Introduction<\/h3>\n

Monitoring server performance is essential to ensure system reliability, identify bottlenecks, and maintain high availability. Prometheus<\/strong> and Grafana<\/strong> are powerful open-source tools that work seamlessly together to collect, visualize, and analyze server metrics in real-time. In this guide, you’ll learn how to set up Prometheus for data collection and Grafana for creating insightful dashboards to monitor your server\u2019s performance.<\/p>\n

Prerequisites<\/h3>\n

Before getting started, ensure you have:<\/p>\n

    \n
  • An Ubuntu 22.04 VPS<\/li>\n
  • Root or sudo privileges<\/li>\n
  • Basic knowledge of Linux commands<\/li>\n<\/ul>\n

    Step 1: Update Your System<\/h3>\n

    Ensure your server is up-to-date to avoid compatibility issues:<\/p>\n

    sudo apt update && sudo apt upgrade -y<\/p><\/blockquote>\n

    Step 2: Install Prometheus<\/h3>\n

    Prometheus is a time-series database designed for monitoring and alerting. Follow these steps to install it:<\/p>\n

    1. Create a Prometheus User:<\/h4>\n

    sudo useradd –no-create-home –shell \/bin\/false prometheus<\/p><\/blockquote>\n

    2. Create Directories for Prometheus Data:<\/h4>\n

    sudo mkdir \/etc\/prometheus
    \nsudo mkdir \/var\/lib\/prometheus<\/p><\/blockquote>\n

    3. Download Prometheus:<\/h4>\n

    cd \/tmp
    \nwget https:\/\/github.com\/prometheus\/prometheus\/releases\/latest\/download\/prometheus-2.43.0.linux-amd64.tar.gz<\/p><\/blockquote>\n

    4. Extract the Archive:<\/h4>\n

    tar -xvf prometheus-2.43.0.linux-amd64.tar.gz<\/p><\/blockquote>\n

    5. Move Binaries:<\/h4>\n

    sudo mv prometheus-2.43.0.linux-amd64\/prometheus \/usr\/local\/bin\/
    \nsudo mv prometheus-2.43.0.linux-amd64\/promtool \/usr\/local\/bin\/<\/p><\/blockquote>\n

    6. Move Configuration Files:<\/h4>\n

    sudo mv prometheus-2.43.0.linux-amd64\/consoles \/etc\/prometheus
    \nsudo mv prometheus-2.43.0.linux-amd64\/console_libraries \/etc\/prometheus
    \nsudo mv prometheus-2.43.0.linux-amd64\/prometheus.yml \/etc\/prometheus<\/p><\/blockquote>\n

    Step 3: Configure Prometheus<\/h3>\n

    Edit the Prometheus configuration file:<\/p>\n

    sudo nano \/etc\/prometheus\/prometheus.yml<\/p><\/blockquote>\n

    Example configuration:<\/p>\n

    global:
    \nscrape_interval: 15s<\/p>\n

    scrape_configs:
    \n– job_name: ‘prometheus’
    \nstatic_configs:
    \n– targets: [‘localhost:9090’]<\/p><\/blockquote>\n

    Step 4: Set Up Prometheus as a Service<\/h3>\n

    Create a systemd service file:<\/p>\n

    sudo nano \/etc\/systemd\/system\/prometheus.service<\/p><\/blockquote>\n

    Add the following:<\/p>\n

    [Unit]
    \nDescription=Prometheus
    \nWants=network-online.target
    \nAfter=network-online.target<\/p>\n

    [Service]
    \nUser=prometheus
    \nExecStart=\/usr\/local\/bin\/prometheus \\
    \n–config.file=\/etc\/prometheus\/prometheus.yml \\
    \n–storage.tsdb.path=\/var\/lib\/prometheus\/<\/p>\n

    [Install]
    \nWantedBy=multi-user.target<\/p><\/blockquote>\n

    Reload systemd, start, and enable Prometheus:<\/p>\n

    sudo systemctl daemon-reload
    \nsudo systemctl start prometheus
    \nsudo systemctl enable prometheus<\/p><\/blockquote>\n

