What databases work with Grafana?
Grafana supports a variety of databases that can be used as data sources for visualization and monitoring. Some of the popular databases that work with Grafana include Prometheus, InfluxDB, Graphite, Elasticsearch, MySQL and PostgreSQL, Microsoft SQL Server, Cloud Provider Databases like Amazon Web Services (AWS) RDS, Google Cloud SQL, and Azure Database. It also works with other databases that include TimescaleDB, OpenTSDB, SQLite.
What are metrics and visualizations in Grafana?
Metrics tell you how much of something exists, such as how much memory a computer system has available or how many centimeters long a desktop is. In the case of Grafana, metrics are most useful when they are recorded repeatedly over time. This permits us to compare things like how running a program affects the availability of system resources.
Metrics like these are stored in a time series database (TSDB), like Prometheus, by recording a metric and pairing that entry with a time stamp. Each TSDB uses a slightly different data model, but all combine these two aspects and Grafana Cloud can accept their different metrics formats for visualization.
Visualize existing observability data:
Visualizations are the graphical representations of these metrics, such as graphs, tables, and gauges.
Grafana Cloud runs the same open source Grafana platform deployed by thousands of DevOps and SREs, but is managed and optimized by Grafana maintainers and contributors, so you don’t have to worry about downtime, upgrades, and high-availability for your metrics visualization platform.
You can visualize observability metrics from existing data sources running in your environment and managed data endpoints built-in to Grafana Cloud.
Start visualizing
Plug in your data sources: Grafana natively supports many popular data sources like Prometheus, Elasticsearch, and Amazon CloudWatch, and offers plugins for many more. The Grafana plugin library contains over 40 data source plugins for many popular data stores, cloud services, and applications, all with one-click installation into Grafana Cloud. Integration with Grafana Cloud metrics and logs endpoints comes built-in and pre-configured. See the Grafana data sources documentation for details.
Import a Grafana dashboard: There are hundreds of official and community-built Grafana dashboards that you can import to get visibility into your apps and infrastructure. To learn how to import a dashboard into Grafana Cloud, please see Importing a Dashboard from the Grafana docs.
Explore your metrics data: Using PromQL, you can select and aggregate time series data in real time and visualize it in a graph or table. Grafana’s Explore view allows you to optimize and debug queries, as well as view metrics, logging, and tracing data side by side to dig into incidents and events. To learn more about using Grafana’s Explore view, please see Explore from the official Grafana docs.
Explore tracing data: Using TraceQL, a query language modeled on PromQL and LogQL, you can interactively extract insights from your trace data. You can use the Tempo data source Search and query editor to create TraceQL queries.
What is the difference between Grafana vs Prometheus?
Grafana or Prometheus: Which One is Better?
Breaking down complex data in an understandable manner will be the first choice for any organization.
Grafana, unlike Prometheus, provides maximum options of breaking down data into an understandable form.
With its feature of supporting multiple databases, it helps in creating a much better understanding of data.
Prometheus specializes in event monitoring and has very little to do with the visualization part. Even it has to be dependent on Grafana for better optimization of data.
With the above discussion, it becomes quite evident that Grafana would be a better option to opt for when it comes to doing complete justice with data.
