This page provides you with instructions on how to extract data from Amazon RDS and analyze it in Grafana. (If the mechanics of extracting data from Amazon RDS seem too complex or difficult to maintain, check out Stitch, which can do all the heavy lifting for you in just a few clicks.)
What is Amazon RDS?
Amazon RDS (relational database service) lets users spin up cloud-based database instances without worrying about infrastructure provisioning or software maintenance or many of the administrative tasks involved in running a database on premises.
Cloud platforms can scale up or down quickly to meet changing demands. RDS takes advantage of that capability to let users add database instances to as needed. It offers automatic backup and recovery for database instances, and can replicate data across multiple zones for high availability.
RDS supports six different database engines: Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle Database, and Microsoft SQL Server.
What is Grafana?
Grafana is an open source platform for time series analytics. It can run on-premises on all major operating systems or be hosted by Grafana Labs via GrafanaCloud. Grafana allows users to create, explore, and share dashboards to query, visualize, and alert on data.
Getting data out of Amazon RDS
The most common way to get data out of any database is to write SQL SELECT queries. As part of any query you can join tables, specify filters, and sort and limit results.
Loading data into Grafana
Analyzing data in Grafana requires putting it into a format that Grafana can read. Grafana natively supports nine data sources, and offers plugins that provide access to more than 50 more. Generally, it's a good idea to move all your data into a data warehouse for analysis. MySQL, Microsoft SQL Server, and PostgreSQL are among the supported data sources, and because Amazon Redshift is built on PostgreSQL and Panoply is built on Redshift, those popular data warehouses are also supported. However, Snowflake and Google BigQuery are not currently supported.
Analyzing data in Grafana
Grafana provides a getting started guide that walks new users through the process of creating panels and dashboards. Panel data is powered by queries you build in Grafana's Query Editor. You can create graphs with as many metrics and series as you want. You can use variable strings within panel configuration to create template dashboards. Time ranges generally apply to an entire dashboard, but you can override them for individual panels.
Keeping Amazon RDS data up to date
At this point you've coded up a script or written a program to get the data you want and successfully moved it into your data warehouse. But how will you load new or updated data? It's not a good idea to replicate all of your data each time you have updated records. That process would be painfully slow and resource-intensive.
The key is to build your script in such a way that it can identify incremental updates to your data. You can identify key fields that your script can use to bookmark its progression through the data, and pick up where it left off as it looks for updated data. Auto-incrementing fields such as updated_at or created_at work best for this. When you've built in this functionality, you can set up your script as a cron job or continuous loop to get new data as it appears in your database.
From Amazon RDS to your data warehouse: An easier solution
As mentioned earlier, the best practice for analyzing Amazon RDS data in Grafana is to store that data inside a data warehousing platform alongside data from your other databases and third-party sources. You can find instructions for doing these extractions for leading warehouses on our sister sites Amazon RDS to Redshift, Amazon RDS to BigQuery, Amazon RDS to Azure SQL Data Warehouse, Amazon RDS to PostgreSQL, Amazon RDS to Panoply, and Amazon RDS to Snowflake.
Easier yet, however, is using a solution that does all that work for you. Products like Stitch were built to move data automatically, making it easy to integrate Amazon RDS with Grafana. With just a few clicks, Stitch starts extracting your Amazon RDS data, structuring it in a way that's optimized for analysis, and inserting that data into a data warehouse that can be easily accessed and analyzed by Grafana.
