Quick Guide for Datadog Agent on Kubernetes for Logs

1. Add the Datadog Helm repository.

helm repo add datadog https://helm.datadoghq.com
helm repo update

2. Configure datadog-values.yaml.

For pod-level metrics, add Datadog annotations to enable scraping.

3. Base configuration

fullnameOverride: "kfuse-agent"
nameOverride: "kfuse-agent"
datadog:
     apiKey: " "
     #
     # Scenario default: Assumes that Kloudfuse stack & agent both in same VPC and in same K8S cluster
     #
     dd_url: "http://kfuse-ingress-nginx-controller-internal.kfuse/ingester"
     #
     # Scenario 1: Kloudfuse stack & agent both in same VPC, but in different K8S cluster
     #
     # dd_url: "http://<ingress-ip>/ingester"
     #
     # Scenario 2: Kloudfuse stack hosted in a different VPC (hosted at “customer.kloudfuse.io”)
     #
     # dd_url: "https://customer.kloudfuse.io/ingester"
     #

4. Enable logs ingestion.

...
           datadog:
             ...
             logsEnabled: true
             logs:
               enabled: true
               containerCollectAll: true

agents:
             customAgentConfig:
               ...
               logs_config:
                 #
                 # Scenario default: Assumes that Kloudfuse stack & agent both in same VPC and in same K8S cluster
                 #
                 logs_dd_url: "kfuse-ingress-nginx-controller-internal.kfuse:80"
                 logs_no_ssl: true
                 #
                 # Scenario 1: Kloudfuse stack & agent both in same VPC, but in different K8S cluster
                 #
                 # logs_dd_url: "<ingress-ip>:80"
                 #
                 # Scenario 2: Kloudfuse stack hosted in a different VPC (hosted at “customer.kloudfuse.io”). Make sure
                 # to comment out the logs_no_ssl: true default above.
                 #
                 # logs_dd_url: "customer.kloudfuse.io:443"
                 # logs_no_ssl: false
                 #
                 use_http: true
                 auto_multi_line_detection: true
                 use_v2_api: false

5. Verify that the agent runs in the cluster, and that data flows into Kloudfuse.
