Clock-based Profiling Under the Linux OS

Under the Linux OS, the only metric available is User CPU time. Although the total CPU utilization time reported is accurate, it may not be possible for the Analyzer to determine the proportion of the time that is actually System CPU time as accurately as for the Solaris OS. Although the Analyzer displays the information as if the data were for a lightweight process (LWP), in reality there are no LWP’s on a Linux OS; the displayed LWP ID is actually the thread ID.
