ACPU
The Address Space CPU (ACPU) sampler produces a warning message when an address space uses more than a specified percentage of CPU time during the reporting interval and the total CPU utilization has exceeded the specified percentage.
Syntax
The parameters are defined as follows:
Parameter | Description |
|---|---|
int | is the length of the sample period in intervals The default sample period is 30 seconds (one interval). |
name | is the name of the address space to be monitored If the last character of the name is an asterisk (*), the name is to be treated as a generic address-space name prefix; that is, any address space whose name matches the character string up to but not including the asterisk is monitored. To monitor all address spaces, except those in the exclusion list, specify an asterisk (*). |
percent | is the CPU busy percentage for which an address space must be responsible before an exception message is issued for that address space |
type | is the type of address space to be monitored, where
|
minpct | is the percentage of system CPU busy that must be reached before exception messages are issued The default is a system CPU busy percent greater than 0. |
Example
This example uses a reporting interval of 30 seconds. The example control statement issues the PWSACP94 warning message (at two-minute intervals) for each address space that is not in the exception list that had at least a 10% CPU utilization and if the total CPU utilization during the interval was at least 50%.
ACPU 4,*,10,A,50
Warning message
The following warning message is issued by the ACPU sampler:
PWSACP94 *WARNING* CPU usage is percent % for type name
The variables in the message are:
Variable | Description |
|---|---|
percent | is the percentage of cpu time that the address space used |
type | is the type of address space (Job, STC, TSU, or All) |
name | is the name of the address space exceeding the limit |
