LTTng Tracer Control | References |
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.
Performance
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.
Tracer control limitations (for LTTng Tracer Toolchain v0.x)
Due to errors in the LTTng remote agent, controlling of user space traces is currently not possible.
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.
For kernel traces, it's currently not possible to configure the channels. This will be added in the next release.
64-bits and non-x86 host architectures
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.
