If you have access to a counter/timer somewhere, you can sample it at the
beginning of the interrupt service routine and sample it again at the end, and
provided you're confident that it hasn't wrapped around, you can derive the
execution time from the difference of the two samples.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
