+# Install and configure Prometheus server
+
+Go to the official [Prometheus downloads page](https://prometheus.io/download/) and download the latest package.
+Perform required setup steps.
+
+   ```
+   tar -zxpvf prometheus-2.47.2.linux-amd64.tar.gz
+   useradd -m -s /bin/false prometheus
+   mkdir /etc/prometheus
+   mkdir /var/lib/prometheus
+   chown prometheus /etc/prometheus
+   chown prometheus /var/lib/prometheus/
+
+   cd prometheus-2.47.2.linux-amd64
+   cp prometheus /usr/local/bin

+   cp -r console_libraries /etc/prometheus

+
+# Prepare prometheus config file
+
+All the prometheus configurations should be present in /etc/prometheus/prometheus.yml file.
+You need to register the target in the prometheus.yml file to get the metrics from the source systems.
+
+
+   1. Copy the example prometheus.yml file to your Prometheus server host
+
+   ```
+    scp prometheus.yml /etc/prometheus/prometheus.yml
+   ```
+
+   2. Open the copied file in the edit mode
+
+   ```
+    vi /etc/prometheus/prometheus.yml
+   ```
+
+   3. Replace the *<prometheus_server_ip>* string with the prometheus server ip
+
+   ```
+    static_configs:
+      - targets: ["<prometheus_server_ip>:9090"]
+   ```
+
+   4. Replace all the *<grafana_bridge_ip>* strings with ip of the host running the grafana-bridge
+
+   ```
+   static_configs:
+    - targets: ['<grafana_bridge_ip>:9250']
+   ```
+
+
+# Start Prometheus server
+
+   Reload the systemd service to register the prometheus service and start the prometheus service
+
+   ```
+   systemctl daemon-reload
+   systemctl start prometheus
+   systemctl enable prometheus
+   ```
