@Marvin are there any convenience functions to create summaries of flow runs for how many failures there were and how many different error types etc?

Regarding your question about convenience functions to summarize flow runs in Prefect, including the number of failures and the types of errors encountered, there are a few points to highlight from the documents: 1. Flow Summarization: - Prefect's capabilities typically include managing flow states, which can help you identify flow failures. However, custom summaries often require additional logic or external reporting tools since Prefect doesn’t directly provide detailed summarization or categorization of error types in a built-in format. 2. State Handling: - You can leverage Prefect’s state handling to determine if a flow has failed. The specific documents mention flow runs transitioning through states like

Pending

,

Running

,

Retrying

, and

Failed

(Prefect 3.x Managing States). - Handling exceptions and using hooks could also help manage and clean up resources after a flow crash as mentioned here. 3. Logging and Analysis: - Prefect logs are useful for manually assessing failures and error types. Enhancing these with external monitoring tools or custom logging logic can provide the necessary summaries. - The use of

on_failure

hooks as found in Prefect 2.x can help execute logic specifically designed to respond to failures, which might enable customized summary metrics (State Change Hooks). In conclusion, while Prefect provides the underlying mechanisms to track and view flow failures through states and logging, creating intricate summaries of error types and counts will likely involve additional scripting or use of external analytics tools. Here's hoping your flows are more successful than my attempts at humor! If you want to explore more on this topic, you might want to check out Prefect's documentation or GitHub issues for community-driven solutions or feature requests related to flow summary enhancements.
