Tutorial: Run Grafana on Google Cloud?

8 minutes read

Running Grafana on Google Cloud is a straightforward process that allows you to take advantage of the cloud infrastructure and benefits provided by Google. Here's an overview of the steps involved in this tutorial:

  1. Sign in to the Google Cloud Console: Start by signing in to the Google Cloud Console using your Google account.
  2. Create a new project: Create a new project in the Google Cloud Console. This project will serve as a container for your Grafana deployment.
  3. Enable the necessary APIs: Enable the necessary APIs for your project, specifically the Compute Engine API and the Cloud SQL Admin API. These APIs are required for running Grafana on Google Cloud.
  4. Set up a virtual machine: Create a Compute Engine virtual machine instance on Google Cloud. This instance will host and run Grafana.
  5. Install Grafana: Connect to the virtual machine and install Grafana. You can choose to use the package manager of your operating system or download and install Grafana manually.
  6. Configure Grafana: Once Grafana is installed, configure it by modifying the configuration file. You can specify settings such as database connection details, authentication, and other options.
  7. Set up a database: Create a Cloud SQL instance on Google Cloud to serve as the backend database for Grafana. This instance can be MySQL or PostgreSQL, depending on your preference.
  8. Connect Grafana to the database: Configure Grafana to connect to the Cloud SQL database. This involves providing the necessary connection details in Grafana's configuration file.
  9. Set up firewall rules: Configure the firewall rules to allow access to Grafana from the internet. This ensures that you can access Grafana's user interface from anywhere.
  10. Access Grafana: Finally, access Grafana through a web browser by entering the IP address or domain name of your virtual machine instance. You will be able to log in and start using Grafana to visualize and analyze your data.


By following these steps, you can successfully run Grafana on Google Cloud and leverage the cloud infrastructure to manage and monitor your data effectively.

What are the system requirements for running Grafana on Google Cloud?

The system requirements for running Grafana on Google Cloud are as follows:

  1. Operating System: Any Linux distribution (e.g., Ubuntu, CentOS, or Debian) supported by Google Cloud.
  2. CPU: At least 2 CPU cores. The recommended amount may vary depending on your usage patterns and the number of dashboards and panels.
  3. Memory: At least 2 GB of RAM. The amount of memory required will depend on the amount of data being visualized and the number of concurrent user sessions.
  4. Storage: At least 10 GB of storage for the Grafana installation, dashboards, and data sources. It is recommended to use a persistent disk or Managed Storage service for data persistence.
  5. Network: A stable internet connection with appropriate firewall rules to allow inbound and outbound traffic to and from the Grafana server.
  6. Google Cloud Services: Access to necessary Google Cloud services like Compute Engine, Cloud Storage, and Databases, depending on your specific requirements.


Note: These requirements are basic guidelines and may vary based on your specific use case and the scale of your Grafana deployment.


How to set up Grafana to access logs from Google Cloud Logging?

To access logs from Google Cloud Logging in Grafana, you can follow these steps:

  1. Install Grafana: Start by installing Grafana on your preferred operating system. You can find the installation instructions for your specific OS in the Grafana documentation.
  2. Set up a Google Cloud project: Create a new Google Cloud project or use an existing one. Ensure that the necessary permissions are set for accessing the logs.
  3. Create a service account: Generate a service account credential for accessing Google Cloud Logging. You can create a new service account in the Google Cloud Console by navigating to the IAM & Admin → Service accounts section. Assign the necessary permissions, such as the "Logs Viewer" role.
  4. Download the JSON key file: After creating the service account, download the corresponding JSON key file associated with it. This key will be required for authentication with Google Cloud Logging.
  5. Install and configure the Google Cloud Logging data source plugin: In Grafana, install the Google Cloud Logging data source plugin. This plugin enables Grafana to fetch logs from Google Cloud Logging. To install the plugin, go to Configuration → Plugins, search for "Google Cloud Logging" in the Plugins tab, and click on the Install button.
  6. Configure the Google Cloud Logging data source: After installing the plugin, configure it by navigating to Configuration → Data Sources, selecting "Google Cloud Logging" as the data source, and providing the necessary details such as a name, project ID, authentication method, and credentials (the JSON key file downloaded earlier).
  7. Test the data source connection: Once the configuration is completed, click on the "Save & Test" button to verify the connection to Google Cloud Logging. If the connection is successful, you should see a confirmation message.
  8. Create a dashboard using Google Cloud logs: Now, you can create a new dashboard or modify an existing one to include logs from Google Cloud Logging. Add panels to your dashboard and utilize the logs fetched from Google Cloud Logging as required.


By following these steps, you will be able to set up the integration between Grafana and Google Cloud Logging, enabling you to access and visualize your logs effectively.


What is Grafana's API and how to use it on Google Cloud?

Grafana's API is a set of endpoints that allows users to programmatically interact with Grafana, a popular open-source analytics and monitoring platform. The API enables various operations such as creating and managing dashboards, panels, users, alerts, annotations, data sources, and more.


To use Grafana's API on Google Cloud, you can follow these general steps:

  1. Set up a Grafana instance on Google Cloud: Use a virtual machine (VM) or container to install Grafana. You can find detailed installation instructions on the Grafana website.
  2. Configure Grafana API settings: Once the Grafana instance is running, navigate to the Grafana web interface and log in. Go to the main Configuration section, and under the API Access tab, create an API key that will be used for authentication.
  3. Generate the API key: In the Grafana UI, navigate to "Configuration" -> "API Keys" -> "Add API Key". Give it a name and set the desired permissions, for example, to read and write dashboards or manage data sources.
  4. Explore the API documentation: Grafana provides extensive documentation for its API, which can be found on the Grafana website (https://grafana.com/docs/http_api/). Refer to the documentation to understand the available endpoints and corresponding parameters.
  5. Use an HTTP library or tool to interact with the API: You can make HTTP requests to Grafana's API endpoints using any programming language or tool that supports sending HTTP requests. Some popular choices include cURL, Python's requests library, or Google Cloud's Cloud Functions.
  6. Authenticate and send requests: When sending API requests, use the generated API key for authentication. Include the key in the request headers (Authorization: Bearer YOUR_API_KEY) or as a query parameter (?api_key=YOUR_API_KEY).
  7. Parse the API responses: Grafana's API responses are typically returned in JSON format. Parse the responses in your chosen programming language to extract the information you need.


By using Grafana's API on Google Cloud, you can automate Grafana configurations, data retrieval, and visualization processes, integrating it with other services or creating custom monitoring solutions.
