Calculating Latency

The iRule is processed for each connection and variables created are connection specific meaning each connection has it's own table of variables that gets cleaned up with the connection closes.

 

 

I'm a bit confused why you are including the CLIENT_ACCEPTED and CLIENT_CLOSED events here. If it's an HTTP connection that is using a KeepAlive connection, then multiple HTTP requests can be made across the same connection but from what you said, you are concerned with the time it takes for each request to go to/from the backend server. If this is the case, then you can just track on all HTTP request/responses, not across the entire connection.

 

 

From what I can see, you can take the iRule I posed in the above referenced Tech Tip and deploy it. It will give you the total requests along with the total request time from which you can derive the time per request to/from the server.

 

 

Maybe I'm missing something...
