Revision as of 10:05, 27 January 2015

This page is meant to track all the higher-level planned features and feature requests. As features get implemented, we could move them to "Targeted for version x.y" and "Delivered in version x.y" sections. It would always track the "current" roadmap, but over time would also become a history of which feature was delivered in which version.

On track for 1.0.0

• Support for perf traces in CTF format

Planned

These features have people currently working on them, but no set release date yet.

• Dependency analysis framework (example)
• Configurable event table columns
• Virtual Machine analysis (See screenshots at the end of this presentation)
• Describe data-driven filters and high-level states
• Visually define data-driven analysis with state diagrams
• Support for remote fetching of traces using remote profiles
• Support for new features of recent versions of LTTng Tools in LTTng Tracer Control view
  • Remaining features of LTTng Tools v2.5
  • MI support for LTTng Tools v2.6 has been already merged. Remaining features of LTTng v2.5 and v2.6 need to be added to the MI support of the Tracer Control view.
• Aligned x-Axis (time)
• Latency Analysis

Wishlist

These features have been proposed and deemed interesting to have, but nobody has committed to work on them yet.

• Support for perf traces in standard perf.data

• Support for ftrace traces
  • Documentation at https://www.kernel.org/doc/Documentation/trace/ftrace.txt
  • Investigate if we could re-implement the KernelShark view using a generic time graph view

• Reduce the size of state system history files
  • Timestamps (2x 64 bits) are repeated for every single interval. Low-hanging fruit (using protocol buffers?)
  • Compress often-used values (including strings).

• Support for data-driven Sequence Diagrams

• Sequence Diagrams for PCAP traces

• Python support for Trace Compass
