When it comes to creating new Pods from a ReplicationController or ReplicaSet, ServiceAccounts for namespaces, or even new EndPoints for a Service, kube-controller-manager is the one responsible for carrying out these tasks. Monitoring the Kubernetes controller manager is fundamental to ensure the proper operation of your Kubernetes cluster. If you are in your cloud-native journey, running your workloads on top of Kubernetes, don’t miss the kube-controller-manager observability.

Tigera provides the industry’s only active Cloud-Native Application Security Platform (CNAPP) for containers and Kubernetes. Available as a fully managed SaaS (Calico Cloud) or a self-managed service (Calico Enterprise), the platform prevents, detects, troubleshoots, and automatically mitigates exposure risks of security issues in build, deploy, and runtime stages across multi-cluster, multi-cloud, and hybrid deployments.

Fact: The Security Operations team at Grafana Labs loves logs. They are a key pillar of observability for many reasons, such as how they are stuffed full of details to help us diagnose the “why?” when things go wrong.

When something goes wrong or looks fishy for a particular host in your infrastructure how do you know who to ask about it? In an infrastructure managed by many and used by many it is also helpful to know what each hosts’ purpose is. In this article we show how to add maintainer and purpose information to individual hosts in your infrastructure via the CMDB feature of Mission Portal. We will also add a Build Module to add this information to the /etc/motd file for each associated host.

File integrity monitoring is an important aspect in managing your infrastructure. Tripwire and AIDE are often cited as necessary tools by compliance frameworks1,2,3. Of course CFEngine can manage a file to make sure it contains desired content, but did you know that CFEngine also has the capability to simply monitor a file for change? In this blog post we take a look at CFEngines’ changes attribute for files promises.
