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 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.
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.
