Screenshot Microservice Prerequisites

This applies to: Visual Data Discovery

Before you can install and use the Screenshot microservice, consider the following browser, memory, thread count, and software prerequisites.

Browser Requirements

The Screenshot microservice uses headless Google Chrome. Chrome-based screenshots include the entire dashboard and can be exported in PNG or PDF formats.

Memory Configuration Considerations

If your use of Symphony includes scheduling dashboard reports, you may need to update this memory setting. The default memory configuration is suitable for handling up to 10 concurrent dashboard reports (different dashboard reports scheduled for the same time). If you need to schedule more concurrent dashboard reports, increase the memory allocation to about one gigabyte (1GB) more for every 15 concurrent reports. See Configure Memory Settings.

Thread Count Considerations

If your use of Symphony includes scheduling dashboard reports, update the Screenshot microservice pool.thread.size setting so it is greater than the number of concurrent reports (see screenshot-service.properties Properties). This setting controls the thread count for Screenshot microservice requests.

Obtain the Software

Before you can install the Screenshot microservice, contact Symphony Technical Support to obtain a download link for the Screenshot microservice installation software. Be sure you specify the operating system you are using so the appropriate software is provided.
