Screenshot Microservice Upgrade Notes

After upgrading, the screenshots on the Home page may look different. This occurs if there has been a change in the screenshot aspect ratio. To make the screenshots look correct, make sure that the screenshot.daemon.enabled property in the zoomdata.properties file is set to true. Remember to restart the Composer server microservice after the change (see Restart Composer Microservices).

After you have updated the properties file, you can update the screenshots in one of the following ways:

• In the zoomdata.properties file, modify the screenshot.daemon.schedule.rate property and set it to a more frequent refresh rate.

• Execute a cURL call to update a screenshot for a specific dashboard.

• Execute a cURL call to upload a custom image for a specific dashboard. Otherwise, the screenshots will be updated when the refresh screenshot procedure runs according to the configured refresh rate.
