Hi @Soma

The node_timeline system table in Databricks is designed to provide historical observability across your account. However, if you’re not seeing any data in the node_timeline table, there are a few considerations to keep in mind:

  1. Unity Catalog-Enabled Workspace:

  2. System Table Availability:

  3. Audit Logs and Table Access Control (TAC):

  4. Known Issues and Workarounds:

 

Hi, your response is not helpful. Explaining the reasons why it's a silly response.

1. Someone can't access system tables without enabled Unity Catalog.
2. node_timeline table is not yet covered in the documentation but it's showing up in the system tables.
3. Without access control, someone wouldn't see the table but the query is about null values (not seeing any data).
4. The columns in node_timeline table are not available in any other system table, and so no workaround is possible.

I have seen many Databricks customers facing this issue. I think, Databricks hasn't filled the system tables data. The query is to get an understanding of timelines by when can we start to see the data in node_timeline table. Also, we are wondering if it is still in private preview.
