# Pi-hole Faster Than Light logs

AxoSyslog can collect logs of the [Pi-hole](https://pi-hole.net/) FTL (Faster Than Light) application.

## Prerequisites

- AxoSyslog version 4.6.0 or later.
- Install the `axosyslog-scl` package on [Debian/Ubuntu](https://axoflow.com/docs/axosyslog-core/4.28/install/debian-ubuntu/index.md). On [RHEL and compatible distributions](https://axoflow.com/docs/axosyslog-core/4.28/install/rhel-fedora-almalinux/index.md), the SCL files are part of the `axosyslog` base package.

  Your configuration must also contain `@include "scl.conf"`, which the default configuration file already does. If the SCL files are missing, AxoSyslog fails to start with an [`unexpected LL_IDENTIFIER` error](https://axoflow.com/docs/axosyslog-core/4.28/chapter-troubleshooting-syslog-ng/unexpected-ll-identifier/index.md).

  ```shell
  @include "scl.conf"
  ```

  The `pihole-ftl()` driver is a reusable configuration snippet (SCL). For details on using or writing such configuration snippets, see [Reusing configuration blocks](https://axoflow.com/docs/axosyslog-core/4.28/chapter-configuration-file/large-configs/config-blocks/index.md). You can find its source in [scl/pihole/pihole.conf](https://github.com/axoflow/axosyslog/blob/main/scl/pihole/pihole.conf) on GitHub.

## Configuration

```shell
source s_pihole_ftl {
  pihole-ftl();
};
```

By default, the source reads the `/var/log/pihole/FTL.log` file. If the root directory of your Pi-hole installation is different, specify the directory where the FTL.log file is with the `dir()` option. You can find the root log directory by selecting **Tools > Pi-hole diagnosis** in the Pi-hole application. Otherwise, the `pihole-ftl()` source has the same parameters as the [`file()` source](https://axoflow.com/docs/axosyslog-core/4.28/chapter-sources/configuring-sources-file/reference-source-file/index.md).
