Hi, I'm new to prefect and I'm trying to use it to evaluate the performance of code / parameter changes. I've created a basic flow but cannot figure out how to get historical metrics on each of the tasks. Is there something that I'm missing? My hope would be to get a table that looks like: | Flow Name | Parameters | Task Name | Start Time | End Time | Duration | I've tried going through the graphQL api and I've looked through the UI. Any direction would be appreciated.

Hi @Dan Corbiani - you should be able to query for these using the GraphQL API, or see them in a UI (but in a non-aggregate way at the moment). Try a query like this:

query {
  flow_run(where: {name: {_eq: ""}}) {
    id
    name
    parameters
    start_time
    end_time
    task_runs {
      start_time
      end_time
    }
  }
}

thanks @nicholas. I was so close. Is there also a way to get something like this when running the workflow through flow.run() in python?

Sure, you can use the graphql client from core to query for that!
