WARNING::PROCESS-TRACKING(7stap)        WARNING::PROCESS-TRACKING(7stap)

NAME         top

       warning::process-tracking - process-tracking facilities are not
       available

DESCRIPTION         top

       These errors and warnings occur when the kernel systemtap is
       running on lacks support for user-space process tracking
       facilities.

   COMPILE-TIME ERROR
       The error

              ERROR: user-space process-tracking facilities not available

       occurs when the script contains a uprobes probe point that the
       current kernel does not support.

   RUNTIME WARNINGS
       The warning,

              WARNING: process-tracking facilities are not available in this kernel

       and the related message,

              WARNING: cannot track target in process '...'

       both occur at runtime when running on a kernel (generally an old‐
       er version) that has neither utrace functionality nor an accept‐
       able substitute.

       The script should still load and run. However, probes that rely
       on availability of process-tracking facilities will silently fail
       to trigger.

RESOLVING THE ISSUE         top

       If process-tracking functionality is absolutely necessary, either
       a kernel version newer than 3.5 is needed, or an older version
       must be compiled with appropriate utrace patches.
