28 INSTALLATION INSTRUCTIONS:
30 - Download, compile and install liburcu.
31 - In this package's tree, run ./configure.
35 - See the manual for usage instructions.
37 If compiling from the git repository, run ./bootstrap before running
38 the configure script, to generate it.
43 LTTV is used for viewing UST traces. LTTV may be obtained at
44 http://lttng.org in the Downloads section.
46 This release has been tested with LTTV 0.12.32.
51 This package contains the following elements.
54 The actual userspace tracing library that must be linked to the
55 instrumented programs.
58 A program to control the tracing of userspace applications. It can list
59 markers, start the tracing, stop the tracing, enable/disable markers, etc.
62 The public header files that will be installed on the system.
65 The daemon that collects trace data and writes it to the disk.
74 An example library that can be LD_PRELOAD'ed to instrument calls to malloc()
75 in any program without need to recompile it.
78 A library that is LD_PRELOAD'ed, and that hijacks calls to several system
79 calls in order to trace across these calls. It _has_ to be LD_PRELOAD'ed
80 in order to hijack calls. In contrast, libust may be linked at build time.
83 A library to control tracing in other processes. Used by ustctl.
86 A static library shared between libust, ust-consumerd and libustctl, that
87 provides functions that allow these components to communicate together.
90 A library to create ust consumers by registering callbacks, used by
94 An asynchronous signal-safe version of snprintf.
97 A simple library that uses JNI to allow tracing in java programs.
