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

# [NAME](#NAME)

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

# [DESCRIPTION](#DESCRIPTION)

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

## [COMPILE-TIME ERROR](#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](#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 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](#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.
