Logging

Cloud Failover Extension logs to /var/log/restnoded.log. The logging level is set in the controls class with possible values of ‘silly’, ‘verbose’, ‘debug’, ‘info’, ‘warning’, and ‘error’. The default value is info. This controls object is sent via a POST /declare.

{
    "controls": {
        "class": "Controls",
        "logLevel": "info"
    }
}

You can see an example of a full declaration in Example Declarations.
