Question

Does Prefect discard the data for old flow runs maybe ones older than 14 days In particular I had a failed run from Aug 31 <https cloud prefect io zesty ai flow run 385b3c9b 8828 4b46 bda7 5ea32642b266> and today I was going to get around to poking at the bug causing it to fail but instead I see a mostly blank page with lots of Uncaught TypeError Cannot read properties of null reading state in the JS console see attached screenshot In case it matters this is for old Prefect not 2 0

Also I ask if 14 days is significant because when I look at either the dashboard or a specific flow I can only seem to see a run history for 14 days ago See attached screenshot

Hi Ben that s correct flow logs are retained only for 14 days by default Additional length of time for log retention is possible with enterprise features

Ah I see Thanks

Christopher Boyd · Answer

One possibility we have seen is to capture and log to your own location storage

Christopher Boyd · Answer

If you need longer than 14 days retention but not enterprise features

Is there a good official ish way to capture the `prefect context logger` Like to just wrap it so that you can do what you want with each log first before letting the logger then do whatever it usually does i e store logs in Prefect Cloud

Ben Ayers-Glassey · Answer

We have many Prefect flows but using a common library with helpers for setting up Prefect stuff so maybe we can just update the library to wrap the logger or something

Christopher Boyd · Answer

Generally yea it would just be logging your output and capturing it where ever you want you have the option with the loggers to specify the i O stream like a file or location or datadog or an s3 bucket

Christopher Boyd · Answer

We d still capture in prefect for the fourteen days

Christopher Boyd · Answer

But then you d have your own elsewhere
