Malachite

Overview

• Malachite is a daemon written in Rust, which is responsible for node-level and cgroup-level metrics collection, e.g., memory usage and network bandwidth.
• Malachite support cgroup, both V1 and V2, which can provide running information of k8s Pods and Containers.
• Malachite mainly obtains relevant metrics from pseudo-filesystems, e.g., /proc and /sys, and expand its capabilities with EBPF program. All of these can be switched on and off dynamically to save metric collection overhead.
