Hi Clint, I am quite new to this interesting tool and trying to use it to check if there is any memory leak in our software client and after applying the patch whether the memory leaks have been removed a bit.
I have collected the data for two days, each for before and after applying the patch. Currently there is no alert in the report. And how can I interpret the information in the report, especially what does "Hourly Trend" mean?

Thank you very much!

PAL time slices the counter log into equal sized time ranges. All counter values collected in each time slice is averaged. For each time slice, PAL compares the average value of the time slice to all average values from the previous time slices to produce
an increasing or decreasing trend. Finally, I convert it to an hourly trend. So, each time slice has an hourly trend which is based on that time slice and all previous time slices. The Hourly Trend in the overall stats is the the hourly trend of the entire
The stats above show me that you have an increasing hourly trend of 584KB and 1,059KB the entire time range of the counter log. If this is over a long period of time, then it means that your second Client app is progressively leaking 1MB per hour. This is
a common result because applications will typically use more memory as they are being used.
