Even if you store the signal amplitude at 200 Hz, 1 byte per sample (convert to dB before), that would take just 17.3 MByte per day. Peanuts even for an Rpi. You could run the post-processing code each hour, each day, or each hour reducing the data rate to a trivial value. It all depends on how 'real-time' you want the monitoring to be. As Jeff Long pointed out, the advantage of having the post-processing separate from the DSP code is that you can modify or extend it without having to touch Gnuradio code once that works as desired.
