Importing the Debian 12 Cloud Image into Oracle Cloud Infrastructure

Image
Overview This guide walks through importing the official Debian 12 (Bookworm) generic cloud image into Oracle Cloud Infrastructure (OCI) as a custom image, and launching a compute instance from it.  As of now, OCI don't have native platform images for Debian Linux. But in some scenarios, we need to use the Debian Linux image for application deployment. However, Debian is listed as a supported Linux or UNIX-like Operating System on OCI - https://docs.oracle.com/en-us/iaas/Content/Compute/Tasks/importingcustomimagelinux.htm Source image used in this walkthrough: https://cloud.debian.org/images/cloud/bookworm/latest/debian-12-generic-amd64.qcow2 ⚠️ This demonstration is performed in a personal OCI tenancy using test resources only. No customer data, environments, or screenshots are used. High-level flow: •          Download the qcow2 in OCI Cloud Shell •          Stage the qcow2 in ...

Implementing Performance Co-Pilot (PCP) on Enterprise Linux Distributions

  Overview Performance Co-Pilot (PCP) is an open-source, distributed framework for monitoring, visualising, storing, and analysing system-level performance metrics. PCP uses a collector–monitor architecture where Performance Metrics Domain Agents (PMDAs) gather data from different system subsystems and the Performance Metrics Collector Daemon (pmcd) coordinates collection. Metrics are archived by pmlogger for retrospective analysis. PCP replaces the legacy Oracle OSWatcher Black Box (OSWbb) and covers the same ground — CPU, memory, disk I/O, network, and process statistics — while offering binary archive storage, extensible PMDAs, conditional alerting via PMIE, and native Grafana integration. Distribution Compatibility Matrix PCP is included in the base repositories of all major RHEL-family distributions. Since RHEL 8, 9, and 10 all ship PCP in their BaseOS or AppStream repos, and Rocky Linux, AlmaLinux, and Oracle Linux maintain binary or ABI compatibility with RHEL, the ins...
