It is possible to collect the Syslog messages from Ruckus Virtual SmartZone (vSZ).
Based on this document by Ruckus, https://support.ruckuswireless.com/articles/000001194, you can direct Syslog messages to an external Syslog server.
You can use a Syslog source as your Syslog server in a local machine. Just use the IP address of that machine in your Ruckus configuration to forward all Syslog messages via port 514 and install a collector with a Syslog source to listen on port 514.
Alternatively, you can have Ruckus stream the Syslog data to your own local Syslog server and have that Syslog server write the data to a file.
You can then install a collector on that machine with a local file source to read the data from that file.
