    Proxmox Datacenter Manager: Centralized Control for Modern Virtual Infrastructures

    Proxmox Datacenter Manager is a centralized open-source management solution for distributed infrastructures. With its unified web interface you can easily monitor and control multiple Proxmox remotes, see health and performance at a glance, and coordinate key operations across clusters and data centers.

    I found this software on this link it seems like, Proxmox want to follow VMware to manage all VM / Host in one device

    Proxmox also mention that Customers with active Enterprise Support for their Proxmox remotes also gain access to Proxmox Datacenter Manager updates and support.

    2025 so many new technology need to be explorer. IT keep growing seems too fast for me to catch it up.

  • Monitor your network from a single dashboard

    Monitor your network from a single dashboard

    One solution to manage your network, firewall, server, VM & etc

    Zabbix is an open-source monitoring platform used to track the performance, health, and availability of IT systems.

    I kinda love Zabbix by the how it can modified or edit to show dashboard. It can either be use with SNMP v3 or agent to be monitored. I also configured it to sent to my telegram group to get notified what current happening to my infra. Zabbix Telegram Guide

    Zabbix provide installation guide which you can find through their official website.

    You can find Zabbix installation through this link Click Here To Enter Zabbix Installation

    a) Install and configure Zabbix for your platform# wget https://repo.zabbix.com/zabbix/7.4/release/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest_7.4+ubuntu24.04_all.deb
    # dpkg -i zabbix-release_latest_7.4+ubuntu24.04_all.deb
    # apt update
    b) Install Zabbix server, frontend, agent2# apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent2
     c) Install Zabbix agent 2 plugins

    You may want to install Zabbix agent 2 plugins.
    # apt install zabbix-agent2-plugin-mongodb zabbix-agent2-plugin-mssql zabbix-agent2-plugin-postgresql
    Install mysql-server

    I found this need to be install to run create initial database
    sudo apt install mysql-server
    mysql-server secure installation (Zabbix will work even if you don’t run it.)

    this not necessary to configure

    Running it improves database security by:
    Setting root password
    Removing anonymous users
    Disabling remote root login
    Removing test database
    Reloading privileges
    sudo mysql_secure_installation
    d) Create initial database

    Run the following on your database host.
    # mysql -uroot -p
    password
    mysql> create database zabbix character set utf8mb4 collate utf8mb4_bin;
    mysql> create user zabbix@localhost identified by ‘password’;
    mysql> grant all privileges on zabbix.* to zabbix@localhost;
    mysql> set global log_bin_trust_function_creators = 1;
    mysql> quit;
    On Zabbix server host import initial schema and data. You will be prompted to enter your newly created password.
    # zcat /usr/share/zabbix/sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix
    Disable log_bin_trust_function_creators option after importing database schema.
    # mysql -uroot -p
    password
    mysql> set global log_bin_trust_function_creators = 0;
    mysql> quit;
    e. Configure the database for Zabbix server
    Edit file /etc/zabbix/zabbix_server.conf
    DBPassword=password
    f. Start Zabbix server and agent processes

    Start Zabbix server and agent processes and make it start at system boot.
    # systemctl restart zabbix-server zabbix-agent2 apache2
    # systemctl enable zabbix-server zabbix-agent2 apache2
    g. Open Zabbix UI web page
    The default URL for Zabbix UI when using Apache web server is http://host/zabbix

    Zabbix also offer a wide range of paid professional services that are designed to fit your unique business requirements.

  • Hypervisor for your server

    Hypervisor for your server

    Here are listing for Hypervisor kernal based

    Hyper-V

    Microsoft Hyper-V is a built-in hypervisor for Windows (Pro, Enterprise, Education) and Windows Server that lets you create and run virtual machines (VMs). It allows multiple operating systems to run on a single physical machine, making it useful for testing, development, or enterprise virtualization. As a Type 1 hypervisor, Hyper-V runs directly on the hardware, offering features like live migration, high availability, and network isolation. You can manage it using various built-in tools.

    Many users have migrated to Nutanix or VMware, but these platforms are still widely used by companies to create virtual machines, such as for Active Directory. I previously created AD1 and AD2 on the same server to fulfil customer need based on provided hardware.

    Red Hat Enterprise Linux (RHEL)

    Red Hat Enterprise Linux (RHEL) is a commercial Linux distribution developed by Red Hat. It’s designed for enterprises and organizations that need a stable, secure, and supported operating system for servers, workstations, and cloud environments. RHEL provides long-term support, regular security updates, and certified software packages, making it ideal for production environments, critical applications, and enterprise workloads.

    I am not very familiar with Red Hat, but I am aware that some users are still renewing their licenses, and certain licenses include direct support from Red Hat.

  • Top picks hypervisor for hosting virtual machine

    A hypervisor is software that allows one physical computer (server) to run multiple virtual machines (VMs) at the same time.

    There are two type of hypervisor :

    1. Bare Metal
    2. Hosted on OS

    Mostly companies will use either VMware, Nutanix, Windows Hyper-V or etc

    There are so many including paid and open-source

    (Bare-metal)

    Nutanix is a technology company that provides a platform to run virtual machines, storage, and networking in a simple, unified system.

    It is best known for hyper-converged infrastructure (HCI), which means:

    It combines compute + storage + virtualization into one easy-to-manage platform.

    But it need its support hardware for it. Need to check with disti for.

    (Bare-metal)

    VMware is a company and a technology platform that allows you to run multiple virtual machines (VMs) on a single physical server now own by Broadcom in November 2023.

    It so simple to do installation which required to install VMware ESXi

    For manage multiple device required installation VMware vCenter.

    Before this VMware also provide free version ESXI which can operate normally but backup

    (Bare-metal)

    Proxmox VE (Virtual Environment) is a free, open-source virtualization platform used to run virtual machines and containers on a server.

    Most popular using for

    Home labs

    Small businesses

    Learning virtualization

    Even company also use it for small system development

    Another alternative for Proxmox is

    (Bare-metal)

    XCP-ng is a free, open-source virtualization platform (hypervisor) used to run virtual machines (VMs) on physical servers.

    It provides Built-in backup support (with Xen Orchestra)
