# Gemini CLI Extension - Cloud SQL for PostgreSQL Observability
> [!NOTE]
> This extension is currently in beta (pre-v1.0), and may see breaking changes until the first stable release (v1.0).
This Gemini CLI extension provides a set of tools to interact with [Cloud SQL for PostgreSQL](https://cloud.google.com/sql/docs/postgres) monitoring metrics. It allows you to fetch a wide range of database metrics, enabling comprehensive monitoring of database performance and health directly from the [Gemini CLI](https://google-gemini.github.io/gemini-cli/), using natural language prompts.

## Why Use the Cloud SQL for PostgreSQL Observability Extension?
* **Natural Language Management:** Stop wrestling with complex monitoring queries. Explore monitoring data by describing what you want in plain English.
* **Seamless Workflow:** As a Google-developed extension, it integrates seamlessly into the Gemini CLI environment. No need to constantly switch contexts for common tasks.
## Prerequisites
Before you begin, ensure you have the following:
* [Gemini CLI](https://github.com/google-gemini/gemini-cli) installed with version **+v0.6.0**.
* Setup Gemini CLI [Authentication](https://github.com/google-gemini/gemini-cli/tree/main?tab=readme-ov-file#-authentication-options).
* A Google Cloud project with the **Cloud Monitoring API** enabled.
* Ensure [Application Default Credentials](https://cloud.google.com/docs/authentication/gcloud) are available in your environment.
* IAM Permissions:
* Monitoring Viewer (`roles/monitoring.viewer`)
## Getting Started
### Installation
To install the extension, use the command:
```bash
gemini extensions install https://github.com/gemini-cli-extensions/cloud-sql-postgresql-observability
```
### Configuration
Ensure [Application Default Credentials](https://cloud.google.com/docs/authentication/gcloud) are available in your environment.
### Start Gemini CLI
To start the Gemini CLI, use the following command:
```bash
gemini
```
## Usage Examples
Interact with Cloud Monitoring metrics using natural language right from your IDE:
* "What is the memory usage for my Postgres database?"
* "What is the overall system performance for my instance?"
* "What queries have been run for this instance over the last 3 hours?"
* "Provide the execution time for the query X"
## Supported Tools
* `get_system_metrics`: Fetches system level cloud monitoring data (timeseries metrics) for a Postgres instance using a PromQL query.
* `get_query_metrics`: Fetches query level cloud monitoring data (timeseries metrics) for queries running in Postgres instance using a PromQL query.
## Additional Extensions
Find additional extensions to support your entire software development lifecycle at [github.com/gemini-cli-extensions](https://github.com/gemini-cli-extensions), including:
* [Cloud SQL for PostgreSQL extension](https://github.com/gemini-cli-extensions/cloud-sql-postgresql-observability)
* [Generic PostgreSQL extension](https://github.com/gemini-cli-extensions/postgres)
* and more!
## Troubleshooting
Use `gemini --debug` to enable debugging.
Common issues:
* "failed to find default credentials: google: could not find default credentials.": Ensure [Application Default Credentials](https://cloud.google.com/docs/authentication/gcloud) are available in your environment. See [Set up Application Default Credentials](https://cloud.google.com/docs/authentication/external/set-up-adc) for more information.
* "✖ Error during discovery for server: MCP error -32000: Connection closed": The database connection has not been established. Ensure your configuration is set via environment variables.
* "✖ MCP ERROR: Error: spawn /Users/USER/.gemini/extensions/cloud-sql-postgresql-observability/toolbox ENOENT": The Toolbox binary did not download correctly. Ensure you are using Gemini CLI v0.6.0+.
* "cannot execute binary file": The Toolbox binary did not download correctly. Ensure the correct binary for your OS/Architecture has been downloaded. See [Installing the server](https://googleapis.github.io/genai-toolbox/getting-started/introduction/#installing-the-server) for more information.
