# Icinga 2 Addons and Integrations <a id="addons"></a>

For an uptodate overview of all integrations and modules,
please visit [https://icinga.com/products/](https://icinga.com/products/).


## Icinga Reporting <a id="addons-reporting"></a>

The [Icinga Reporting Module](https://icinga.com/docs/reporting/latest/)
is the framework and foundation we created to handle data collected
by Icinga 2 and other data providers. By definition Icinga Reporting does not collect
or calculate any data. The framework processes usable data from data providers such as
Icinga’s IDO or Icinga Web 2 modules and makes them available in different formats.

It can display the data directly within the Icinga web interface or export it to PDF,
JSON or CSV format. With scheduled reports you can receive the prepared data periodically
via email.

## Graphs and Metrics <a id="addons-graphs-metrics"></a>

### 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/).

### InfluxDB <a id="addons-graphing-influxdb"></a>

[InfluxDB](https://influxdb.com) is a time series, metrics, and analytics database.
It’s written in Go and has no external dependencies.

Use the [InfluxdbWriter](14-features.md#influxdb-writer) feature
for sending real-time metrics from Icinga 2 to InfluxDB.

```
# icinga2 feature enable influxdb
```

A popular frontend for InfluxDB is for example [Grafana](https://grafana.org).

Integration in Icinga Web 2 is possible by installing the community [Grafana module](https://github.com/Mikesch-mp/icingaweb2-module-grafana).

### PNP <a id="addons-graphing-pnp"></a>

[PNP](https://www.pnp4nagios.org) is a graphing addon.

[PNP](https://www.pnp4nagios.org) is an addon which adds a graphical representation of the performance data collected
by the monitoring plugins. The data is stored as rrd (round robin database) files.

Use your distribution's package manager to install the `pnp4nagios` package.

If you're planning to use it, configure it to use the
[bulk mode with npcd and npcdmod](https://docs.pnp4nagios.org/pnp-0.6/modes#bulk_mode_with_npcd_and_npcdmod)
in combination with Icinga 2's [PerfdataWriter](14-features.md#writing-performance-data-files). NPCD collects the performance
data files which Icinga 2 generates.

Enable performance data writer in icinga 2

```
# icinga2 feature enable perfdata
```

Configure npcd to use the performance data created by Icinga 2:

```
vim /etc/pnp4nagios/npcd.cfg
```

Set `perfdata_spool_dir = /var/spool/icinga2/perfdata` and restart the `npcd` daemon.

There's also an Icinga Web 2 module for direct PNP graph integration
available at [Icinga Exchange](https://exchange.icinga.com/icinga/PNP).

## Visualization <a id="addons-visualization"></a>

### Maps <a id="addons-visualization-maps"></a>

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.

### Business Process <a id="addons-business-process"></a>

Create top-level views of your applications in a graphical editor.
Rules express dependencies between existing hosts and services and
let you alert on application level. Business processes are displayed
in a tree or list overview and can be added to any dashboard.

### Certificate Monitoring <a id="addons-visualization-certificate-monitoring"></a>

Monitor your certificates in an efficient and comfortable way. Be aware of required
actions and view all details at a glance.

### Dashing Dashboard <a id="addons-visualization-dashing-dashboard"></a>

The [Icinga 2 dashboard](https://github.com/dnsmichi/dashing-icinga2) is built
on top of Dashing and uses the [REST API](12-icinga2-api.md#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.

## Log Monitoring <a id="log-monitoring"></a>

Using [Logstash](https://www.elastic.co/guide/en/logstash/current/introduction.html) or
[Graylog](https://www.graylog.org) in your infrastructure and correlate events with your monitoring
is even simpler these days.

* Use the `GelfWriter` feature to write Icinga 2's check and notification events to Graylog or Logstash.
* Configure the logstash `nagios` output to send passive traps to Icinga 2 using the external command pipe.
* Execute a plugin to check Graylog alert streams.

More details can be found in [this blog post](https://icinga.com/2014/12/02/team-icinga-at-osmc-2014/).

* E-Mail ([examples](03-monitoring-basics.md#alert-notifications) provided)
* SMS
* Pager (XMPP, etc.)
* Twitter
* IRC
* Ticket systems
* etc.
