How to configure DD_DOGSTATSD_MAPPER_PROFILES in datadog airflow integration? - airflow

Question

I installed datadog-agent using helm upgrade/install and provided the -f datadog.yaml parameter. The datadog.yaml contains this entry:
...
agents:
enabled: true
useConfigMap: true
customAgentConfig:
# Autodiscovery for Kubernetes
listeners:
- name: kubelet
config_providers:
- name: kubelet
polling: true
- name: docker
polling: true
apm_config:
enabled: false
apm_non_local_traffic: true
dogstatsd_mapper_profiles:
- name: airflow
prefix: "airflow."
mappings:
- match: "airflow.*_start"
name: "airflow.job.start"
tags:
job_name: "$1"
- match: "airflow.*_end"
name: "airflow.job.end"
tags:
job_name: "$1"
- match: "airflow.operator_failures_*"
...
But I don't see DD_DOGSTATSD_MAPPER_PROFILES env variable in the datadog-agent pod.
How can I inject this env variable to the datadog-agents?
Update 2/24/2022: I do see it's been added as a ConfigMap but it does not look like it is being mounted to the datadog-agent pod.
Update 3/4/2022: This yaml is working and I see the metrics in datadog dashboard. I do see it got mounted on the datadog-agent pod as config-map.

Use this in your datadog's helm chart:
datadog.env:
- name: DD_DOGSTATSD_MAPPER_PROFILES
value: >
