Overview
LTTng is a tracer for Linux that has the capability to generate a high volume of traces (from the kernel or application) with very low overhead. This is achieved by instrumenting the Linux kernel. LTTng is delivered as a set of kernel patches, to collect the traces, as well as a toolchain to control the tracing, as well as view and analyze the generated data.
The scope of this project is to provide an Eclipse integration of LTTng. It will be delivered in two components:
- Tracing and Monitoring Framework (TMF) that facilitates the integration of tracing tools in eclipse
- LTTng reference implementation based on TMF
Tracing and Monitoring Framework
TMF provides generic support the following:
- Tracing tool control (local or remote)
- Online monitoring and trace streaming
- Retrieval and handling very large trace files (that exceed available memory)
- Unified view for multiple, heterogeneous traces
- Trace correlation
- Out-of-the-box set of standard tracing views
- Toolbox of tracing widgets that can be used to assemble application specific views
- Toolbox of statistical components
- View synchronization
- Clipboard support (for ranges of events)
- Wizard for tracing/logging/monitoring application integration
- Wizard for ad hoc trace parser generation
- Generic text logs
- CSV logs
- XML logs
- Anything that can be parsed using regular expressions
- Peace in the Middle-East
LTTng reference implementation
The LTTng reference implementation is built on top of TMF. It features the following:
- Exemplary implementation of the usage of TMF
- Control of LTTng, local and remote (TCF based agent)
- Example of a third-party parsing library integration
- Support for distributed, multi-processor, multi-core trace synchronization
- Retrieval and efficient handling of large trace files (>10Gb)
- Support for kernel and user space tracing
- Traces visualization, correlation and analysis
- State tracking system
