General Introduction
Xata Agent is an open source AI tool designed specifically for PostgreSQL databases. It can automatically monitor the database status, find the root cause of performance problems or failures, and give recommendations for repair. The development team xAI positioned it as a "database expert" assistant , suitable for developers and operations personnel to use . The project is hosted on GitHub, with a current date of March 17, 2025, and serves more than 35,000 active PostgreSQL databases. xata Agent is not only free and open-source, but it also supports extensions that allow users to add tools or tweak settings as needed. It emphasizes security and does not perform any operations that could damage the database, and all diagnostics and recommendations are based on pre-defined SQL commands and analysis logic.
Function List
- real time monitoring: Continuously check the operational status of the database, including connection counts, slow queries, and lock waits.
- Problem diagnosis: Analyze logs and metrics to find the cause of high CPU usage or low memory.
- Optimization Recommendations: Provide specific parameter tuning suggestions, such as memory allocation or connection caps.
- Slow Query Analysis: List the queries that take a long time to execute and give options for improvement.
- Integration of logs and metrics: Support for data from AWS RDS and Aurora via Cloudwatch.
- Extensibility Support: Allows users to add custom tools or playbooks to handle specific tasks.
- notification function: Send issue alerts via Slack for easy and timely team response.
Using Help
Installation process
Xata Agent is required to run with a PostgreSQL database, and the installation process is simple and deployed mainly via Docker. Below are the detailed steps:
- Preparing the environment
- Make sure you have Docker and Docker Compose installed. This can be done with the command
docker --version
cap (a poem)docker-compose --version
Check. - A PostgreSQL database is required to store Xata Agent configuration and historical data.
- Make sure you have Docker and Docker Compose installed. This can be done with the command
- Download Project
- Open a terminal and enter the command Clone Repository:
git clone https://github.com/xataio/agent.git
- Go to the project catalog:
cd agent
- Open a terminal and enter the command Clone Repository:
- Configuring Environment Variables
- In the project root directory, find the
.env.production
file, open it with a text editor. - Set the following required fields:
PUBLIC_URL
: Fill in your access address, e.g.http://localhost:8080
TheOPENAI_API_KEY
: Enter your OpenAI API key (other models like Anthropic or Deepseek are supported).
- Optional: If you use Slack notifications, add Slack-related keys.
- In the project root directory, find the
- Starting services
- Runs in the terminal:
docker-compose up -d
- This will start the Xata Agent and a temporary PostgreSQL database. Wait a few minutes until the terminal shows that the service is running.
- Runs in the terminal:
- access interface
- Open your browser and type
http://localhost:8080
(or the PUBLIC_URL you set). - Follow the page prompts to complete the first-time setup, such as connecting to your target PostgreSQL database.
- Open your browser and type
Main Functions
real time monitoring
- After logging in, the home page displays the current status of the target database, such as the number of active connections and CPU utilization.
- Click on the "Monitor" tab to see a detailed graph of your metrics, with data updated every 10 seconds.
Problem diagnosis
- If there is an abnormality in the database, such as high CPU usage, click the "Diagnostics" button.
- The Xata Agent automatically runs predefined SQL commands (such as checking the
pg_stat_statements
) and then displays the cause of the problem, such as a particular query taking up too many resources.
Optimization Recommendations
- On the Suggestions page, the tool lists the current parameter configurations (e.g.
max_connections
maybeshared_buffers
). - Next to it will be the recommended value and the reason for the adjustment, such as "Increasing the memory allocation reduces disk IO".
Slow Query Analysis
- Go to the Slow Queries tab and the tool will list SQL statements that take longer than 2 seconds to execute.
- Click on a query to see the detailed execution plan and optimization suggestions, such as adding indexes.
caveat
- When using it for the first time, it is recommended to connect to a test database first to make sure it is configured correctly.
- If you need to extend the functionality, you can do so in the
apps/dbagent/src/lib/tools
directory to add custom tools, refer to the official README for details.
application scenario
- Small and medium-sized development teams
Scenario Description: A development team manages multiple PostgreSQL databases but does not have a full-time DBA. Xata Agent automatically monitors the databases, identifies slow queries or excessive connections, and gives optimization suggestions to reduce the team's burden. - Cloud Database Operations
Scenario Description: A PostgreSQL instance running on AWS RDS has a performance bottleneck. Users access Cloudwatch logs via Xata Agent to quickly pinpoint problems, such as latency due to lock waiting, and receive recommendations for tuning parameters. - Open Source Project Maintenance
Scenario description: open source projects need to run a stable database , but limited resources. Xata Agent free and easy to deploy , can real-time monitoring and notify the developer of anomalies through Slack .
QA
- Is Xata Agent free?
Yes, it is an open source tool and completely free. You only need to cover the cost of the running environment, such as Docker server costs. - Will it modify my database?
No. Xata Agent only runs read-only diagnostic commands and does not perform any change operations; all recommendations need to be implemented manually. - What databases are supported?
Currently only PostgreSQL is supported, including cloud service versions such as RDS and Aurora.
