## Installation Overview <a id="installation-overview"></a>
### Enabled Features during Installation <a id="installation-overview-enabled-features"></a>
The default installation will enable three features required for a basic
Icinga 2 installation:
* `checker` for executing checks
* `notification` for sending notifications
* `mainlog` for writing the `icinga2.log` file
You can verify that by calling `icinga2 feature list`
[CLI command](11-cli-commands.md#cli-command-feature) to see which features are
enabled and disabled.
```
