Open Sourcerers
By Robert Baumgartner, Red Hat Austria, February 2023 (OpenShift 4.12) In this blog I will guide you on how to use service performance monitoring (SPM) with Jaeger. It should work with any application that is working with OpenTelemetry. This document is based on OpenShift 4.12. See Distributed tracing release notes. OpenShift distributed tracing platform Operator […]
From Java code in your repo to a running Pod on Kubernetes. This article explains all the steps needed, including basic shortcuts.
By Robert Baumgartner, Red Hat Austria, March 2023 (OpenShift 4.12, OpenShift distributed tracing data collection 0.63) In this blog, I will guide you on how to use OpenTelemetry with a Quarkus application; how to forward your OpenTelemetry information to Tempo and display it in Grafana UI. I will use distributed tracing to instrument my services […]

In this blog I will guide you on How to enable an application performance monitoring (APM). How to scale a user application based on application metrics with a Horizontal Pod Autoscaler (HPA). How to create an alert based on application metrics and send this alert to an external system. For the monitoring, I will use […]
Quickly creating a REST CRUD service with Quarkus, making use of Dev Services for databases and a few extensions to move your service to a Kubernetes cluster.
Part 3 of the article series on automated application packaging and distribution. This time about integrating into Kubernetes Native Pipelines with OpenShift Pipelines (Tekton)
Introduction In this article series we are going to build together a sample cloud-native IoT architecture, called Bobbycar, based on the Red Hat OpenShift Container platform and a lot of other relevant technologies. The first part of the series should provide you with the necessary background on IoT-, Edge- and Cloud Computing and also briefly […]
Photo by Rene Böhmer on Unsplash By using Quarkus you can write lightweight and lightning-fast Java applications that scale on OpenShift/Kubernetes in a matter of milliseconds. But to achieve linear scalability and resilience of your application you should strive to create stateless applications. If you scale up multiple application instances that all connect to the […]
