MSR subkeyword

You can use the MSR optional subkeyword to specify that device I/O is to be collected on an exception basis.

Data is not collected for the device until the response time for the device crosses the threshold a specified number of times. The keyword MSRTARG is used to control the number of times an exception must occur before monitoring takes place. You can use the MSR optional subkeyword with all device keywords including the ALL keyword.

Tip: To find out how to set the threshold for exceptions, see the MSRTARG keyword section in Device monitoring option keywords.
