How to monitor etcd

Learning how to monitor etcd is of vital importance when running Kubernetes in production. Monitoring etcd will let you validate that the service performs as expected, while detecting and troubleshooting issues that could take your entire infrastructure down. Keep reading to learn how you can collect the most important metrics from etcd and use them to monitor this service. etcd is a foundational component of the Kubernetes control plane.

Enabling Microsegmentation with Calico Enterprise

Microsegmentation is a security technique that is used to isolate workloads from one another. Microsegmentation limits the blast radius of a data breach by making network security more granular. Should a breach occur, the damage is confined to the affected segment. Application workloads have evolved over time – starting from bare metal, to a mix of on-prem and cloud virtual machines and containers.

Exporters and Target Labels

When monitoring third-party applications with Prometheus, you’ll need an exporter if the application doesn’t already expose metrics in the appropriate format. How do you find an appropriate exporter, and once you have your exporters, how should you organize your label taxonomies to reflect your infrastructure? Many applications in the systems you’re in charge of will be third-party applications, which do not natively expose Prometheus-formatted metrics.

Kublr, enterprise-grade Kubernetes | Zero Downtime Cluster Updates & Upgrades

Centrally deploy, run, and manage Kubernetes clusters across all of your environments with a comprehensive container orchestration platform that finally delivers on the Kubernetes promise. Optimized for large enterprises, Kublr is designed to provide multi-cluster deployments and observability. We made it easy, so your team can focus on what really matters: innovation and value generation.

KMC - Automated Optimization of Kubernetes Performance

Using the Rancher platform and services, enterprise IT and DevOps teams can overcome the complexity of standing up and running multiple Kubernetes containers. However, as deployments scale, and the number of apps and workloads that teams have running on Kubernetes multiplies, complexity grows exponentially. Much of the difficulty centers on trying to find the best configuration settings for applications. Manual, trial-and-error approaches are ineffective, and always overprovisioning isn’t a viable strategy.

Secure Access to PostgreSQL with Pgweb

PostgreSQL is an open source database known for its reliability and performance. It’s used across many industries and applications, and is especially a favorite of web developers. All major web frameworks support PostgreSQL natively, from node.js and Django to Rails and Spring, so its adaptation is relatively broad across the internet for site backend systems. As with any database, developers need tools to work with them. Pgweb is an open source, web-based client for PostgreSQL.

Using Konvoy to Patch your Cluster Infrastructure (Part 1)

Recently we hit the infamous kmem bug in our internal Production Konvoy Cluster. We discovered that we were having this issue after users began reporting a particular CI Job was failing intermittently throughout the Cluster with the following error: From the Pod Logs: From the Kernel Logs.

How to Use the New Sumo Logic Terraform Provider for Hosted Collectors

Automation is a key component in the management of the entire software release lifecycle. While we know it is critical to the Continuous Integration/Continuous Delivery process, it is now becoming equally essential to the underlying infrastructure you depend on. As automation has increased, a new principle for managing infrastructure has emerged to prevent environment drift and ensure your infrastructure is consistently and reliably provisioned.

Monitor and Optimize Your Rancher Environment with Datadog

Many organizations use Kubernetes to quickly ship new features and improve the reliability of their services. Rancher enables teams to reduce the operational overhead of managing their cloud-native workloads — but getting continuous visibility into these environments can be challenging. In this post, we’ll explore how you can quickly start monitoring orchestrated workloads with Rancher’s built-in support for Prometheus and Grafana.

Enterprise Security Controls for Kubernetes

In this talk, we will explore how to meet common enterprise security control needs when running Kubernetes. Specifically, we will look at a range of common enterprise security needs and how you can meet these with standard Kubernetes primitives and open source projects such as Calico, or take it a step further with the additional features of Calico Enterprise.
