daemon options

The CLI command daemon provides the functionality to start/stop Icinga 2. Furthermore it provides the configuration validation.

-c, --config arg

Using this option you can specify one or more configuration files. Config files are processed in the order they are specified on the command-line.

When no configuration file is specified and the --no-config is not used, Icinga 2 automatically falls back to using the configuration file ConfigDir + /icinga2.conf (where ConfigDir is usually /etc/icinga2).

This option can be used to check if your configuration files contain errors. If any errors are found the exit status is 1, otherwise 0 is returned.
