Starting with version 4.6.0, AxoSyslog can collect logs of the Pi-hole FTL (Faster Than Light) application.
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.
The pihole-ftl() driver is actually a reusable configuration snippet. For details on using or writing such configuration snippets, see Reusing configuration blocks. You can find the source of this configuration snippet on GitHub.
