Operating system overview

A new perspective with a set of predefined views is available showing CPU Usage, Disk I/O Activity and Kernel Memory Usage populated with from LTTng Kernel traces.

LTTng Control view enhancements

Enabling all kernel tracepoints and syscall at once

It is now possible to enable all LTTng kernel tracepoints and syscall at the same time.

Enabling LTTng Kernel events by name

It is now possible to enable LTTng Kernel events by specifying one or more names. This is useful when tracing Kernel modules that are loaded manually.

Control Flow view enhancements

Following events per TID

Two navigation buttons have been added to the toolbar of the Control Flow view to follow events for the selected thread. With this is possible to go to the next or previous event from the current time for the selected thread.

Custom Text/XML parser enhancements

Support for event types in custom parsers

It is now possible to assign an event type in custom text and XML parser wizard.

The event type will be displayed in Event type column. Data-driven analysis can take advantage of the event type definition.

Latency analysis enhancements

Total latency statistics

The Latency statistics view now will display the sum of a latencies per type in the Totals column. This is applicable to the Latency statistics view created by the data-driven pattern analysis or in Java like the System Call analysis.

Other enhancements

Open XML Editor for data-driven analysis

It is now possible to edit data-driven analyses directly within Trace Compass using the "Edit..." of the XML analysis manager.

This will open a XML editor provided by the Eclipse WST project. TraceCompassXMLEditor.png

Progress bar for indexing of CTF traces

The progressing of the trace indexing of CTF traces will be shown in the Progress view as well as the status bar of Trace Compass.
