GitHub - yoshinorim/quickstack: A tool to take call stack traces with minimal overheads
quickstack is a tool to take call stack traces with minimal overheads. There are a couple of tools to take stack traces such as gdb, pstack, but these tools have serious overheads. In many cases, target process stops for 0.2-N seconds. So it is dangerous to use such tools in production environment. quickstack makes it possible to take stack traces in less than 1 milliseconds. This is much smaller

[Announce] 'perf sched': Utility to capture, measure and analyze scheduler latencies and behavior
[Announce] 'perf sched': Utility to capture, measure and analyze scheduler latencies and behavior The recent discussions on lkml about scheduler interactivity have again demonstrated a particular weakness in Linux instrumentation: the lack of a turn-key solution that gives us both high level summaries and fine low level details about CPU scheduler behavior. This makes it needlessly hard to talk ab
Reducing latency spikes by tuning the CPU scheduler
In this post we will walk through an investigation of latency spikes observed in the ScyllaDB 1.0.x version family, which are linked to the scylla-jmx service running alongside the ScyllaDB server on the same system. We will show how the scheduler can be tuned to reduce latency spikes. ScyllaDB 1.2, which is at the release candidate stage this week, will have all relevant fixes. Users of that vers
Autopilot Pattern Applications
The autopilot pattern automates in code the repetitive and boring operational tasks of an application, including startup, shutdown, scaling, and recovery from anticipated failure conditions for reliability, ease of use, and improved productivity. Why do we need to do this? Who is this for? How do we do it? How does this differ from previous approaches to automation? How does this differ from sched
