Set the depth for the backtraces collected for OS runtime libraries calls.
Set the stack dump size, in bytes, to generate backtraces for OS runtime libraries calls.
Set the duration, in nanoseconds, that all OS runtime libraries calls must execute before backtraces are collected.
< nanoseconds >
Set the duration, in nanoseconds, that Operating System Runtime (osrt) APIs must execute before they are traced. Values much less than 1000 may cause significant overhead and result in extremely large result files. Default is 1000 (1 microsecond). Note: Not available for IBM Power targets.
All of these are modifiers to the osrt option itself.
