# socket rTorrent's rpc socket (scgi_local) - using scgi_local - needed, when "src" is set to "socket"
# ip rTorrent's ip address - using scgi_port - needed, when "src" is NOT set to "socket"
# port rTorrent's scgi port (scgi_port) - using scgi_port - needed, when "src" is NOT set to "socket"
# category Change graph category
