Before enabling System Activity on a customer-hosted Looker deployment with MySQL backend, verify that you have properly set up the user for the backend database. Specifically, you must perform the step to
grant all on looker_tmp.* to '<DB_username>'@'%';before you enable the System Activity feature. See the procedure on this documentation page.
If you have enabled the System Activity Model feature in Looker Labs, then Looker admins and users who have been granted the see_system_activity permission have access to Looker’s System Activity Explores:
The System Activity Explores connect to Looker’s underlying application database. They show information about your Looker instance, including Looks and dashboards saved on your instance, user information, 90 days of historical queries, and instance performance statistics. This data can be useful for monitoring and auditing purposes. The System Activity data is backed up daily, as discussed on the Backup documentation page.
Chat Team Tip: Time-based data in System Activity is stored in the Looker System time zone. See the Using Time Zone Settings documentation page for more information.
