| | 55 | PACKAGE CONTENTS: |
| | 56 | |
| | 57 | This package contains the following elements. |
| | 58 | |
| | 59 | - libust |
| | 60 | The actual userspace tracing library that must be linked to the |
| | 61 | instrumented programs. |
| | 62 | |
| | 63 | - ustctl |
| | 64 | A program to control the tracing of userspace applications. It can list |
| | 65 | markers, start the tracing, stop the tracing, enable/disable markers, etc. |
| | 66 | |
| | 67 | - include |
| | 68 | The public header files that will be installed on the system. |
| | 69 | |
| | 70 | - ust-consumerd |
| | 71 | The daemon that collects trace data and writes it to the disk. |
| | 72 | |
| | 73 | - doc |
| | 74 | The documentation. |
| | 75 | |
| | 76 | - tests |
| | 77 | Various test programs |
| | 78 | |
| | 79 | - libustinstr-malloc |
| | 80 | An example library that can be LD_PRELOAD'ed to instrument calls to malloc() |
| | 81 | in any program without need to recompile it. |
| | 82 | |
| | 83 | - libustfork |
| | 84 | A library that is LD_PRELOAD'ed, and that hijacks calls to several system |
| | 85 | calls in order to trace across these calls. It _has_ to be LD_PRELOAD'ed |
| | 86 | in order to hijack calls. In contrast, libust may be linked at build time. |
| | 87 | |
| | 88 | - libustctl |
| | 89 | A library to control tracing in other processes. Used by ustctl. |
| | 90 | |
| | 91 | - libustcomm |
| | 92 | A static library shared between libust, ust-consumerd and libustctl, that |
| | 93 | provides functions that allow these components to communicate together. |
| | 94 | |
| | 95 | - libustconsumer |
| | 96 | A library to create ust consumers by registering callbacks, used by |
| | 97 | ust-consumerd. |
| | 98 | |
| | 99 | - snprintf |
| | 100 | An asynchronous signal-safe version of snprintf. |
| | 101 | |
| | 102 | - java |
| | 103 | A simple library that uses JNI to allow tracing in java programs. |
