Hello everyone,
We are pleased to announce the release of Cryostat 2.3!
What’s New in 2.3?
- Cryostat Agent: an agent can be included in your deployment, which facilitates application discovery and JFR operations over HTTP API
- Cross-namespace target discovery: a
ClusterCryostatcustom resource can be configured to communicate with applications deployed across multiple namespaces - Web interface enhancements:
- Quick starts and Guided Tour: short tutorials on how to navigate and perform basic functions in Cryostat
- Topology view with bulk actions: view your deployed applications in a topology view and create JFR recordings in bulk
- Customizable dashboards: view and configure cards displaying your JVM metrics on a dashboard
- Podman API: Discover target applications using Podman HTTP API. This requires the Podman service to be running.
You might try
systemctl --user enable --now podman.socket. The next time you run Cryostat under your user, it will be able to talk to Podman and query for running containers with the labelio.cryostat.connectUrl. The value of this label is expected to be a JMX service URL for the JVM within the container.
What’s Next?
- Additional types of analyses and visualizations
- Smart triggering of JFR start/stop based on JVM conditions
Where can I get the latest version of Cryostat?
You can install Cryostat using our Kubernetes operator on OperatorHub.io or via a Helm Chart . As always, you can also run Cryostat in other environments with a little more manual setup.
If this is your first time installing Cryostat on Kubernetes, you can Get Started right here on this website.
If you had previously installed Cryostat Operator 2.2.0 with OLM, then you may have already been upgraded to 2.3.0, or else you should be able to approve and install the upgrade.