    Verify Prometheus:<\/h4>\n

    Check if Prometheus is running:<\/p>\n

    sudo systemctl status prometheus<\/p><\/blockquote>\n

    Access Prometheus at:<\/p>\n

    http:\/\/your_server_ip:9090<\/p><\/blockquote>\n

    Step 5: Install Grafana<\/h3>\n

    Grafana is used to visualize the data collected by Prometheus.<\/p>\n

    1. Add Grafana Repository:<\/h4>\n

    sudo apt install -y software-properties-common
    \nsudo add-apt-repository “deb https:\/\/packages.grafana.com\/oss\/deb stable main”<\/p><\/blockquote>\n

    2. Install Grafana:<\/h4>\n

    sudo apt update && sudo apt install grafana -y<\/p><\/blockquote>\n

    3. Start and Enable Grafana:<\/h4>\n

    sudo systemctl start grafana-server
    \nsudo systemctl enable grafana-server<\/p><\/blockquote>\n

    Access Grafana:<\/h4>\n

    Visit Grafana at:<\/p>\n

    http:\/\/your_server_ip:3000<\/p><\/blockquote>\n

    Default login credentials:<\/p>\n

      \n
    • Username: admin<\/strong><\/li>\n
    • Password: admin<\/strong> (change on first login)<\/li>\n<\/ul>\n

      Step 6: Configure Prometheus as a Data Source in Grafana<\/h3>\n
        \n
      1. \n
          \n
        1. Log into Grafana.<\/li>\n
        2. Go to Settings \u2192 Data Sources<\/strong>.<\/li>\n
        3. Click Add data source<\/strong> and select Prometheus<\/strong>.<\/li>\n
        4. Set the URL to:<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

          http:\/\/localhost:9090<\/p><\/blockquote>\n

            \n
          1. Click Save & Test<\/strong>.<\/li>\n<\/ol>\n

            Step 7: Create Dashboards in Grafana<\/h3>\n

            To create a dashboard:<\/p>\n

              \n
            1. \n
                \n
              1. Click the +<\/strong> icon \u2192 Dashboard<\/strong>.<\/li>\n
              2. Click Add new panel<\/strong>.<\/li>\n
              3. In the query field, enter:<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

                node_cpu_seconds_total<\/p><\/blockquote>\n

                  \n
                1. Adjust the visualization settings as needed.<\/li>\n
                2. Click Apply<\/strong> to save the panel.<\/li>\n<\/ol>\n

                  Step 8: Monitor Key Metrics<\/h3>\n

                  Common Prometheus metrics you can track:<\/p>\n

                    \n
                  • CPU Usage:<\/strong>
                    \n

                    rate(node_cpu_seconds_total[1m])<\/p><\/blockquote>\n<\/li>\n

                  • Memory Usage:<\/strong>
                    \n

                    node_memory_MemAvailable_bytes<\/p><\/blockquote>\n<\/li>\n

                  • Disk Usage:<\/strong>
                    \n

                    node_filesystem_avail_bytes<\/p><\/blockquote>\n<\/li>\n

                  • Network Traffic:<\/strong>
                    \n

                    rate(node_network_receive_bytes_total[5m])<\/p><\/blockquote>\n<\/li>\n<\/ul>\n

                    Step 9: Enable Alerts in Grafana<\/h3>\n

                    To set up alerts:<\/p>\n

                      \n
                    1. \n
                        \n
                      1. Go to your dashboard.<\/li>\n
                      2. Click the panel title \u2192 Edit<\/strong>.<\/li>\n
                      3. Go to the Alert<\/strong> tab and click Create Alert<\/strong>.<\/li>\n
                      4. Set conditions like:<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

                        WHEN avg() OF query(A, 5m, now) IS ABOVE 80<\/p><\/blockquote>\n

                          \n
                        1. Save the alert configuration.<\/li>\n<\/ol>\n

                          Step 10: Securing Prometheus and Grafana<\/h3>\n
                            \n
                          • \n
                              \n
                            • Enable authentication for Prometheus by configuring prometheus.yml<\/code>.<\/li>\n
                            • Use HTTPS for Grafana by editing \/etc\/grafana\/grafana.ini<\/code> and configuring SSL.<\/li>\n
                            • Restrict access to monitoring tools using a firewall:<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                              sudo ufw allow 9090\/tcp
                              \nsudo ufw allow 3000\/tcp<\/p><\/blockquote>\n

                              Conclusion<\/h3>\n
