1 | = Overview = |
| 2 | The Linux Tools Trace Viewer is a stand-alone application based on Eclipse's | |
| 3 | Rich Client Platform (RCP). The purpose of this is to provide a lightweight | |
| 4 | application to view and analyze traces. It includes all TMF (Tracing and | |
| 5 | Monitoring Framework) features, as well as all features from the LTTng (Linux | |
| 6 | Tracing Toolkit next generation) Eclipse integration, which are provided by the | |
| 7 | Linux Tools Project. | |
| 8 | ||
| 9 | = Getting Started = | |
| 10 | To start the Linux Tools Trace Viewer, go to the directory where the Trace | |
| 11 | Viewer is installed and then run the application named '''traceViewer'''. | |
| 12 | During startup, the Trace Viewer will create, if necessary, an Eclipse workspace | |
| 13 | in the user's home directory with the name ''.traceviewer''. It also creates, if | |
| 14 | needed, a default tracing project called ''Tracing''. | |
| 15 | ||
| 16 | Now the application can be used as described in the User Guide for Linux Tools | |
| 17 | LTTng integration (see section [[#References | References]]). | |

20 | To open a trace, click on the '''File''' menu and select '''Open Trace...'''. |
| 21 | A new dialog will show for selecting a trace to open. Select a trace file | |
| 22 | and then click on '''OK'''. Note that for traces that are directories | |
| 23 | (such as Common Trace Format (CTF) traces) any file in the trace directory can | |
| 24 | be selected to open the trace. Now, the trace viewer's auto detection algorithm | |
| 25 | will validate the trace against all known trace types. If multiple trace types | |
| d3e89107 BH |
26 | are valid, a trace type is chosen based on a confidence criteria. The |
| 27 | validation process and the computation of the confidence level are trace type | |
| 28 | specific. After successful validation the trace will be opened with the | |
| 29 | detected trace type. | |
| 30 | ||
| 31 | Alternatively the user can launch the trace viewer with the command-line | |
| 32 | argument '''--open <trace-path>'''. The trace will then automatically open | |
| 33 | using the same algorithm than described above. | |

| 35 | In both of the above cases, the trace will be linked to the default project. | |
