When you're monitoring infrastructure with OpenTelemetry, the Host Metrics Receiver (hostmetrics) is one of the most relevant components to reach for.

It fully replaces traditional agents (like Prometheus Node Exporter), and collects essential system metrics such as CPU, memory, disk, and network usage directly from the machine where the Collector is running.

Because this receiver needs direct access to the underlying system, it's intended to be used when the Collector is deployed as an Agent. For example, as a DaemonSet on Kubernetes nodes or as a service on a VM or bare-metal host, not as a centralized gateway.

In this guide, you'll learn how to configure it as a Node Exporter alternative for monitoring your server infrastructure.

“Move to kubernetes to save costs” they said in the early days of the k8s frenzy. This was trusting that an efficient pod bin (node) packing would save on node costs (there’s also autoscale but regular cloud already offers that).

The reality is that the overhead costs of running the control plane and auxiliary services in each node (DNS, metric and log collectors etc) plus extra easy ways to make costly mistakes turns most Kubernetes installations a more expensive proposition than running the workloads without it.

For the record, the great thing about k8s and the reason for its success (besides resume-driven technology) is in the standardization it provides and its extensibility or modularity (this plug-in advantage is the reason mediocre software like Wordpress is successful for example).

Managed k8s in the “big three” public cloud providers: Amazon Elastic Kubernetes Service (EKS) in AWS, Google Kubernetes Engine (GKE) in GCP and Azure Kubernetes Service (AKS) in Azure for a startup is expensive.

On the other hand I don’t want to manage k8s master nodes and essential services on “baremetal” — funny that nowadays that means a Virtual Machine (VM), so I was looking for an intermediate solution between the expensive fully managed k8s and the cheapest (in dollars, not in time) completely self-managed k8s.

A Kubernetes Cluster API control plane provider that enables management of hosted control planes as first-class Kubernetes resources. This provider allows you to create and manage highly available Kubernetes control plane components (API Server, Controller Manager, Scheduler, and etcd) as hosted services, decoupling them from the underlying infrastructure.

In a Kubernetes (k8s) cluster, when Pods access external services, their Egress IP addresses are not fixed. In the Overlay network, the Egress IP address is determined by the node where the Pod resides. While in the Underlay network, Pods directly use their own IP addresses for external communication. Consequently, when Pods are rescheduled, regardless of the network mode, their IP addresses for external communication change. This instability poses a challenge for system administrators in managing IP addresses, especially as the cluster scales and during network fault diagnostics. Controlling egress traffic based on a Pod's original egress IP outside the cluster becomes difficult.

To solve this problem, EgressGateway has been introduced into the k8s cluster. It is an open-source EgressGateway designed to resolve egress egress IP address issues across various CNI network modes, such as Calico, Flannel, Weave, and Spiderpool. Through flexible configuration and management of egress policies, EgressGateway allows setting egress IP addresses for tenant-level or cluster-level workloads. When Pods need to access the external network, the system consistently uses the configured Egress IP as the egress address, providing a stable solution for egress traffic management.

taws provides a terminal UI to interact with your AWS resources. The aim of this project is to make it easier to navigate, observe, and manage your AWS infrastructure in the wild.

Worktrunk is a CLI for git worktree management, designed for running AI agents in parallel.

Worktrunk's three core commands make worktrees as easy as branches. Plus, Worktrunk has a bunch of quality-of-life features to simplify working with many parallel changes, including hooks to automate local workflows.
