs/icinga1/latest/en/reporting.html).
+This community module displays host objects as markers on openstreetmap in Icinga Web 2.
+It uses the data provided by the monitoring module and as such the [DB IDO](14-features.md#db-ido)
+from Icinga 2.
+
+If you configure multiple hosts with the same coordinates, i.e. servers in a datacenter, a clustered view is rendered.
+
+Check the  [Map module docs](https://github.com/nbuchwitz/icingaweb2-module-map) for more details on
+installation, configuration and integration.

+
+The [Icinga 2 dashboard](https://github.com/dnsmichi/dashing-icinga2) is built
+on top of Dashing and uses the [REST API](#icinga2-api) to visualize what's going
+on with your monitoring. It combines several popular widgets and provides development
+instructions for your own implementation.
+
+The dashboard also allows to embed the [Icinga Web 2](https://icinga.com/products/icinga-web-2/)
+host and service problem lists as Iframe.
