 |httpProxy| Defines the HTTP/HTTPS proxy server to be used by BGPalerter and its submodules (reporters/connectors/monitors). See [here](http-proxy.md) for more information. | A string | http://usr:psw@ prxy.org:8080 | No | 
 |volume| Defines a directory that will contain the data that needs persistence. For example, configuration files and logs will be created in such directory (default to "./"). | A string | /home/bgpalerter/ | No | 
 |persistStatus| If set to true, when BGPalerter is restarted the list of alerts already sent is recovered. This avoids duplicated alerts. The process must be able to write on disc inside `.cache/`. | A boolean | true | No |
