The easiest way to get started with Icinga is a single-node installation. If you are new to the Icinga world, here you have a kickstart for installing Icinga 2, Icinga Web 2 and Icinga Director on CentOS 7. With these steps you will have a ready Icinga environment for monitoring your infrastructure.
Metrics and logs go together like cookies and milk. Metrics tell you when you have a problem, and logs/events often tell you why that problem happened. But it’s always been harder than it needed to be to get both types of data onto a single screen, especially when the sysadmins using the tools aren’t necessarily daily experts in managing those monitoring platforms.
Out-of-memory (OOM) errors take place when the Linux kernel can’t provide enough memory to run all of its user-space processes, causing at least one process to exit without warning. Without a comprehensive monitoring solution, OOM errors can be tricky to diagnose. In this post, you will learn how to use Datadog to diagnose OOM errors on Linux systems.
High availability (HA) for MicroK8s, the lightweight Kubernetes, is now available as a tech preview for Linux, Windows and macOS. The Kubernetes control plane can now be distributed across multiple nodes, bringing resiliency to the cluster while maintaining a low footprint using Dqlite, the distributed SQL engine as the Kubernetes datastore.
ROS, Ripple and reflections – In this month’s edition of The State of Robotics, we’ll tell you about the recently discovered Ripple vulnerability, the latest and greatest in robots reflecting nature, and a dash of news from the ROS universe.
Do you have a big data center? Do you have terabytes of confidential data stored in that data center? Are you worried that your data might be exposed to malicious attacks? One of the most prominent security features of storage solutions is encryption at rest. This blog will explain this in more detail and how it is implemented in Charmed Ceph, Canonical’s software-defined storage solution.

Kubeflow Pipelines are a great way to build portable, scalable machine learning workflows. It is a part of the Kubeflow project that aims to reduce the complexity and time involved with training and deploying machine learning models at scale. For more on Kubeflow, read our Kubernetes for data science: meet Kubeflow post.
At Elastic we are constantly innovating and releasing new features. As we release new features we are also working to make sure that they are tested, solid, and reliable — and sometimes we do find bugs or other issues. While testing a new feature we discovered a Linux kernel bug affecting SSD disks on certain Linux kernels. In this blog article we cover the story around the investigation and how it involved a great collaboration with two close partners, Google Cloud and Canonical.
Deploying and monitoring performance for an entire Kubernetes cluster can be complex. To simplify the process, we’ve added service discovery functionality to eliminate complex configuration, in addition to more advanced monitoring for viewing activity inside containers. Service discovery identifies k8s pods running on a cluster and immediately starts monitoring system performance. All containers are identified, regardless of complexity.
