Adding Prometheus User to PostgreSQL and Executing bareos-exporter-postgresql.py

To integrate Bareos Exporter with Prometheus and PostgreSQL, follow these steps:

sudo apt install python3-psycopg2 sudo apt install python3-pip pip3 install prometheus_client

1. Adding Prometheus User to PostgreSQL:

   • Log in to your PostgreSQL database as a superuser.
   • Create a new user for Prometheus by running the following command:

     CREATE USER prometheus WITH PASSWORD 'your_password';
     

   • Grant necessary privileges to the Prometheus user:

     GRANT SELECT ON TABLE pool TO prometheus;
     GRANT SELECT ON TABLE media TO prometheus;
     GRANT SELECT ON TABLE log TO prometheus
     

   • exit the PostgreSQL database.

2. Executing bareos-exporter-postgresql.py:

   • Clone the Bareos Exporter repository to your desired location:

     git clone https://github.com/bareos/bareos-exporter.git
     

   • Navigate to the bareos-exporter directory:

     cd bareos-exporter
     

   • Install the required dependencies:

     pip install -r requirements.txt
     

   • Edit the bareos-exporter-postgresql.py file and update the PostgreSQL connection details, including the host, port, database name, username, and password.
   • Save the changes and exit the file.
   • Run the bareos-exporter-postgresql.py script:

     python bareos-exporter-postgresql.py
     

   • The Bareos Exporter should now be running and exposing metrics for Prometheus to scrape.
