Detailed Description

Container monitoring plugin for Docker and Kubernetes metrics.

This plugin extracts container-related collectors from the core library, making them optional for non-containerized environments. The plugin supports:

• Docker container metrics via Docker API or cgroups
• Kubernetes pod/deployment metrics (when K8s support is enabled)
• cgroup-based metrics for any container runtime

Usage:

#include <kcenon/monitoring/plugins/container/container_plugin.h>
 
// Create plugin with default configuration
auto plugin = container_plugin::create();
 
// Or with custom configuration
container_plugin_config config;
config.enable_docker = true;
config.enable_kubernetes = false;
config.docker_socket = "/var/run/docker.sock";
auto plugin = container_plugin::create(config);
 
// Check if running in container before loading
if (container_plugin::is_running_in_container()) {
    collector.register_plugin(std::move(plugin));
}
