Question

So I have prefect server running on some dev instances and a uat qa instance and then I have production using prefect cloud I want ALL logging to go to a graylog server via graypy I ve found that when I run the flow via the command line in the docker container it sends all the logging to my graylog server however when I run the flow from the UI server or cloud it doesn t set my handler Where s the appropriate place to put this

``` logger = prefect context get logger logger setLevel logging DEBUG handler = graypy GELFTLSHandler 10 11 12 13 12345 fqdn=False localname=os environ get PREFECT ENV logger addHandler handler ```

Hi < Corris Randall> I think this sounds like the handler is being added in the Flow block The content of the Flow block is not deferred it is executed eagerly and builds the DAG Adding the handler here only attaches it during registration time but not during the Flow run time You can try using `stored as script=True` in the Flow storage that the Flow is not serialized and this will be executed during runtime You can also put this inside a task but you might need to add it in every task if you do it that way This will work because task execution is deferred so attaching the handler will happen during the flow run

Ah ok I ll give that a shot putting it in the task doesn t really work because that just gets the logs from that task I d like the whole execution logs to be sent to graylog

that worked the agent is actually running in the docker container it seems most people are doing it the other way around anyways here s my local flow storage for dev qa

```flow storage = Local add default labels=False stored as script=True path= flows +os path basename inspect stack 1 1 ```

argh slack formatting is wack anyways the stack inspection is because I m using a setup function in a custom module to define consistent flow parameters setup Thanks again
