32 | <h1 id="Limitations">Limitations</h1> | |
33 | <p>The current implementation is under heavy development and some important features are still missing. Here is a list of the known bugs and missing features that are being worked on.</p> | |
34 | <p> | |
35 | <b>Performance</b> | |
36 | </p> | |
12bf6834 | 37 | <p>The current version takes 3-5 more time to fully parse a trace than the finely optimized C version (LTTv). However, once a trace/experiment is selected, the user has immediate feedback and can start navigating and visualizing the trace while the parsing takes place in the background.</p> |

12bf6834 | 39 | <b>Tracer control limitations</b> |
70f06a6f | 40 | </p> |
12bf6834 FC |
41 | <p>Due to errors in the LTTng remote agent, controlling of user space traces is currently not possible.</p> |
42 | <p>The LTTng agent doesn't allow to retrieve the trace state, i.e. whether a trace is started or stopped. Therefore, when reconnecting with Eclipse, the LTTng control is not able to display the correct state. Currently, the trace is considered as started.</p> | |
43 | <p>For kernel traces, it's currently not possible to configure the channels. This will be added in the next release. </p> | |

44 | <p> |
45 | <b>64-bits and non-x86 host architectures</b> | |
46 | </p> | |
47 | <p>The parser libraries have not been extensively tested for 64-bits and not tested at all on non-x86 architectures. The code is believed to work on a broad range of architectures but this cannot be certified for now.</p> | |
48 | <p> | |
49 | <b>Searches and Filters</b> | |
50 | </p> | |
51 | <p>There is currently no way to filter events following some criteria or to dynamically sort the different fields.</p><hr/> | |
