can monitor server process sts

client_info tell it's noradle server, and its cfg,slot
module is free when wait for request
module is dbu.unit for target plsql servlet
action is in package procedure or standalone for standalone procedure
kill use client_info to match pipe
gateway can set attr-value GAC for process

so we can see env info for the long running servlet
but this time I can not tell which attr/header should be record
so for lower overhead, I just add request start_time
