BCPU
The message can be suppressed if a given threshold for total CPU usage is not reached during the reporting interval.
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) |
percent | is the percentage of total system CPU time that a batch address space must be responsible for before an exception message is issued for that address space |
rptno | is the maximum number of address spaces to be listed whenever a CPU overload condition is detected; the default is 5 |
minpct | is the CPU busy percentage that must be reached before exception messages are issued; the default is a system CPU busy percentage greater than zero |
Example
Assuming a report interval of 30 seconds, the following control statement displays up to five warning messages at two-minute intervals if the system-CPU busy percentage exceeds 50 percent over the preceding two minutes:
BCPU 4,35,5,5
A warning is issued for any batch address space that has been active 35 percent of the total CPU busy time.
Warning message
The following warning message is issued by the BCPU sampler:
PWSBCPU1 *WARNING* CPU USAGE IS ppp% FOR JOB jjjjjjjj
Message PWSBCPU1 indicates that the specified address space has exceeded the warning threshold for percentage of system-CPU busy time, where
Variable | Description |
|---|---|
ppp | is the address space busy percentage |
jjjjjjjj | is the address space name |
