WARNING::PROCESS-TRACKING(7stap) WARNING::PROCESS-TRACKING(7stap)
warning::process-tracking - process-tracking facilities are not
available
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 cur‐
rent 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 functionality nor an acceptable sub‐
stitute.
The script should still load and run. However, probes that rely on
availability of process-tracking facilities will silently fail to
trigger.
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.
