HTTP Timeouts, can I use f5 to help figure out why?

We have a pool of servers that are behind a bigip LTM. Every now and then we run into a random nearly impossible to reproduce timeout. For example a random http page won't load, or a random image won't load.

 

 

Is there anything we can enable/futz with our iRules to try and help us figure out where the problem might be?

    The only thing that comes to mind is logging every request and marking the corresponding response from the server as you log it on the LTM. You'd then have to sift through the logs to find the requests that don't have responses following them.

     

     

    This could prove quite arduous, though, if you can't reproduce the issue, since you'd have no idea when to monitor the logs, or where in them to start looking.

     

     

    Unfortunately, as is the case with most seemingly random issues, the fact that they're unreproducable makes them exceedingly hard to track down.
