Asset health status

Asset health status

Gain a deeper understanding of your assets with the health status indicator.

When evaluating the health status of an asset, it's essential to consider various indicators. These indicators give you a well-rounded view of the current state of your asset. They include:

  • Last build status: This reflects the outcome of the most recent build attempt. It could indicate an error state with statuses like Cancelled, Test Failed, or Materialization Failed.
  • Last successful build status: : This tells you about the state of the last successful build. It can be labeled as Stale or Never Materialized in case warnings are to be noted.
  • Asset's label: It notes the current status of the asset, pointing out if there are issues or if it has been Deprecated.
  • Code integrity status: It indicates the condition of the asset within the code editor, flagging errors like Syntax Error or Invalid reference (in the model definition), or warnings such as Uncommitted Changes or SQLFluff Formatting Warning.

Understanding the health status indicator

To effectively interpret the asset's health status, it's critical to navigate through the conditions from right to left and from bottom to top, in terms of severity. Let's look at some examples:

Right to left:

  • If the "Last Successful Build Status" indicates Stale, but the "Last Build Status" shows Materialized Failed, the latter takes precedence due to its higher priority, thus flagging the asset as being in Error ❌ health status.

Bottom to top severity:

  • If a Stale status coincides with Uncommitted Changes, it translates to a Warning ⚠️ health status, with the alert message pointing to the Stale condition (the error message is deduced based on the right-to-left rule as the two conditions are on the same severity).
  • However, if the Stale status is accompanied by an Invalid Reference issue, this will supersede the stale warning, prompting a more severe health status ❌.

Thus, this evaluation process, moving from right to left and ascending in severity from bottom to top, helps in accurately pinpointing the critical issues that need urgent attention.

Asset stale status

The Stale status is triggered when the asset configurations are changed, impacting downstream assets linked to it. The stale status serves as a notification that these linked models may now contain outdated information due to recent changes.

In this example, changes to the logic of the stg_products asset mark it as stale. This occurs because the code is no longer in sync with the data warehouse materialization, affecting not only the asset itself but also the downstream mrt_purchases asset.

You can use the following command to build all stale assets in a space:


y42 build --stale

Asset Label

In the platform, users have the flexibility to categorize their assets using specific labels to streamline management and monitoring. These labels help in quickly identifying the current state of an asset. The available labels to classify an asset are:

  • No Status: The asset is newly created or its status has not been determined yet.
  • Issue: This label indicates that the asset is currently facing problems or irregularities that need attention.
  • Draft: The asset is in a preliminary stage and may be subject to further modifications.
  • Deprecated : This label is applied to an asset that is no longer recommended for use, generally because it has been replaced by a newer version or functionality.
  • Verified : This signifies that the asset has been reviewed and confirmed to be functioning as expected.

You can easily apply these labels to keep track of asset statuses and facilitate smoother workflow processes.

Asset Tiers

In order to prioritize and manage your assets more effectively, you can designate different Tier levels to them. These tiers help in distinguishing the criticality and importance of each asset, aiding in efficient resource allocation and focus. The tier levels are as follows:

  • Tier 1 - Critical: Assets that are vital and form the backbone of the operation. Any disruption to these assets can have significant repercussions.
  • Tier 2 - Important: Assets that have a high value and contribute considerably to the overall function, but are not as critical as Tier 1 assets.
  • Tier 3 - Regular: These are the assets that perform standard functions and are necessary for routine operations but are not in the high priority bracket.
  • Tier 4 - No Tier: Assets that are currently not categorized or do not fall under any critical functionality or importance bracket.
