# Description This PR attaches the logGroomer sidecar pod when using a standalone `dag processor`. This is to prevent scheduler logs from growing infinitely in the `logs` directory of that `dag processor` pod. In fact, one of the Airflow clusters my team uses had about `3.5 TiB` of scheduler logs accumulated in the emptyDir of a `dag processor` pod, which reduced the ephemeral-storage availability on that node to the point of pod eviction, resulting in a pod eviction. ``` airflow@airflow-test-dag-processor-78f9bfdb88-hmckb:/opt/airflow/logs$ ls scheduler airflow@airflow-test-dag-processor-78f9bfdb88-hmckb:/opt/airflow/logs$ du -sh 3.5T . ``` We haven't figured out why the standalone `dag processor` was accumulating scheduler logs, but we think it's a good idea to attach a logGroomer sidecar like any other scheduler pod or worker pod to prevent this from happening in the first place. In this PR, we've modified the helm chart to attach a logGroomer to the standalone `dag processor`.
