Consider the following:
Each CICS data collector writes a CICS Transaction Summary record for each unique transaction ID that executed during the system data collection interval.
If the data from multiple CICS regions get logged to the log stream, then this value must be the combined total for those CICS regions.
On average we are assuming that 100 unique transaction IDs execute during each interval.
It also assumes that 10 CICS regions are being logged to the log stream.
Hourly count = 100 * 4 * 10
The large amount of data can be maintained.
