This is KubeCon Europe week, and at Timescale, they're releasing new features and content every day focused on Promscale and observability. Prometheus Recording Rules allow creating new metrics from existing ones using PromQL, which can be useful for downsampling data. Promscale supports both Prometheus' Recording Rules and TimescaleDB's continuous aggregates, giving users flexibility to choose the method that better adapts to their metric needs. Configuring Recording Rules in Promscale involves creating a YAML file with a list of PromQL rules, similar to Prometheus, and can be used to pre-calculate metrics like CPU usage rates. Users can try out Promscale for free by installing it from the GitHub repository and executing a Docker Compose command. With this new functionality, users can save machine resources while maintaining access to alerting and recording rules.
