The percentage of CSA usage below 16 megabytes. The TCP/IP address space uses a nominal amount of CSA below the 16MB line. Determine a conditional value by observing history to obtain a working baseline. A percentage of CSA much higher than the established baseline indicates an increase in workload and might signify an impending performance problem.
Use the diagnostic procedures outlined in the IBM(R) z/OS(R) Communications Server: IP Diagnosis Guide to take corrective action.
Formula: CSA Percent Below 16MB >= 5
