# GBDS Notifier

## Configuration File

The Notifier's configuration parameters are defined in a configuration file containing all parameters and their respective values. Omitted parameters assume default values. This section describes the properties of the configuration file.

### File Location

The configuration file is located at: `/etc/griaule/conf/notifier.properties`.

### File Properties

The configuration file must follow some requirements to be correctly interpreted by the GBDS. These requirements are:

1. The file name and its location must be exactly the same as those mentioned in the section [File Location](#localizacao-do-arquivo)
2. There must be exactly one configuration parameter per line.
3. Each configuration parameter must have the form `{parameter}={value}`, without line breaks;
4. Each value must be separated by a comma when assigned to a single parameter.
