With the recent release (v188.8.131.52), the F5 Management Pack has an improved responsiveness to device statistics collection. By default, the timer interval for collecting stats is set to 30 seconds, but this value now can be easily overwritten in the (SCOM 2007) F5 Management Pack, as a rule override. The lowest value the timer interval could be set, theoretically, is 3 seconds. There is an internal safeguard in the F5 device (Big-IP) against lowering this threshold and putting unnecessary load on the device CPU, for collecting stats. In the real world stats would come, on average, every 5-10 seconds, even with the 3 second interval setting.
