AIOR
The Address Space I/O Rate (AIOR) sampler produces a warning message when an address space issues EXCPs at a rate that exceeds the defined threshold during a reporting interval.
Syntax
The parameters are defined as follows:
Parameter | Description |
|---|---|
int | is the length of the sample period in intervals |
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. |
rate | is the rate of EXCPs-per-second that must be reached before exception messages are issued The default is an I/O rate greater than 25 EXCPs per second. |
type | is the type of address space to be monitored, where
|
Example
Assuming a report interval of 30 seconds, the following control statement displays warning messages at two-minute intervals for each address space whose I/O rate exceeds 25 EXCPs-per-second over the preceding two minutes:
AIOR 4,*,25,A
Warning message
The following warning message is issued by the AIOR sampler:
PWSAIR91 *WARNING* I/O RATE FOR ttt nnnnnnnn IS excp EXCPs/SEC
Message PWSAIR01 indicates that the specified address space has exceeded the warning threshold for I/O rate, where
Variable | Description |
|---|---|
ttt | is STC, TSU, or JOB |
nnnnnnnn | is the address space name |
excp | is the EXCPs issued by the address space during the interval |
