This guide shares practical embedded‑development hacks—from diplomatically blaming hardware issues and using the Linux devmem tool to read registers, to modular sensor driver design, safe pointer practices, and dynamic log‑level control—helping engineers reduce overtime and improve code maintainability.
This guide explains how to use Alibaba Cloud's log governance feature to dynamically collect stack traces, method parameters, and other runtime information at arbitrary points in a Java application without restarting, and how to forward those logs to SLS Logtail for further analysis.
This article explains how to use a non‑intrusive microservice insight capability to dynamically log and observe Ribbon load‑balancing internals, capture service discovery data, and troubleshoot full‑link gray‑release traffic issues in Spring Cloud environments.
During a high‑traffic promotion a service ran out of disk space because massive log files weren't cleaned, the investigation revealed a lingering SLS process holding deleted files, and the article walks through the root‑cause analysis, the kill‑process fix, and a Spring‑Boot starter that dynamically degrades log levels to prevent recurrence.
Holmes is a zero‑cost dynamic logging system for Android apps that automatically instruments every method to emit trace logs, stores them locally, and lets developers remotely retrieve precise execution histories and run Lua scripts for on‑device snapshots, dramatically reducing debugging time despite fragmentation and low performance impact.
The article explains the design, implementation, and operational benefits of a middleware component that dynamically adjusts log levels in Java services, helping large‑scale delivery platforms balance comprehensive debugging information with system performance and avoid catastrophic failures during peak traffic.
This guide shows how to enable the Spring Boot 1.5.x /loggers actuator endpoint, configure a simple application, and use POST and GET requests to modify and inspect log levels at runtime without restarting the service.
