Persistent column order in Events Table for user preferred column order

It is possible to reorder the columns of the Events Table and the order is persisted so that after closing and opening of a trace with the same trace type the same column order is used.

New columns in LTTng Kernel events table

The Events Table of LTTng Kernel traces has been extended to display the thread ID (TID) and priority (Prio) of current running process. These values are deduced using the LTTng Kernel state system.

Control flow view filtering enhancement

The filter feature of the Control Flow view has been enhanced to allow selection of active threads or deselection of inactive threads.

Enhancement of time range selection

It is now possible to expand the selected time range using keyboard or toolbar actions in time graph views (e.g. Control Flow view). This allows the user to select exact time ranges spanning from one event to another event.

Performance Improvements

Several performance improvements have been made to the Common Trace Format (CTF) parser and for building of any state system, for example the LTTng Kernel state system used for the Control Flow view and Resources view (see [2]).

Cropping of CTF Traces

A Common Trace Format (CTF) writer has been introduced to be able to crop a CTF trace to a given time range. Using this feature it is possible to crop a large CTF trace into a smaller trace which will speed up the analysis. Please note that there is no UI support available yet. This will be added in the upcoming releases.

TMF remote feature

TMF remote API

The purpose of the TMF remote API is to provide a programming interface to the PTP remote services implementation for connection handling, command-line executions and file transfer handling. It provides utility functions to simplify repetitive tasks.

Refer to chapter Remote API of the Developer Guide for detailed information about the feature.

Remote fetching of traces

It is possible to import traces automatically from one or more remote hosts according to a predefined remote profile by using the Fetch Remote Traces wizard.

Refer to chapter Remote Fetching of the User Guide for detailed information about the feature.

API Breakage

The API has been modified to streamline the generic interfaces and provide new capabilities. Developers that have been extending the functionality prior Trace Compass 1.0 will have to adjust their code base to these changes.

Upgrade Support

Please note that it is not possible to update the Trace Compass 0.1.0 application on Mac OS to Trace Compass 1.0.0 because of a change in how Eclipse applications are distributed in Eclipse 4.5, see bug 431116. Upgrading from 0.1.0 to 1.0.0 is supported on other platforms.
