NAME

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

DESCRIPTION

       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 older version) that has neither utrace func‐
       tionality nor an acceptable substitute.

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

RESOLVING THE ISSUE

       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.
