Many of the benefits of running Kubernetes come from the efficiencies that you get when you share the cluster – and thus the underlying compute and network resources it manages – between multiple services and teams within your organization. Each of these major services or teams that share the cluster are tenants of the cluster – and thus this approach is referred to as multi-tenancy.
Users live in the sunlit world of what they believe to be reality. But, there is, unseen by most, an underworld. A place that is just as real, but not as brightly lit. The Kernel Parameter side (apologies to George Romero). Kernel parameters aren’t really that scary in actuality, but they can be a dark and cobweb-filled corner of the Linux world. Kernel parameters are the means by which we can pass parameters to the Linux (or Unix-like) kernel to control how that it behaves.
October has, as usual, been a busy month, and Sysdig announced many new features. In Sysdig Monitor, we announced the release of four new Advisories and Yaml config support for Advisor.

My father worked with some of the very first computers ever imported to Italy. It was a time when a technician was a temple of excellence built on three pillars: on-the-field experience, a bag of technical manuals, and a fully-stocked toolbox. It was not uncommon that missing the right manual or the correct replacement part turned into a day-long trip from the customers’ site to headquarters and back.
Kubernetes has broken down barriers as the cornerstone of cloud-native application infrastructure in recent years. In addition, cloud vendors offer flexibility, speedy operations, high availability, SLAs (service-level agreement) that guarantee your service availability, and a large catalog of embedded services. But as organizations mature in their Kubernetes journey, monitoring and optimizing costs is the next stage in their cloud-native transformation.
In this previous article, we talked about how to monitor the Istio service mesh in Kubernetes with the out-of-the-box observability stack. This time, we will walk you through monitoring the Istio service mesh with Sysdig Monitor and how to troubleshoot issues. Istio service mesh provides special characteristics and functionalities for microservices running on Kubernetes.
Pod statuses like ImagePullBackOff or ErrImagePull are common when working with containers. ErrImagePull is an error happening when the image specified for a container can’t be retrieved or pulled. ImagePullBackOff is the waiting grace period while the image pull is fixed. In this article, we will take a look at.
Welcome to the September edition of What’s New in Sysdig in 2022! I’m Ayu Shah, Principal Sales Engineer based out of San Francisco Bay Area. I joined Sysdig a little over six months ago and it has been an exciting journey to say the least! I have worn many hats in my career, from Software Engineering to Sales and everything in between.

Monitoring Red Hat OpenShift brings up challenges compared to a vanilla Kubernetes distribution. Discover how Sysdig Monitor, and its exclusive features in OpenShift, will help you monitor and troubleshoot your issues fast and easily. OpenShift builds many out-of-the-box add-ons into its Kubernetes foundation. For example, the OpenShift API server, Controller Manager, Ingress, or Marketplace ecosystem. This creates a more complex environment that can cause you to struggle.
