Detailed Description

Plugin interface for metric collectors.

This file defines the plugin architecture for dynamically loadable metric collectors. It provides a common interface that all collectors must implement, enabling runtime registration, discovery, and lifecycle management.

Design Goals:

• Fewest Elements: Single interface for all collector types
• Reveals Intention: Clear contract for plugin behavior
• Separation of Concerns: Collection logic separate from registration
• Extensibility: Support for both built-in and dynamic plugins

Usage:

class my_collector_plugin : public collector_plugin {
public:
    auto name() const -> std::string_view override {
        return "my_collector";
    }
 
    auto collect() -> std::vector<metric> override {
        // Collect and return metrics
        return metrics;
    }
 
    auto interval() const -> std::chrono::milliseconds override {
        return std::chrono::seconds(5);
    }
 
    auto is_available() const -> bool override {
        // Check platform/resource availability
        return true;
    }
};
 
// Register with registry
registry.register_plugin(std::make_unique<my_collector_plugin>());
