New Relic has introduced two new features to improve its NRQL query language: a regular expression filter and the ability to create smooth, accurate charts with sliding time windows. The new features aim to provide users with more flexibility in creating custom charts and data visualizations, allowing them to easily visualize their data and gain high-level insights. Additionally, New Relic has introduced nested queries, which enable users to simplify their data further by reducing cardinality by multiple degrees. These updates are designed to enhance the overall user experience of using NRQL, making it easier for users to get started with writing custom charts and visualizations. With these new features, users can now create more complex and customized dashboards, including multiple charts, and filter their queries with regular expressions. The introduction of sliding time windows also allows users to smooth out data points, resulting in clearer signaling and better visualization of trends.
