PgHero is a powerful tool for monitoring PostgreSQL databases, providing insights into slow queries, index usage, cache hit rates, and more. In this guide, we will show you how to install PgHero on Ubuntu 22.04 to monitor your PostgreSQL databases efficiently. Hosting your database on a WindowsVPS ensures optimal performance and scalability, thanks to the dedicated resources of a VPS server.

Step 1: Update Your VPS Server

Before installing PgHero, make sure your VPS server is up to date. Run the following commands to update the system:

sudo apt update && sudo apt upgrade -y

By hosting your PostgreSQL and PgHero setup on a WindowsVPS, you gain better performance, allowing you to monitor and optimize your database with greater efficiency.

Step 2: Install PostgreSQL

If you haven't already installed PostgreSQL on your server, you can do so with the following command:

sudo apt install postgresql postgresql-contrib -y

Once installed, PostgreSQL will start automatically. You can verify that it’s running using:

sudo systemctl status postgresql

Step 3: Install PgHero

Next, we will install PgHero. First, you need to install Ruby and other dependencies. Run the following commands:

sudo apt install ruby-full -y

Now, install the PgHero gem:

sudo gem install pghero

Step 4: Set Up PgHero with PostgreSQL

After installing PgHero, you need to configure it with your PostgreSQL database. First, switch to the PostgreSQL user:

sudo -i -u postgres

Then, access the PostgreSQL shell:

psql

In the shell, create the pghero extension on your database:

CREATE EXTENSION pghero;
\q

This will install the PgHero extension on your PostgreSQL database.

Step 5: Set Up PgHero Web Interface

To access PgHero via a web interface, you need to configure it to run as a web application. First, install a web server like Puma to run the PgHero web interface. Install Puma by running:

sudo gem install puma

Create a new directory for PgHero and navigate into it:

mkdir ~/pghero_app && cd ~/pghero_app

Create a basic configuration file for PgHero:

nano config.ru

Add the following content to the file:

require "pghero"
run PgHero::App

Start the PgHero web interface using Puma:

puma -p 8080

You can now access the PgHero interface by visiting http://your-server-ip:8080 in your browser.

Step 6: Set Up Systemd Service for PgHero

To keep PgHero running as a background service, it’s best to create a Systemd service. Create a service file by running:

sudo nano /etc/systemd/system/pghero.service

Add the following content to the file:

[Unit]
Description=PgHero Monitoring Tool
After=network.target

[Service]
User=your-username
WorkingDirectory=/home/your-username/pghero_app
ExecStart=/usr/local/bin/puma -p 8080
Restart=always

[Install]
WantedBy=multi-user.target

Save the file, then reload Systemd and start the PgHero service:

sudo systemctl daemon-reload
sudo systemctl start pghero
sudo systemctl enable pghero

Step 7: Access PgHero

After setting up the service, PgHero will run continuously, and you can access it by visiting http://your-server-ip:8080. From the web interface, you can monitor slow queries, index usage, cache hit rates, and more.

Step 8: Optimize Your VPS Server for PgHero

To ensure the best performance for monitoring and optimizing your PostgreSQL database, hosting PgHero on a WindowsVPS is highly recommended. A VPS server provides dedicated resources such as CPU, memory, and storage, which are essential for handling large databases and ensuring that PgHero delivers real-time insights into your database performance.

Conclusion

Installing PgHero on Ubuntu 22.04 allows you to monitor and optimize your PostgreSQL database with ease. By hosting your PostgreSQL and PgHero setup on a WindowsVPS, you can take full advantage of dedicated resources, ensuring that your database performs optimally even under heavy workloads.
