    You have to calculate it by taking the difference between two readings over a period of time.

     

    The downside is that the period of time you pull the stats (Probably every 30-60 seconds) isn't sufficient to know the values that the LTM is using. Because LTM counts SSL transactions every 10ms. The algorithm is to take the TPS. Divide by 100. Then count the number per 10ms interval. If for example you have 500TPS, then you get 5 SSL transactions per 10ms slice. The 11th one is dropped, and a message logged...

     

    FWIW on a 60 second average (Measured using a 30 second interval), then if the 60 sec average is approaching 50% of the TPS license, I'd expect to start seeing TPS transactions being dropped.
