What is last_accessed_at and last_viewed_at?

[ginandtobby]

Hi Community!

I'm referring to this endpoint: GET /dashboards/{dashboard_id}. Link: Get Dashboard  |  Looker  |  Google Cloud

There is a last_accessed_at and a last_viewed_at field. Official definition of them are as below:

last_accessed_at: Time the dashboard was last accessed

last_viewed_at: Time last viewed in the Looker web UI

For last_accessed_at, the definition is not helping - what does it mean by `access`? Is it referring to a query run, or someone clicking on the link? While for last_viewed_at, the definition is clear, but it is not real for some dashboards, and there are a lot of null values despite there are actually views for these dashboards.

Please help. Thanks!

'Last accessed' I believe would refer to someone opening the dashboard. A query may not hit the database when someone accesses a dashboard as Looker may pull the data from cache.

On the 'last_accessed_at', I am curious if you know when the dashboards were viewed - the data is coming from the internal database which typically only retains 90 days of data.
