Jeoffreybauvin opened a new issue, #69172:
URL: https://github.com/apache/airflow/issues/69172
### Under which category would you file this issue?
Airflow Core
### Apache Airflow version
3.2.1
### What happened and how to reproduce it?
A while back, I was using a plugin to send custom statsd metrics after a
fail or success dag run :
```
from airflow.stats import Stats
metric_success = f"brs_dag_last_5_runs_states.success.{dag_id}"
metric_failed = f"brs_dag_last_5_runs_states.failed.{dag_id}"
Stats.gauge(metric_success, success_count)
Stats.gauge(metric_failed, failed_count)
```
And it was working fine. But, it's not working anymore : no metric is sent
to my statsd_exporter.
Here is my configuration :
```
AIRFLOW__METRICS__STATSD_HOST: 10.2.218.29
AIRFLOW__METRICS__STATSD_INFLUXDB_ENABLED: 'True'
AIRFLOW__METRICS__STATSD_ON: 'True'
AIRFLOW__METRICS__STATSD_PORT: '9125'
AIRFLOW__METRICS__STATSD_PREFIX: prod
```
Please note : I don't have any issue with the "native" statsd metrics from
Airflow : my stats_exporter is collecting them.
After some debug of the statsd object inside my plugin file :
```
log.info("Stats object: %r", Stats)
for attr in ("_instance", "_logger", "factory"):
log.info("Stats.%s = %r", attr, getattr(Stats, attr, None))
```
```

'airflow.sdk._shared.observability.metrics.stats.Stats'>

```
### What you think should happen instead?
The metrics inside my plugin should be sent to statsd.

### Anything else?
For the time being, I'm sending "manually" the metrics :
```
from functools import lru_cache
from airflow.configuration import conf
from statsd import StatsClient
@lru_cache
def get_statsd_client() -> StatsClient:
return StatsClient(
host=conf.get("metrics", "statsd_host"),
port=conf.getint("metrics", "statsd_port"),
prefix=conf.get("metrics", "statsd_prefix", fallback=None),
)
def statsd_gauge(metric_name: str, value: int) -> None:
get_statsd_client().gauge(metric_name, value)
statsd_gauge(metric_success, success_count)
statsd_gauge(metric_failed, failed_count)
```
