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 sure no other VIP had the rule applied and that I was the only one able to access that VIP). I have also seen it not increment after accessing and iRule.
Just wanting to better understand. Thank you.
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.

hoad_312348The event I am using is HTTP_REQUEST. Is this described or defined in the docs anywhere?

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.
