There are a few things to consider in this request.

  1. Session count is a TCP value, so it doesn't necessarily equate to the number of users accessing the system, but rather the number of TCP sessions open.

  2. There are several ways to get metrics from a BIG-IP. There are third party tools (Splunk, System Center, etc.), and several different formats (syslog, SNMP, etc.). Each of these tools can reach in and get the data (via iControl), or receive and aggregate the data (via SNMP, syslog, etc.).

  3. At a minimum, if you just wanted to send this raw TCP data to a server every hour, you could simply create a script that performs a TMSH function 

    tmsh show /ltm pool local-pool members { 10.70.0.1:80 } |grep "|   Current Connections" |awk -F" " '{ print $4 }'

and sends that to a remote server via cURL.
