Installing SQLAdmin on Ubuntu
To monitor database performance with SQLAdmin on Ubuntu, start by installing the tool. For MySQL databases, run:
sudo apt update && sudo apt install sqladmin
For PostgreSQL, use:
sudo apt update && sudo apt install sqladmin-pg
This installs the SQLAdmin package and its dependencies.

Configuring SQLAdmin for Database Connection
After installation, configure SQLAdmin to connect to your database by editing its configuration file. The file path varies by database type:

Add or modify the following parameters with your database credentials:

[mysql]  # For MySQL; use [postgresql] for PostgreSQL
host = localhost
port = 3306  # Default MySQL port; 5432 for PostgreSQL
user = your_db_username
password = your_db_password
database = your_db_name

Save the file once configured.

Starting and Enabling SQLAdmin Service
Launch the SQLAdmin service with:
sudo systemctl start sqladmin
To ensure it starts automatically on boot, enable the service:
sudo systemctl enable sqladmin
Check the service status with sudo systemctl status sqladmin to confirm it’s running.

Accessing the SQLAdmin Web Interface
Open a web browser and navigate to the default SQLAdmin URL (replace your_server_ip with your actual server IP):

Log in using the credentials you set in the configuration file. This grants access to the monitoring dashboard.

Monitoring Performance via the Web Interface
Once logged in, use the following features to monitor performance:

Setting Performance Alerts
Configure alerts to get notified when performance metrics exceed thresholds. In the SQLAdmin interface:

  1. Navigate to the Alerts section.
  2. Click Add Alert and specify:
    • Metric: Choose the metric to monitor (e.g., cpu_usage, memory_usage).
    • Threshold: Set the threshold (e.g., 80% for CPU usage).
    • Notification Method: Select email or other methods to receive alerts.
      Save the alert to activate it.

Optional: Using Third-Party Tools for Enhanced Monitoring
For more advanced monitoring, integrate SQLAdmin with tools like:
