Grafana is a popular tool for data visualization and system monitoring. It allows you to create beautiful dashboards to display various metrics and logs. In this tutorial, we'll look at how to install Grafana on Ubuntu and set up advanced examples configurations.

Step 1: Install Grafana

Follow these instructions to install Grafana on Ubuntu:

1. Open a terminal and run the following commands:

sudo apt-get update
sudo apt-get install -y apt-transport-https software-properties-common wget
wget -q -O - <https://packages.grafana.com/gpg.key> | sudo apt-key add -
sudo add-apt-repository "deb <https://packages.grafana.com/oss/deb> stable main"
sudo apt-get update
sudo apt-get install -y grafana

Step 2: Setting up Grafana

After installing Grafana, you need to configure it to use advanced configuration examples. Follow these steps:

1. Open a web browser and go to http://localhost:3000. You will be asked to enter a name user (default admin) and password (default admin).
2. After logging in, you will be prompted to change the administrator password. Follow the instructions on the screen, to change your password.
3. After changing your password, you will be redirected to the Grafana home page.
4. Click on "Configuration" (Settings) in the side menu and select "Data Sources" (Sources data).
5. Click on "Add data source" (Add Data Source) and select the data source you are working with want to work.
6. Enter the necessary parameters to connect to your data source and click on "Save & Test" (Save and Test) to make sure the connection is working correctly.

You now have Grafana installed and configured on Ubuntu, and you are ready to use the advanced configuration examples to create your own dashboards and data visualizations.

Creating a dashboard for Grafana: logs

In Grafana you can create dashboards to visualize your system logs. In this section, we will look at the basic steps for creating a dashboard to display logs.

Step 1: Create a data source

Before creating a dashboard, you need to configure the source data for logs. You can use various data sources such as Elasticsearch, Prometheus and others. For example, let's say we're using Elasticsearch.

1. Open Grafana and go to the "Configuration" section (Settings) in the side menu.
2. Click on "Data Sources" (Data Sources) and select "Add data source" (Add source data).
3. Select Elasticsearch as the data source type.
4. Specify the Elasticsearch URL, authentication information (if required), and other parameters required for connections to your log system.
5. Click on "Save & Test" (Save and Check) to ensure the data source is configured Right.

You now have Grafana installed and configured on Ubuntu, and you are ready to use the advanced configuration examples to create your own dashboards and data visualizations.

4. Specify the Elasticsearch URL, authentication information (if required), and other parameters required for connections to your log system.
5. Click on "Save & Test" (Save and Check) to ensure the data source is configured Right.

Step 2: Create a dashboard

Now that the data source is configured, you can start creating a dashboard to display your logs.

1. In the upper left corner of Grafana, click on the plus sign (+) and select "Dashboard" (Dashboard).
2. Click on "Add new panel" (Add New Panel) and select the panel type, for example, "Graph" (Schedule).
3. In the panel settings, select the data source that you configured in the previous step.
4. Set up a query against log data using a Grafana query language such as Lucene or Elasticsearch Query DSL.
5. Customize the appearance of the panel by adjusting axes, colors, and other parameters.
6. Repeat steps 2-5 to create other dashboard panels that display different aspects of your system logs.
7. Click on "Save" (Save) to save the dashboard.

Now you have a ready-made dashboard for displaying logs in Grafana. You can customize it further, add filters, notifications and other features to get get maximum benefit from visualizing your system logs.

Example of setting up Grafana for Laravel

To configure Grafana for use with Laravel, run next steps:

1. Install and configure Grafana following the instructions in the Grafana documentation.
2. Open the Grafana web interface in a web browser.
3. In the side menu, select "Configuration" (Settings) and then "Data Sources" (Sources data).
4. Click on "Add data source" (Add Data Source) and select "MySQL" (or another base data that Laravel uses) as its data source type.
5. Fill in the required parameters to connect to your Laravel database such as host, port, name user and password.
6. Click on "Save & Test" (Save and Test) to make sure the connection is working correctly.

You now have a data source configured to work with Laravel database in Grafana. You can create panels and dashboards using data from your Laravel applications.

For example, you can create a panel displaying the number of registered users on your system based on data from the "users" table. Or you can create a dashboard that displays the number of requests made to your API based on data from a table "api_logs".

Use the Grafana query language, such as MySQL Query Language or other supported query languages, to create queries against your database and displaying results in Grafana panels.

Have fun setting up Grafana for your Laravel project!
