• Eat up fewer resources in Cryostat 2.1 with sidecar reports

  Cryostat is a tool for managing JDK Flight Recorder data on Kubernetes. Version 2.1 of Cryostat introduces the option of using a sidecar reports container to generate automated analysis reports for JDK flight recordings. Previously, the main Cryostat container handled the report generation. Report generation is a resource-intensive operation, and as a result, users may find themselves overprovisioning the Cryostat container to meet peak resource demands. Those resources may in turn end up unused if you're not generating reports. With this new option to delegate report generation to a sidecar container, users will find it easier to provision resources more efficiently. When report generation is not a concern, the main Cryostat container, including its web server and various lightweight operations over HTTP and JMX, has only a small resource footprint. Based on their report generation workflow, users can provision resources to the sidecar reports container accordingly and spin up any number of replicas of that container.
