# Grafana > Steps to configure GreptimeDB as a data source in Grafana using different plugins and data sources, including installation and connection settings. # Grafana GreptimeDB can be configured as a [Grafana data source](https://grafana.com/docs/grafana/latest/datasources/add-a-data-source/). You have the option to connect GreptimeDB with Grafana using one of three data sources: [GreptimeDB](#greptimedb-data-source-plugin), [Prometheus](#prometheus-data-source), or [MySQL](#mysql-data-source). ## GreptimeDB data source plugin The [GreptimeDB data source plugin](https://github.com/GreptimeTeam/greptimedb-grafana-datasource) is based on the ClickHouse data source and adds GreptimeDB-specific features. The plugin adapts perfectly to the GreptimeDB data model, thus providing a better user experience. In addition, it also solves some compatibility issues compared to using the Prometheus data source directly. ### Installation The GreptimeDB Data source plugin can currently only be installed on a local Grafana instance. Make sure Grafana is installed and running before installing the plugin. You can choose one of the following installation methods: - Download the installation package and unzip it to the relevant directory: Grab the latest release from [release page](https://github.com/GreptimeTeam/greptimedb-grafana-datasource/releases/latest/), Unzip the file to your [grafana plugin directory](https://grafana.com/docs/grafana/latest/setup-grafana/configure-grafana/#plugins). - Use grafana cli to download and install: ```shell grafana cli --pluginUrl https://github.com/GreptimeTeam/greptimedb-grafana-datasource/releases/latest/download/info8fcc-greptimedb-datasource.zip plugins install info8fcc ``` - Use our [prebuilt Grafana docker image](https://hub.docker.com/r/greptime/grafana-greptimedb), which ships the plugin by default: `docker run -p 3000:3000 greptime/grafana-greptimedb:latest` Note that you may need to restart your grafana server after installing the plugin. ### Connection settings Click the Add data source button and select GreptimeDB as the type. ![grafana-add-greptimedb-data-source](/grafana-add-greptimedb-data-source.png) Fill in the following URL in the GreptimeDB server URL: ```txt http://:4000 ``` In the Auth section, click basic auth, and fill in the username and password for GreptimeDB in the Basic Auth Details section (not set by default, no need to fill in). - User: `` - Password: `` Then click the Save & Test button to test the connection. ### General Query Settings Before selecting any query type, you first need to configure the **Database** and **Table** to query from. | Setting | Description | | :-------- | :---------------------------------------- | | **Database** | Select the database you want to query. | | **Table** | Select the table you want to query from. | ![DB Table Config](/grafana/dbtable.png) --- ### Table Query Choose the `Table` query type when your query results **do not include a time column**. This is suitable for displaying tabular data. | Setting | Description | | :-------- | :---------------------------------------------- | | **Columns** | Select the columns you want to retrieve. Multiple selections are allowed. | | **Filters** | Set conditions to filter your data. | ![Table Query](/grafana/table.png) --- ### Metrics Query Select the `Time Series` query type when your query results **include both a time column and a numerical value column**. This is ideal for visualizing metrics over time. | Main Setting | Description | | :----------- | :-------------------- | | **Time** | Select the time column. | | **Columns** | Select the numerical value column(s). | ![Time Series](/grafana/series1.png) --- ### Logs Query Choose the `Logs` query type when you want to query log data. You'll need to specify a **Time** column and a **Message** column. | Main Setting | Description | | :----------- | :---------------------------- | | **Time** | Select the timestamp column for your logs. | | **Message** | Select the column containing the log content. | | **Log Level**| (Optional) Select the column representing the log level. | ![Logs](/grafana/logs.png) #### logs Context Query Logs Context Query Performs an approximate time range query based on the value of context columns in a log row. * First, set the context column in Connection Page. ![Context Config](/grafana/context2.png) * Then, when making a query, include the context column in the query. ![Query Config](/grafana/context1.png) --- ### Traces Query Select the `Traces` query type when you want to query distributed tracing data. | Main Setting | Description | | :-------------------- | :------------------------------------------------------------------------------------------------------ | | **Trace Model** | Select `Trace Search` to query a list of traces. | | **Trace Id Column** | Default value: `trace_id` | | **Span Id Column** | Default value: `span_id` | | **Parent Span ID Column** | Default value: `parent_span_id` | | **Service Name Column** | Default value: `service_name` | | **Operation Name Column** | Default value: `span_name` | | **Start Time Column** | Default value: `timestamp` | | **Duration Time Column** | Default value: `duration_nano` | | **Duration Unit** | Default value: `nano_seconds` | | **Tags Column** | Multiple selections allowed. Corresponds to columns starting with `span_attributes` (e.g., `span_attributes.http.method`). | | **Service Tags Column** | Multiple selections allowed. Corresponds to columns starting with `resource_attributes` (e.g., `resource_attributes.host.name`). | ![Traces](/grafana/traceconfig.png) ## Prometheus data source Click the "Add data source" button and select Prometheus as the type. Fill in Prometheus server URL in HTTP: ```txt http://:4000/v1/prometheus ``` Click basic auth in the Auth section and fill in your GreptimeDB username and password in Basic Auth Details: - User: `` - Password: `` Click Custom HTTP Headers and add one header: - Header: `x-greptime-db-name` - Value: `` Then click "Save & Test" button to test the connection. For how to query data with PromQL, please refer to the [Prometheus Query Language](/user-guide/query-data/promql.md) document. ## MySQL data source Click the "Add data source" button and select MySQL as the type. Fill in the following information in MySQL Connection: - Host: `:4002` - Database: `` - User: `` - Password: `` - Session timezone: `UTC` Then click "Save & Test" button to test the connection. Note that you need to use raw SQL editor for panel creation. SQL Builder is not supported due to timestamp data type difference between GreptimeDB and vanilla MySQL. For how to query data with SQL, please refer to the [Query Data with SQL](/user-guide/query-data/sql.md) document.
