more fun with iRules

I had some time to play today, and I was interested in the new stats profile offered in 9.2. Here is a rule I put together to get more granular view into the http status codes returned by the server, along with an attached picture of the GUI output. The server in this case is a cisco 2801 with the http server enabled (my lab is weak on the server side!)

class codes_class  {
   "200 c200_OK"
   "201 c201_Created"
   "202 c202_Accepted"
   "203 c203_Partial_Info"
   "204 c204_No_Response"
   "301 c301_Moved"
   "302 c302_Found"
   "303 c303_Method"
   "304 c304_Not_Modified"
   "400 c400_Bad_Request"
   "401 c401_Unauthorized"
   "402 c402_Payment_Required"
   "403 c403_Forbidden"
   "404 c404_Not_Found"
   "411 c411_No_Such_Group"
   "500 c500_Internal_Error"
   "501 c501_Not_Implemented"
   "502 c502_Timed_Out"
}
