The Data Relay Agent (DRA)
The DRA serves as a gateway between the collectors and the cloud-based metrics server. It can be installed either on the supervisor, on another host on the same network, or on a host outside of a firewall.

Ports in use
The DRA listens for data from the system metrics collectors on port 5001.
Configuration
Configuration file location
DRA configuration is defined in a dra.conf configuration file:
| Operating System | dra.conf location |
|---|
| Windows | C:\ProgramData\pfx\qube\dra.conf |
| Mac | /etc/qube/dra.conf |
| Linux | /etc/qube/dra.conf |
Configuration parameters
System Metrics parameters
- dra_port: local port on which the DRA listens for the system-metrics collectors (default: 5001)
| Note |
|---|
If you change the dra_port, you will also need to change the PFX_DRA_PORT value for the metrics collectors. |
Metered License usage data collector parameters
The DRA must be able to authenticate to the Metered License Server in order for your supervisor to take advantage of metered licensing. The following parameters have no default values,
- mls_user: Metered License Server user login name, for reporting license usage data
- mls_password: MLS user password
Logging
The DRA log location is platform-dependent:
| Operating System | dra.conf location |
|---|
| Windows | C:\ProgramData\pfx\qube\dra.log |
| Mac | /var/log/dralog |
| Linux | /var/log/dralog |
