Co-evolving Tracing and Fault Injection with Box of Pain
Distributed systems are hard to reason about largely because of uncertainty about what may go wrong in a particular execution, and about whether the system will mitigate those faults. Tools that perturb executions can help test whether a system is robust to faults, while tools that observe executions can help better understand their system-wide effects. We present Box of Pain, a tracer and fault injector for unmodified distributed systems that addresses both concerns by interposing at the system call level and dynamically reconstructing the partial order of communication events based on causal relationships. Box of Pain’s lightweight approach to tracing and focus on simulating the effects of partial failures on communication rather than the failures themselves sets it apart from other tracing and fault injection systems. We present evidence of the promise of Box of Pain and its approach to lightweight observation and perturbation of distributed systems.

Ten Platform Commandments
Your observability must center your users’ perspective, not your own. The health of the system doesn’t matter. The health of every request, and every high-cardinality grouping of requests — those are what matter

libstapsdt
libstapsdt is a library which allows creating and firing Systemtap's USDT probes at runtime. It's inspired on chrisa/libusdt. The goal of this library is to add USDT probes functionality to dynamic languages.

Linux Load Averages: Solving the Mystery
When Linux load averages increase, you know you have higher demand for resources (CPUs, disks, and some locks), but you aren't sure which. You can use other metrics for clarification

ktap
ktap is a new script-based dynamic tracing tool for Linux, it uses a scripting language and lets users trace the Linux kernel dynamically. ktap is designed to give operational insights with interoperability that allows users to tune, troubleshoot and extend kernel and application. It's similar with Linux Systemtap and Solaris Dtrace

LTTng Project
The LTTng project aims at providing highly efficient tracing tools for Linux. Its tracers help tracking down performance issues and debugging problems involving multiple concurrent processes and threads. Tracing across multiple systems is also possible.

Apart from LTTng's kernel tracer and userspace tracer, viewing and analysis tools are part of the project. The LTTV viewer permits to analyze and show traces, both in text format and graphically.
