bpftrace adds statement probes by source location

Introduced 2026-05-26 · score 0.95

HOW TO USE IT

When the target has DWARF source-location information, trace a valid statement from the specified file with a source-location uprobe; use the optional column to narrow the location.

bpftrace -e 'uprobe:<binary>@<file>:<line> { printf("hit\n"); }'

WHY THIS HELPS

Trace a particular source statement while debugging a program.

REQUIREMENTS AND LIMITATIONS

  • Version: v0.26.0
  • <binary> (required): ELF binary to probe.
  • <file> (required): Absolute or relative source-file path.
  • <line> (required): Line number that must refer to a valid statement in the file.
  • <column>: Optional column in the source location; if supplied, it must refer to a valid statement.
  • { ... } (required): Probe action block; runs when the probe fires.
  • Prerequisite: The target needs DWARF source-location information for statement probes.
  • Prerequisite: The binary path must identify a valid ELF target; only statements originating in the specified file are considered, so statements from included files are ignored.
