|carefulSubscription| If this parameter is set to true (default), the RIS server will stream only the data related to our prefix. This is an advanced parameter useful only for research purposes. |
|perMessageDeflate| Enable gzip compression on the connection. |
#### connectorRISDump
It connects to the RIPEstat's BGPlay API and retrieves a RIS dump about the monitored resources. The retrieved dump is 2 hours old, due to limitations on the API side.
#### connectorTest
Connector used for testing purposes, it provokes all types of alerting. Needed to run the tests (`npm run test`) .
