Trace Compass

Screenshots

Call Stack

If you can define trace events representing function entries and exits, you can display the call stack of your application over time. You can also get profiling information from the Flame Graph or descriptive statistics.

Kernel Analysis

Displays the states of processes and resources over time, using information from Linux kernel traces.

UST Memory

Using LTTng-UST's C standard library wrapper, all calls to memory allocation and free are traced. You can display the memory utilization or find potential memory leaks.

Extend Trace Types

The base framework can be extended to add support for new trace types. Support for libpcap traces (the format used by Wireshark) was added this way.

Key Features

Offline analysis of complex issues

Real-time deadline investigation
Latency analysis
Log correlation with operating system traces
Network packet correlation across layers
Identification of relevant information in large amounts of trace data
Critical path analysis
Causes of high processor usage and memory leaks
Correlation of hardware and software components execution traces
Time synchronization of traces from different nodes
Symbol name resolution using debug information
Additional analyses available with the Trace Compass Incubator
and more!

Multiple trace formats supported

Common Trace Format (CTF), including but not limited to:
- Linux LTTng kernel traces
- Linux LTTng-UST userspace traces
- Linux Perf traces converted to CTF
- Bare metal traces
- Integration with the LTTng-Analyses scripts
Hardware traces (e.g. IEEE Nexus 5001 CTF conversion). See also this link.
GDB traces for debugging
The Best Trace Format (BTF) for OSEK
The libpcap (Packet CAPture) format, for network traces
Custom text or XML parsers that can be added right from the graphical interface by the user
Can be extended to support various log or trace files.
Provided by the TraceCompass Incubator:
- Linux FTrace raw textual format
- Google's trace event json format
- Additional Linux Perf2ctf traces features
- Android traces
- UFtrace format

For more information, see the Trace Compass datasheet.

Benefits
