Issue/Introduction
When the proper options are coded in the RUNSYSIN member, there are five types of messages written to the activity log.
These message types are explained as follows:
This will generate the following types of messages every minute:
Message ID ...+ N00M10
Message Text
hh:mm:ss ET: ss.th DC: s.tttttt TC: s.tttttt %A: pp.th
Message Explanation
This message is issued to the log every minute or every 15 seconds (depending on whether CPUCM or CPUFM is specified in the JCL parm XOPT list), if the XOPT JCL parameter CPUMM is specified. It provides an indication of the region CPU utilization in the preceding period.The fields are as follows:
hh:mm:ss displays the time the message was issued.
ET: ss.th displays the interval elapsed time. This is normally 60.00 or 15.00. If significantly longer, it may indicate that the region is not being dispatched in a timely manner due to system load.
DC: s.tttttt displays the amount of CPU time used in this period by the CA NetMaster Maintask (Delta CPU).
TC: s.tttttt displays the total amount of CPU %A: pp.th displays the average percentage of the time that the CA NetMaster Maintask was active in this period (that is, (delta CPU times 100) divided by elapsed time). Time used by the CA NetMaster Maintask since this region started.
Message ID ...+ N00M11
Message Text
hh:mm:ss ET: ss.th TCB: DC: s.tttttt TC: s.tttttt %T: pp.th
Message Explanation
This message is issued to the log every minute or every 15 seconds (depending on whether CPUCM or CPUFM is specified in the JCL parm XOPT list), if the XOPT JCL parameter CPUMM is specified. It provides a breakdown of the 'maintask' CPU utilization in the preceding period.This message is produced only if XM=ZIIP or XM=BEST is specified in the JCL parms. IT indicates the CPU time used by the maintask TCB in the preceding period.
The fields are as follows:
hh:mm:ss displays the time the message was issued.ET: ss.th displays the interval elapsed time. This is normally 60.00 or 15.00. If significantly longer, it may indicate that the region is not being dispatched in a timely manner due to system load.
TCB: indicates that the times in this message pertain to the maintask
TCB CPU utilisation.DC: s.tttttt displays the amount of CPU time used in this period by the CA NetMaster Maintask (Delta CPU).
TC: s.tttttt displays the total amount of CPU time used by the CA NetMaster Maintask since this region started.
%T: pp.th displays the percentage of the CPU time expended in the period by the TCB, the percentage being of the total of TCB times (as in this message), and SRB times (as in the following N00M12 message).
Message ID ...+ N00M12
Message Text
hh:mm:ss ET: ss.th SRB: DC: s.tttttt TC: s.tttttt %S: pp.th
Message Explanation
This message is issued to the log every minute or every 15 seconds (depending on whether CPUCM or CPUFM is specified in the JCL parm XOPT list), if the XOPT JCL parameter CPUMM is specified. It provides a breakdown of the 'maintask' CPU utilization in the preceding period.This message is produced only if XM=ZIIP or XM=BEST is specified in the JCL parms. IT indicates the CPU time used by the paired maintask SRB in the preceding period.
The fields are as follows:
hh:mm:ss displays the time the message was issued.
ET: ss.th displays the interval elapsed time. This is normally 60.00 or 15.00. If significantly longer, it may indicate that the region is not being dispatched in a timely manner due to system load.
SRB: indicates that the times in this message pertain to the SRB associated with the maintask TCB.
DC: s.tttttt displays the amount of CPU time used in this period by the SRB (Delta CPU).
TC: s.tttttt displays the total amount of CPU time used by the SRB since the region started.
%S: pp.th displays the percentage of the CPU time expended in the period by the SRB, the percentage being of the total of TCB times (as in the preceding N00M11 message), and SRB times (as in this message).
Message ID ...+ N00M13
Message Text
hh:mm:ss ET: ss.th MS: sss #W: www #T: ttt XM: mmmm
Message Explanation
This message is issued to the log every minute or every 15 seconds (depending on whether CPUCM or CPUFM is specified in the JCL parm XOPT list), if the XOPT JCL parameter CPUMM is specified. It provides information about events during the preceding period.This message is produced only if XM=ZIIP or XM=BEST is specified in the JCL parms.
The fields are as follows:
hh:mm:ss displays the time the message was issued.
ET: ss.th displays the interval elapsed time. This is normally 60.00 or 15.00. If significantly longer, it may indicate that the region is not being dispatched in a timely manner due to system load.
MS: sss displays the number of 'mode switches' between TCB and SRB mode.
#W: www displays the number of real waits issued in this period.
#T: ttt displays the number of timer requests issued in this period.
XM: mmm displays the execution mode, normally ZIIP.

Message Text
hh:mm:ss ET: ss.th PH: s.tttttt ZC: s.tttttt ZZ: s.tttttt %Z: p.th
Message Explanation
This message is issued to the log every minute or every 15 seconds (depending on whether CPUCM or CPUFM is specified in the JCL parm XOPT list), if the XOPT JCL parameter CPUMM is specified. It provides information about events during the preceding period.This message is produced only if XM=ZIIP or XM=BEST is specified in the JCL parms.
The fields are as follows:
hh:mm:ss displays the time the message was issued.
ET: ss.th displays the interval elapsed time. This is normally 60.00 or 15.00. If significantly longer, it may indicate that the region is not being dispatched in a timely manner due to system load.
PH: s.tttttt displays the delta of the ASSBPHTM field, indicating the total pre-emptable SRB CPU time expended in the period.
ZC: s.tttttt displays the delta of the ASSB_TIME_zIIP_ON_CP field, indicating the total zIIP-eligible CPU time expended on normal CPs during the period.
ZZ: s.tttttt displays the delta of the ASSB_TIME_ON_zIIP field, indicating the total zIIP-eligible CPU time expended on zIIPs during the period.
%Z: p.th indicates the percentage of total zIIP-eligible time that was actually expended on a zIIP.
