Grafana Cloud uses three query languages for telemetry data. Each query language is optimized for its signal type: PromQL for metrics, LogQL for logs, and TraceQL for traces.

You can also run queries against Loki using LogCLI, the command-line interface to Grafana Loki. LogQL is the query language for Grafana Loki.

Grafana supports many types of data sources. Data source queries return data that Grafana can transform and visualize. Each data source uses its own query language, and data source plugins each implement a query-building user interface called a query editor.

In Grafana, queries fetch and transform data from data sources, which include databases like MySQL or PostgreSQL, time series databases like Prometheus or InfluxDB, and services like Amazon CloudWatch or Azure Monitor.

Grafana supports the SQL query language for InfluxDB 3.x and newer cloud products (Cloud Serverless, Cloud Dedicated, Clustered).

# Example: Using the query editor in Grafana SELECT cpu_usage, memory_usage FROM system_metrics WHERE host = 'server01'; PromQL (Prometheus Query Language) is used for querying time series data in Prometheus.

Builder mode: Visual interface for constructing queries without writing PromQL directly. Code mode: Text editor with autocomplete for writing PromQL directly. Grafana synchronizes both modes, allowing you to switch between them.

The ES|QL query editor lets you query Elasticsearch using ES|QL (Elasticsearch Query Language), a pipe-based query language. Unlike Lucene queries that rely on aggregation configuration in the builder UI, ES|QL lets you express filtering, ...

Expressions are meant to augment data sources by enabling queries from different data sources to be combined or by providing operations unavailable in a data source. ... When possible, you should do data processing inside the data source. Copying data from storage to the Grafana server for processing is inefficient, so expressions are targeted at lightweight data processing.

Grafana supports many types of data sources. Data source queries return data that Grafana can transform and visualize. Each data source uses its own query language, and data source plugins each implement a query-building user interface called a query editor.

Grafana workspace panels use Queries to communicate with data sources to get data for the visualization. A query is a question written in the query language that is used by the data source. If the query is properly formed, the data source responds.

They allow you to easily query and transform your data after the data source returns it, using SQL, which provides a familiar and powerful syntax that can handle everything from simple filters to highly complex, multi-step transformations. In Grafana, a server-side expression is a way to transform or calculate data after Grafana retrieves it from the data source, but before Grafana sends it to the frontend for visualization.

December 30, 2023 - Before getting started with InfluxDB and Grafana — a powerful duo for data management and visualization — you need to choose between three query languages: InfluxQL, SQL, or Flux.

Grafana supports many types of data sources . Data source queries return data that Grafana can transform and visualize. Each data source uses its own query language, and data source plugins each implement a query-building user interface called a query editor.

October 2, 2020 - There are two line filters: |= "metrics.go" and !="out of order". Of the log lines identified with the stream selector, the query results include only those log lines that contain the string “metrics.go” and do not contain the string “out of order”.

Grafana includes a Graphite-specific query editor to help you build queries. The query editor helps you quickly navigate the metric space, add functions, and change function parameters.
