Disable all Custom CloudWatch Metrics for MWAA

Question

I want to disable all the custom cloudwatch metrics generate by my airflow environment.

I read about the `metrics.metrics_block_list` config [here](https://docs.aws.amazon.com/mwaa/latest/userguide/access-metrics-cw-202.html#choosing-metrics). So I added

`metrics_block_list = scheduler,executor,dagrun,dag,pool,triggerer,celery,ti,task`

(not sure if those are all relevant prefixes) as a custom config to the environment.  But i still get the metrics.

Then i tried

```
metrics.metrics_use_pattern_match = true
metrics.metrics_block_list = ^.*$
```
But this does not have an effect either.
Also, wenn locking in the config in the UI (by setting `webserver.expose_config` to true) i see that the value are still empty / false.

What am I missing?

Setting `metrics.statsd_on = False` disabled all the custom metrics.

You may try this:

1. Use Environment Variables Instead of airflow.cfg
MWAA prefers environment variables for config overrides. Try setting:

```
AIRFLOW__METRICS__METRICS_BLOCK_LIST=^.*$
AIRFLOW__METRICS__METRICS_USE_PATTERN_MATCH=true
```

Add these as custom environment variables in the MWAA console.
2. Double-Check MWAA Version Compatibility
Some metrics settings are only supported in Airflow 2.3+. Confirm your MWAA environment is running a compatible version.
3. Restart the Environment
After applying config changes, restart the MWAA environment to ensure they take effect.
4. Verify with CloudWatch Logs
Check the MWAA logs in CloudWatch to confirm whether metrics are still being emitted. Sometimes metrics are cached or delayed.

Hi,
thank you for the answer
1) where can i set environment variables explicitly? afaik the environment config (e.g. in the porlta) is converted to environment variables. Thats what i am doing.
2) Version 2.10, so this should be fine
3) Restart was done
4) Metrics are still there

So in general you say the config itself should be fine?
