Server Monitoring Best Practices: Keeping Your PHP App and MySQL Clusters Alive on Linode

Proactive PHP Application Health Checks Beyond basic uptime checks, your PHP application needs granular health monitoring. This involves not just checking if the web server is responding, but if the application itself is functional and performing within acceptable parameters. A common approach is to implement a dedicated health check endpoint within your PHP application. This […]

How to Debug and Fix memory leaks and socket exhaustion in daemon processes in Modern C++ Applications

Diagnosing Memory Leaks in C++ Daemons Memory leaks in long-running daemon processes are insidious. They manifest as a gradual increase in memory consumption, eventually leading to performance degradation, OOM (Out Of Memory) killer invocation, or outright crashes. In C++, these leaks often stem from unmanaged dynamic memory allocations, particularly within complex object lifecycles or when […]
