Dashboard history question

Regarding 1) anyway;

Date/Time - The current date and time
Total RAM - Total memory available to the system including the HMS and TMM
Free RAM - Total unused memory in the system including the HMS and TMM
Total TMM Memory - Total memory available to TMM only (includes LTM)
Tmm Memory Used - Total unused memory available to TMM only (includes LTM)
User Ticks - see here: http://superuser.com/questions/101183/what-is-a-cpu-tick - this counter relates to user process CPU usage time
System Ticks - as above - this counter relates to system process CPU usage time
Idle Ticks - as above - this counter relates to unused CPU time
Client Bytes In - Bytes received from clients (from a TCP/IP perspective)
Client Bytes Out - Bytes sent to clients (from a TCP/IP perspective)
Server Bytes In - Bytes received from servers (from a TCP/IP perspective)
Server Bytes Out - Bytes sent to servers (from a TCP/IP perspective)
HTTP Compression - size of content that was compressed, before it was compressed
SSL Curr Client Conns - current number of SSL/TLS connections terminated locally using a ClientSSL profile (F5 is server)
SSL Curr Server Conns - current number of SSL/TLS connections to remote/real servers using a ServerSSL profile (F5 is client)
SSL Tot Native Client Conns - current number of SSL/TLS connections terminated locally using a ClientSSL profile (F5 is server) and a native (hardware accelerated) cipher
SSL Tot Common Client Conns - current number of SSL/TLS connections terminated locally using a ClientSSL profile (F5 is server) and compat (OpenSL) cipher
SSL Tot Native Server Conns - current number of SSL/TLS connections to remote/real servers using a ServerSSL profile (F5 is client) and a native (hardware accelerated) cipher
SSL Tot Common Server Conns - current number of SSL/TLS connections to remote/real servers using a ServerSSL profile (F5 is client) and compat (OpenSL) cipher
Tot Client Conns - current total number of TCP/IP client connections - I'm not entirely sure how this figure is derived (do SNAT only connections etc. count?)

If anyone else can clarify that last one I'd be grateful.
