Absolutely simple metrics with Flex

The article delves into the use of New Relic Flex for integrating custom data metrics, particularly focusing on scenarios where pre-made New Relic agents and quickstarts fall short. It provides a detailed tutorial on using scripting to reformat and combine data outputs from multiple commands, with a specific example involving internet speed testing using Ookla's Speedtest.net utility. The tutorial includes steps on installing the utility, processing its output to display download and upload speeds in Mbps using a Python script, and configuring New Relic Flex to visualize these metrics on a dashboard. The article also discusses troubleshooting techniques, such as running Flex manually and setting up logging to ensure the integration functions correctly, and provides NRQL queries for displaying data in New Relic. The content is authored by Leon Adato, a Developer Relations Engineer at New Relic, and emphasizes the importance of adapting solutions to specific environments while encouraging engagement in the Explorers Hub for further discussion and support.
