Hi,

Your question is a bit vague—could you clarify what specifically is not being calculated in Phoenix with your PostgreSQL backend? Are you referring to metrics, evaluations, latency, or something else? Please provide more details or error messages.If you are experiencing missing or incorrect calculations (such as metrics not updating), known issues include frontend UI not reflecting filtered metrics even though the backend returns correct data, or backend errors due to malformed data or large datasets. For example, header metrics like Total Cost may not update with filters in the UI, but the backend GraphQL query works as expected. Also, performance bottlenecks or malformed data in PostgreSQL can cause calculation failures or missing results in the UI. Please specify the calculation or metric you are referring to for more targeted help. According to this issue and this issue, these are common causes.Would you like more detail or troubleshooting steps for a specific calculation or metric?Sources: - https://github.com/Arize-ai/phoenix/issues/10494 - https://github.com/Arize-ai/phoenix/issues/11243
