Understanding your application's I/O behavior
and presentation of Linux metrics important in the analysis
of application I/O performance and behavior.
Collect
iot
A Linux command that enables collection of I/O instrumentation data on all programs downstream of the iot command.
Monitor
Instrumentation Streams
