Linux System Performance/Observability Tools BPF (bpfcc-tools), BCC Tools, and Complete Observability Toolkit Assuming you have Linux Server in place and have the required BPF aka BCC related packages installed on the system(s) for Linux distribution. BPF(eBPF) aka BCC Tools (bpfcc-tools): BPF , which originally stood for Berkley Packet Filter is the dynamic tracing tools for Linux Systems. BPF initially used for the speeding up for the tcpdump expressions and since then it has been know as the extended Berkley packet Filter (eBPF). Its new uses are Tracing Tools where it provides programmability for the BPF Compiler Collection (BCC) and bpftrace front ends. Example: execsnoop, biosnoop etc is a BCC Tool. When facing production performance crisis these such list of tools comes handy to trace and fix the issue. However, it requires certain KERNEL level config options to be enabled such as CONFIG_FTRACE, CONFIG_BPF. Profiling tools typically required complie...

EKS Cluster and Create CSI Driver to Store Credentials in AWS Secrets Manager Setup EKS Cluster and Manage Credentials at Runtime using CSI Driver with SecretProviderClass and AWS Secrets Manager Assuming you have configured/installed AWS CLI, EKSCTL, KUBECTL, and HELM. 📦 CSI Basic Information CSI (Container Storage Interface) is widely used as a Storage Technology. Created by Google | Mesosphere | Docker. It has two plugins : one runs on the Master Node (Centralized Controller Plugin) and another on Worker Nodes (Decentralized headless Node Plugin). CSI communication protocol is gRPC. The communication between Container Orchestration to Controller Plugin (Master) and to Node Plugin (Worker Node) happens using gRPC . CSI Drivers: vendor-specific, compiled into Kubernetes/OpenShift binaries. To use a CSI driver, a StorageClass needs to be assigned first. The CSI driver is then set as the Provisioner for the Storage Class. CSI drivers provide three main ser...
