Hi MrB,

 

 

I think you'll have a difficult time logging client info for specific TCP layer issues using iRules. iRules don't provide that level of detail at the TCP layer. SSL errors could be parsed using the SSL:: commands (Click here). For HTTP, you could log a message on the request and one on the response, and parse the ltm log file for unanswered requests. This last option would potentially eat up a lot of resources though.

 

 

For more global stats, you can check the following commands for info:

 

 

b global

 

b virtual VIP_NAME

 

b profile TCP_PROFILE_NAME

 

b profile CLIENTSSL_PROFILE_NAME

 

b profile HTTP_PROFILE_NAME

 

 

Anyone else have ideas on this?

 

 

Thanks,

 

Aaron
