MSRTARG keyword

Use the MSRTARG keyword to specify how often a response time exception must occur. Exception level monitoring begins when an exception occurs in a discrete sample of 100 consecutive I/O transactions for a device. Valid range is 1 to 99 and the default value, if not specified, is 51.

Tip: To find out how you configure devices to collect I/O data when exceptions occur, see the MSR subkeyword section in Device selection keywords.
