CA APM CE (CEM) reports are based on aggregated statistics of your business transactions.
CA CEM allows you to specify the report view time frame in various ways:
When someone generates a report for "Previous Month", does that mean that it will pull the previous calendar month's report or the past 30 days report?
CA APM 9.x , CA APM 10.x
Here are the Default Time Frames
Daily: Today, Yesterday
Weekly: Current Week, Previous Week
Monthly: Current Month, Previous Month
Yearly: Current Year, Previous Year
Here are the Custom Time Frames
Custom Day: Any day in the last 30 days
Custom Week: Any week in the last year
Custom Month: Any month in the last two years
So selecting the Previous Month and Last 30 days will produce different results.
"Previous Month" is based on the calendar month vs. "Past 30 days"
