What is Trace Compass?

Eclipse Trace Compass is an open source application to solve performance and reliability issues by reading and analyzing traces and logs of a system. Its goal is to provide views, graphs, metrics, and more to help extract useful information from traces, in a way that is more user-friendly and informative than huge text dumps.

Important features of Trace Compass:

1.) 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.

2.) KERNEL ANALYSIS: Displays the states of processes and resources over time, using information from Linux kernel traces.

3.) 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.

4.) 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.

Benefits of Trace Compass:

1.) Reduce time to identify faults

2.) Observe multi-core, heterogeneous, virtualized, and distributed systems

3.) Use the same analysis tool for development, testing, and production

4.) Extend the framework to fit the needs of your organization

5.) Avoid vendor lock-in by using an open source solution
