Nimbostratus"Total Executions" statistic for an iRule?
I'm looking for an (in-depth) explanation of the "Total Executions" column under statistics for iRules.
I have seen that number increment by 6, for example, after accessing an iRule (yes, I am ...
It is the number of times the F5 has triggered an iRule. The event used by the iRule determines how often it will be executed.

Yes and no. Its described in the iRule training but it requires an understanding of protocol behaviour as well. HTTP_REQUEST can be triggered many times in a single connection as HTTP/1.1 specification keep connections open for a time so the browser can reuse them for subsequent requests. A single web browser can have multiple connections.

If you not seeing consistent statistics the turn on developer mode in your browser and disable caching. Refreshes of a page will pull images out of the local browser cache and they wont request it from the F5.

Thank you. I guess the only other follow-up question I have is ... can the iRule be accessed and yet the execution count not be incremented? For example if "event disable all" is called.

Event disable will turn off all future events for that individual connection. However to execute that command the iRule must at least have been executed once.
