The lttng-tools project provides a session daemon lttng-sessiond that acts as a tracing registry, the lttng command line for tracing control, a lttng-ctl library for tracing control and a lttng-relayd for network streaming.

While the CTF reading libraries focus on decoding and providing completed and ordered event record objects, the yactfr API offers a lower level of CTF processing. Allowing iteration over individual element sequences to obtain elements: beginning/end of packet, beginning/end of event record, beggining/end of structure, individual data stream scalar values like fixed-length integers, fixed-length floating point numbers, and null-terminated strings, specific clock value update, known data stream ID, and the rest.

Perf-tools is a collection of scripts for performance analysis and instrumentation based on Linux perf_events (aka perf) and ftrace.

Dyninst is a collection of libraries for instrumenting, analyzing and editing binaries. It can attach to an existing program or create a new one out of an ELF file for analysis or modification. It come with a handful of C++ libraries.

SystemTap provides infrastructure to simplify the gathering of information about the running Linux system. This assists diagnosis of a performance or functional problem. SystemTap eliminates the need for the developer to go through the tedious and disruptive instrument, recompile, install, and reboot sequence that may be otherwise required to collect data.

SystemTap provides a simple command line interface and scripting language for writing instrumentation for a live running kernel plus user-space applications. We are publishing samples, as well as enlarging the internal "tapset" script library to aid reuse and abstraction. SystemTap is a tool for complex tasks that may require live analysis, programmable on-line response, and whole-system symbolic access, and can also handle simple tracing jobs.

LTTng kernel modules are Linux kernel modules which make LTTng kernel tracing possible. They include essential control modules and many probes which instrument numerous interesting parts of Linux.

libpatch is a lightweight C library that can be used by tracers, debuggers and other tools for insertion of probes in a program at runtime. It has many strategies to minimize probe overhead and maximize possible coverage.

This package provides facilities for the Publish/Subscribe pattern of message propagation, also known as overlay multicast. The implementation provides topic-based pubsub, with pluggable routing algorithms.

This package provides a collection of helper types for composing different types of routers.

This package implements an object that implements the exchange interface but returns nil values to every request.

This package implements a Badger v4 (a key-value database) backed datastore for IPFS.

Datastore is a generic layer of abstraction for data store and database access. It is a simple API with the aim to enable application development in a datastore-agnostic way, allowing datastores to be swapped seamlessly without changing application code. Thus, one can leverage different datastores with different strengths without committing the application to one datastore throughout its lifetime.

This package profides a test utility code used across many different IPFS related projects.

This is an implementation of the IPLD @urlhttps://ipld.io/specs/codecs/dag-jose/spec/,dag-jose codec.

This package provides a DS implementation backed by Badger.

This package implements the go-datastore interface using a LevelDB backend.

This package provides P2P routing implementations for IPFS development.

Metrics interface for IPFS (Kubo).

Package car allows inspecting and reading CARv2 files, described at https://ipld.io/specs/transport/car.

go-log wraps zap to provide a logging facade. go-log manages logging instances and allows for their levels to be controlled individually.

Package dht implements a distributed hash table that satisfies the IPFS routing interface as specified in kab-dht. This DHT is modeled after Kademlia with S/Kademlia modifications.

IPFS is a global, versioned, peer-to-peer file system. It combines good ideas from Git, BitTorrent, Kademlia, SFS, and the Web. It is like a single bittorrent swarm, exchanging git objects. IPFS provides an interface as simple as the HTTP web, but with permanence built in. You can also mount the world at /ipfs.

This is an implementation of go-datastore that is backed by DynamoDB.

ddbds includes support for optimized prefix queries. When you setup your table's key schema correctly and register it with ddbds, then incoming queries that match the schema will be converted into DynamoDB queries instead of table scans, enabling high performance, ordered, high-cardinality prefix queries.
