If you are using Databricks serving endpoint, and you wish to export metrics to Datadog, you can face with some challenges in Datadog documentation. This article will help you to solve them, at least it will help you to make a PoC. Here are list of links which you can use: https://docs.databricks.com/en/machine-learning/model-serving/metrics-export-serving-endpoint.html https://docs.datadoghq.com/agent/basic_agent_usage/ubuntu/?tab=agentv6v7 Databricks serving endpoint is a service which allows you to deploy your model and serve it. It is a part of Databricks MLflow. You can find more information about it here: https://docs.databricks.com/applications/mlflow/model-serving.html Once you created an endpoint, out of the box you can see some metrics in Databricks UI. Also list of metrics can be received via REST API: curl --request GET "https://${DATABRICKS_HOST}/api/2.0/serving-endpoints/{endpoint_name}/metrics" --header "Authorization: Bearer ${DATABRICKS_TOKEN}" But if you want to export them to Datadog, you need to install and configure Datadog agent. Pre-requisites Created Databricks serving endpoint Bearer PAT token behalf of Databricks user/service principal, which has `CAN_QUERY` permission on the endpoint Datadog API key Enabled OpenMetrics integration in your Datadog account, link: https://app.datadoghq.com/integrations Install Datadog agent Datadog offers several ways to install agent, they are listed here: , however looks like some of them are not working, or at least I was not able to make them work. That is why I decided to use the most simple way — install agent on Docker. https://app.datadoghq.com/account/settings/agent/latest?platform=overview Before agent installation, you need to create a file `datadog.yaml`, which should be located ` `, with the following content: /etc/datadog-agent/datadog.yaml api_key: "__DD_API_KEY__"
site: "datadoghq.com"
hostname: "__YOUR_HOST_NAME__" Then you need to create `metric-config.yaml` file, which should be located ` `, with the following content: /etc/datadog-agent/conf.d/openmetrics.d/conf.yaml.default instances:
 - openmetrics_endpoint: https://__DATABRICKS_HOST__/api/2.0/serving-endpoints/__ENDPOINT_NAME__/metrics

   metrics:
     - cpu_usage_percentage:
         name: cpu_usage_percentage
         type: gauge
     - mem_usage_percentage:
        name: mem_usage_percentage
        type: gauge
     - provisioned_concurrent_requests_total:
        name: provisioned_concurrent_requests_total
        type: gauge
     - request_4xx_count_total:
        name: request_4xx_count_total
        type: gauge
     - request_5xx_count_total:
        name: request_5xx_count_total
        type: gauge
     - request_count_total:
        name: request_count_total
        type: gauge
     - request_latency_ms:
        name: request_latency_ms
        type: histogram

   tag_by_endpoint: false

   send_distribution_buckets: true

   headers:
     Authorization: Bearer __DATABRICKS_TOKEN__
     Content-Type: application/openmetrics-text The full possible options for ` ` can be found in template file which is located in a container under ` ` conf.yaml.default /opt/datadog-agent/agent/conf.d/openmetrics.d/ I’ve created the next , because I have some difficulties with that one which is provided in Datadog documentation: Dockerfile FROM ubuntu:20.04
