how to gather how many IPs hit the url and how many times

[root@ve1023:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.79:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when CLIENT_ACCEPTED {
        table set -subtable "iplist" [IP::client_addr] "ignored"

        set reqno [table incr "reqs:[IP::client_addr]"]
        table set -subtable "reqrate:[IP::client_addr]" $reqno "ignored" indefinite 60
}

when HTTP_REQUEST {
        if {[string tolower [HTTP::uri]] equals "/stats"} {
                set stats "ip,request number\n"
                foreach ip [table keys -subtable "iplist"] {
                        append stats "$ip,[table keys -count -subtable "reqrate:$ip"]\n"
                }
                HTTP::respond 200 Content $stats
        }
}
}
