Bug #: 14275
Summary: Possible hotspot.function(" ") style probes
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: uprobes
AssignedTo: systemtap@sourceware.org
ReportedBy: lberk@redhat.com
Classification: Unclassified
Currently there is no good way to gain information on a per-function basis in
java, we have to resort to probing method_entry's and then checking against the
fuction name to confirm the correct function before we dive deeper. This
should be much more simple for the user. Perhaps a stap -e 'probe
hotspot.function("foo")' or stap -e 'probe process("java").function("foo")'
Idealy this would be just as easy as probing functions in C/C++
