Datadog Agent is a critical component of the Datadog monitoring platform. It is a lightweight software that collects metrics, logs, and traces from your infrastructure and applications. The Agent runs on your hosts and sends data to Datadog, where you can visualize and analyze it in real-time. For more information, visit the official Datadog Agent documentation.
One common issue users encounter is the Datadog Agent not collecting process metrics. This symptom is observed when expected process data is missing from the Datadog dashboard, leading to incomplete monitoring insights.
In the Datadog dashboard, you may notice that the process metrics section is empty or not updating. This can hinder your ability to monitor application performance effectively.
The root cause of this issue often lies in the configuration settings of the Datadog Agent. Specifically, process metrics collection might not be enabled, or the Agent may lack the necessary permissions to access process data.
By default, the Datadog Agent may not have process collection enabled. This is a common oversight during initial setup or configuration changes.
To resolve the issue of the Datadog Agent not collecting process metrics, follow these steps:
datadog.yaml configuration file located in the Agent's configuration directory. For Linux, this is typically /etc/datadog-agent/.process_config section and ensure it is uncommented and set to enabled: 'true'.sudo systemctl restart datadog-agent.sudo tail -f /var/log/datadog/agent.log.datadog-agent status to verify that the process collection is active and no errors are reported.For more detailed guidance, refer to the Datadog Process Monitoring documentation. Additionally, the Datadog Community Forum is a valuable resource for troubleshooting and advice from other users.
