We consider each TCP CONNECT packet to be a Request when using the SOCKS proxy. 
 
For database connections, generally your application is going to keep those alive for a very long time.  This will result in very few requests through QuotaGuard. 

We will log every time you hit 1MB of bandwidth through the proxy.  

So if you use enough bandwidth, you should start to see the bandwidth numbers go up and show up in the log viewer.
