Timing values cannot be found

I set up an iRule using "timing on" and "timing off" as specified here: https://devcentral.f5.com/wiki/iRules.timing.ashx

I surrounded my entire iRule block with "timing on" as the first line and "timing off" as the last line.

I am not able to find these timing results anywhere however. I thought there would be something under the iRule statistics but I'm not seeing anything related to timing metrics. Can someone please help or shed light on where to look for these values?

Thanks
