Red Hat SummitChapter 4. Integrated applications
Cryostat integrates with specific applications that can enhance how you analyze data from your JFR recording.
4.1. Viewing a JFR recording on Grafana
Cryostat 4.0 integrates with the Grafana application, so you can plot JFR recording data in Grafana. You can view plot data in time interval sections to precisely analyze the performance of your target JVM application.
Prerequisites
- Entered your authentication details for your Cryostat instance.
- Created a JFR recording. See Creating a JFR recording in the Cryostat web console.
Procedure
- Go to the Recordings menu or the Archives menu on your Cryostat instance.
- Depending on your needs, click either the Active Recordings tab or the Archived Recordings tab.
Locate your JFR recording and then select the overflow menu.
Figure 4.1. Overflow menu items available for an example JFR recording
- From the overflow menu, click the View in Grafana option. The Grafana application opens in a new web browser window.
- Enter your Red Hat OpenShift credentials in the Grafana web console login page, if prompted. A dashboard window opens and shows your JFR recording’s data in various time-series plots.
Optional: Interact with any plot by selecting a time-series segment on the plot. Grafana expands the on-screen data to show only the data for that time interval.
