## <a id="addons"></a> Addons
### <a id="addons-graphing-reporting"></a> Graphing Addons
#### <a id="addons-graphing-pnp"></a> PNP
[PNP](http://www.pnp4nagios.org) must be configured using the
[bulk mode with npcd and npcdmod](http://docs.pnp4nagios.org/pnp-0.6/modes#bulk_mode_with_npcd_and_npcdmod)
hence Icinga 2's [PerfdataWriter](#performance-data) acts as npcdmod. NPCD will collect
the rotated performance data files.
#### <a id="addons-graphing-pnp"></a> inGraph
[inGraph](https://www.netways.org/projects/ingraph/wiki) requires the ingraph-collector addon
to be configured to point at the perfdata files. Icinga 2's [PerfdataWriter](#performance-data) will
write to the performance data spool directory.
#### <a id="addons-graphing-pnp"></a> Graphite
There are Graphite addons available for collecting the performance data files as well. But
natively you can use the [GraphiteWriter](#graphite-carbon-cache-writer) feature.
#### <a id="addons-reporting"></a> Icinga Reporting
By enabling the DB IDO feature you can use the Icinga Reporting package.
### <a id="addons-visualization"></a> Visualization
#### <a id="addons-visualization-nagvis"></a> NagVis
By using either Livestatus or DB IDO as a backend you can create your own network maps
based on your monitoring configuration and status data using [NagVis](http://www.nagvis.org).
### <a id="addons-web-interfaces"></a> Web Interfaces
As well as the Icinga supported web interfaces (Classic UI 1.x, Web 1.x, Web 2) there are a
number of community provided web interfaces too:
* [Thruk](http://www.thruk.org) based on the [Livestatus](#livestatus) feature
## <a id="plugins"></a> Plugins
You can find plugins (additional to the ones at [Monitoring Plugins](https://www.monitoring-plugins.org)) over at
[Monitoring Exchange](#https://www.monitoringexchange.org)
More details on the plugins can also be found on the Icinga Wiki at https://wiki.icinga.org
## <a id="plugin-api"></a> Plugin API
Currently Icinga 2 supports the native plugin API specification from the `Monitoring Plugins`
project.
The `Monitoring Plugin API` is defined in the [Monitoring Plugins Development Guidelines](https://www.monitoring-plugins.org/doc/guidelines.html).
There are no output length restrictions using Icinga 2. This is different to the
[Icinga 1.x plugin api definition](http://docs.icinga.org/latest/en/pluginapi.html#outputlengthrestrictions).
