can you add log command something like this? 

[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when CLIENT_ACCEPTED {
   TCP::collect 2
}

when CLIENT_DATA {
   set msid [TCP::payload 2]
   binary scan $msid H* msid_hex
   log local0. "\$msid: $msid"
   log local0. "\$msid_hex: $msid_hex"
   TCP::release
}
}

[root@ve1023:Active] config  cat /var/log/ltm
