Why each option
When a dashboard's information fails to load properly, the most effective troubleshooting step is to examine the underlying data layer and data source. This involves verifying connectivity, data availability, and the correctness of queries or data transformations that feed the dashboard.
When a dashboard's information isn't loading, the most fundamental step is to review the data layer and data source. This involves checking the connection to the data source, ensuring the data source itself is available and returning expected data, and verifying the queries, connections, or data transformations that feed the dashboard. This addresses the potential root cause of data not being retrieved.
While an outdated database could potentially cause issues, verifying that the database is 'up-to-date' is a more general step. The immediate problem is typically with the data source connectivity or content that the dashboard relies on, which is part of the data layer.
Checking if the dashboard program is updated is a general maintenance step. While a bug in an old version could cause problems, it's less likely to be the direct cause of "information not loading properly" than an issue with the data source itself.
Filters control which data is displayed, but if the information isn't loading properly at all (e.g., blank visuals, error messages), it suggests a problem with data retrieval before filtering can even take effect.
